本文档包括改专题的：外文文献、文献综述一、外文文献Financial synergy in mergers and acquisitions. Evidence from Saudi ArabiaAbstractBusinesses today consider mergers and acquisitions to be a new strategy for their company's growth. Companies aim to grow through increasing sales, purchasing assets, accumulating profits and gaining market share. Thus; the best way to achieve any of the above-mentioned targets is by getting into either a merger or an acquisition. As a matter of fact, growth through mergers and acquisitions has been a critical part of the success of many companies operating in the new economy. Mergers and acquisitions are an important factor in building up market capitalization. Based on three structured interviews with major Saudi Arabian banks it has been found that mergers motivated by economies of scale should be approached cautiously. Similarly, companies should also approach vertical mergers cautiously as it is often difficult to gain synergy through a vertical merger. Firms should seek out mergers that allow them to acquire specialized knowledge. It has also been found that firms should look for mergers that increase market power whilst avoiding unrelated mergers or conglomerate mergers.Keywords: Synergy, Mergers and Acquisitions, Saudi Arabia 1. IntroductionThere is a major difference between mergers and acquisitions. Mergers occur between similarly sized companies and the collaboration is "friendly" between both companies. However, Acquisitions often occur between differently sized companies and the partnership is usually forced and hostile.Wheelen and Hunger (2009) define a merger as a transaction involving two or more corporations in which stock is exchanged but in which only one corporation survives. In other words, the two companies become one and the name for the corporation becomes composite and is derived from the two original names. Furthermore, an acquisition is the purchase of a company that is completely absorbed as an operating subsidiary or divisionof the acquiring corporation (Wheelen and Hunger, 2009). The authors also state thathostile acquisitions are called takeovers.The main reason for firms entering into mergers and acquisitions (M&A) is to grow, andcompanies grow to survive (Akinbuli, 201 2). Growth strategies expand the company's activities and add to its value since larger firm have more bargaining power than smaller ones. A firm sustaining growth will always have more opportunities for advancement, promotions and more jobs to offer people (Wheelen and Hunger, 2009). In general, mergers and different types of acquisitions are performed in the hope of realizing an economic gain. For such a business deal to take place, the two firms involved must be worth more together than each was apart.A few of the prospective advantages of M&A include achieving economies of scale, combining complementary resources, garnering tax advantages, and eliminating inefficiencies. Other reasons for considering growth through acquisitions contain obtaining proprietary rights to products or services, increasing market power by purchasing competitors, shoring up weaknesses in key business areas, penetrating new geographic regions, or providing managers with new opportunities for career growth and advancement (Brown, 2005).Many firms choose M&A as a tool to expand into a new market or new area of expertise since it is quicker and cheaper than taking the risk alone. Furthermore, M&A happen when senior executives feel enthusiastic and excited about a potential deal ; the idea of successfully pursuing and taking over another company before the company s competitors are able to do so. Competition in a growing industry drives firms to acquire others. In fact, a successful merger between companies increases benefits for the entire corporation.However, failures also occur in M&A as indicated by Haberbserg and Rieple (2001) and Akinbuli (2012). They showed that 50% of acquisitions are unsuccessful; they increase market power but do not necessarily increase profits. Brown (2005) explains the reasons for the high failure rate of M&A as follows:(a)Over-optimistic assessment of economies of scale. Economies of scale are usually achieved at certain business size. However, expansion beyond the optimum level results in disproportionate cost disadvantages that lead to various diseconomies of scale.(b)Inadequate preliminary investigation combined with an inability to implement the amalgamation efficiently. Resistance to change and the inability for the acquired company to manage change well is a main reason for failure due to the resistance of the employees and management of both companies involved.(c)Insufficient appreciation of the personnel problems, which will arise, is due mainly to the differing organizational cultures in each company.(d)Dominance of subjective factors such as the status of the respective boards of directors.Therefore, drafting careful plans before and after the merger is a necessity that should not be overlooked. Some companies find the solution in hiring a change manager who will add value and better manage the transition of the "marriage between both companies" (Brown, 2005).2.Synergy in M&A and financial synergyThis section discusses the literature review in order to identify the importance of acquiring financial synergy in the M&A.2.1Synergy in M&ASynergy, as defined in the business dictionary, is the state in which two or more agents, entities, factors, processes, substances, or systems work together in a particularly fruitful way that produces an effect greater than the sum of their individual effects. Synergy is the magic force that allows for enhanced cost efficiencies of the new business. Synergy takes the form of revenue enhancement and cost savings (Mergers and acquisitions: Definition, n.d.).Synergy is also expressed as an increase in the value of assets as a result of their combination. Expected synergy is the justification behind most business mergers. For example, the 2002 combination of Hewlett-Packard and Compaq was designed to reduce expenses and capitalize on combining Hewlett-Packard's reputation for quality with Compaq's impressive distribution system (Synergy Business Definition, n.d.).Through research it has been noted that synergy is the concept that two businesses will generate greater profits together than they could separately (Wheelen and Hunger, 2009). Synergy is said to exist for a divisional corporation if the return on investment of each division is greater than what the return would be if each division were an independent business (Wheelen and Hunger, 2009). In order to succeed cooperation between the partners is the basic ingredient for achieving growth through synergy (Rahatullah, 201 0). This requires partners to build trust, commitment, and secure consensus, to achieve their targets (Gronroos, 1997; Ring and Van-de-Ven, 1994).Synergy can take several forms. According to Goold and Campbell (1 998) synergy is demonstrated in six ways: benefiting from knowledge or skills, coordinated strategies,shared tangible resources, economies of scale, gaining bargaining power over suppliers and creating new products or services.M8<A result in the creation of synergies, the sharing of manufacturing facilities, software systems and distribution processes. This type of synergy is referred to as operational synergy and is seen mostly in manufacturing industries. Another motive for forming an acquisition is gaining greater financial strength by purchasing a competitor, which increases market share. The aim of mergers and acquisitions is to achieve improvement for both companies and produce efficiency in most of the company's operations. (Haberberg and Rieple, 2001).However, Brown (2005) summarizes the sources of synergy that result from M8<A underthe following headlines:1.Operating economies which include:(a)Economies of scale: Horizontal mergers (acquisition of a company in a similarline of business) are often claimed to reduce costs and therefore increase profits due to economies of scale. These can occur in the production, marketing or finance divisions.Note that these gains are not expected automatically and diseconomies of scale may also be experienced. These benefits are sometimes also claimed for conglomerate mergers(acquisition of companies in unrelated areas of business) in financial and marketingcosts.(b)Economies of vertical integration: Some acquisitions involve buying out other companies in the same production chain. For example, a manufacturer buys out a rawmaterial supplier or a retailer. This can increase profits through eliminating the middleman in the supply chain.(c)Complementary resources: It is sometimes argued that by combining the strengths of two companies a synergistic result can be obtained. For example, combining a company specializing in research and development with a company strong in the marketing area could lead to gains. Combining the expertise of both firms would benefit each company through the gained knowledge and skills that individually they lack.(d)Elimination of inefficiency: If either of the two companies had been badly managed; its performance and hence its value can be improved by the elimination of inefficiencies through M&A, Improvements could be obtained in the areas of production, marketing and finance.2.Market power; Horizontal mergers may enable the firm to obtain a degree of monopoly power which could increase its profitability. Coordinated strategies between both companies will lead the entire organization in gaining competitive advantage. Gaining bargaining power over suppliers is realized since the company is larger in size after the merger.3.Financial gains; Companies with large amounts of surplus cash may see the acquisition of other companies as the best application for these funds. Shared tangible resources such as sharing a bigger building, more office supplies, equipment, manufacturing facilities and research and design labs will also lead to a reduction in costs translated into better financial performance. McNeil (2012) identifies that the shareholders of a business under M&A process may benefit from the sale of their stocks, this is especially true if the M&A is with a better, bigger and more reputable prospective partner.4.Others; such as surplus management talent, meaning that companies with highly skilled managers can make use of their qualified personnel only if they have problems to solve. The acquisition of inefficient companies allows for maximum utilization of skilled managers. Incorporating the efforts of both management teams will drive the creation of innovative products or services.The synergy factor prevails in the M&A when the firms produce a greater return than the two individual firms owing to reasons such as improvements in efficiency and an increase in market power for the merged or acquired firms (Berkovitch and Narayana, 1993).2.2Financial synergyAs defined by Knoll (2008), financial synergies are performance advantages gained by controlling financial resources across businesses of firms. There exist four types of financial synergies, which are:1.Reduction of corporate risk: Reduction of corporate risk is increasing the risk capacity of the overall firm, which means the ability of the firm to bear more risk. Meaning that by increasing the risk capacity the shareholders will invest more in the company and the firm will gain benefits such as coinsurance effects.2.Establishment of internal capital market: Establishing internal capital gains means that the firm will decrease its financing costs and will increase financialflexibility which results in the company having higher liquidity and the ability to payits creditors easily.3.Tax advantages: Tax advantages by reducing the tax liabilities of the firm using the losses in one business to offset profits in the other business referred to as "profit accounting".4.Financial economies of scale: Financial economies of scale reducing transaction cost in issuing debt and equity securities (Knoll, 2008).3.Methodology and resultsFor this project, the method of interviews was used due to it being the most appropriate way to gather information about the interpretation of events, as to why some mergers produce synergy while others do not; and to understand the reasons why companies enter into mergers. In Saudi Arabia it is difficult to secure responses from senior executives. Approaching such a person is not only difficult protocol wise but there are bureaucratic hurdles. The quantitative analysis is more suitable for large scale data collection (Denzin and Lincoln, 1997). Whereas, qualitative research provides the researcher with the perspective of target audience members through captivation and direct interaction with the people under study (Glesne and Peshkin, 1992). These methods help to comprehend what others perceive of a certain phenomenon, postulates Creswell (1994).The planned interview method was to use a structured interview. In a structured interview, the researcher knows in advance what information is needed and asks a predetermined set of questions (Sekaran and Bougie, 2009). The same questions are asked of all interviewees, which allows for better comparison of the responses than unstructured interviews, where the interviewees are asked different questions. The structured interview process does allow the researcher to ask different follow up or probing questions based on the interviewee's response. This allows the interviewer to identify new factors and gain a deeper understanding of the topic (Sekaran and Bougie, 2009).Since the interviewees were located in different parts of Saudi Arabia the interviews were scheduled in advance and conducted face to face. The data was gathered by taking notes during the interviews, which were not recorded as that may have seemed too intrusive.When conducting interviews it is important to conduct them in a manner that is free of bias or inaccuracies. According to Sekaran and Bougie (2009), bias can be introduced by theinterviewer, interviewee or the situation. Interviewers can introduce bias by distorting the information that they hear so it aligns with their expected responses to the question or through simple misunderstandings. To prevent this, the respondents' answers were summarized back to them before moving on to the next question. Interviewees can introduce bias if they do not like the interviewer or if they phrase the answers to be biased towards what they think the interviewer wants to hear. Since the interviewees were obtained through referrals, it is highly unlikely that they gave false responses. Also, the basic area of research was discussed with the interviewees, but no hypothesis was advance to them, such that they would skew their answers to what they though the interviewer wanted to hear.Three companies were interviewed and asked a specific set of questions (see Appendix). There are numerous reasons to interview three companies in Saudi Arabia. These are the following:*The M&A in Saudi Arabia are normally carried out by large size companies.*It is difficult to reach out to the senior managers to discuss such issues.*The officers are also tied by company confidentiality rules to not divulge information.*The number of M&A is also significantly less in comparison with other countries.*The researchers, using diverse resources including personal contacts and formal requests, were able to reach out to three of the major companies of the Kingdom.An interview was conducted with National Commercial Bank (NCB) NCB is an international bank headquartered in Saudi Arabia and engaged in personal, business and private banking, and wealth management (NCB, 2011 ). Another interview was done with Samba Financial Group. Samba is also an international bank headquartered in Saudi Arabia that is engaged in personal and business banking (Samba, 2011). The third company that was interviewed was Savola Holding Company, which is headquartered in Jeddah, Saudi Arabia and is engaged in the food industry. Through subsidiary companies, Savola is engaged in the manufacturing of vegetable oils, dairy products and food retailing operations both in Saudi Arabia and other international markets. Due to strict confidentiality of the companies interviewed, the names of the people will not be mentioned or their titles. This was the most important condition in order to conduct these interviews.Each of the three companies has been involved in significant mergers. NCB's most significant merger was when it acquired a Turkish bank, Turkiye Finans Katilm Bank in 2008.Samba's most significant merger was its acquisition of Cairo Bank in 1 999. Savola's most significant acquisition was its acquisition of Al-Marai in 1 991.NCB has engaged in four mergers overall and three international mergers. In addition to its acquisition of the Turkish bank, it acquired Estate Capital Holdings, The Capital Partnership Group Limited and NCB Capital. The acquisition oftheTurkish bank was considered its most successful acquisition because it allowed NCB to expand into a new international market with strong growth.While NCB does not consider any of its acquisitions to be a failure, it has recognized losses through goodwill impairment, even in the Turkish bank acquisition. Samba's most prominent M8<A has been with Cairo bank of Egypt.Savola has engaged in about 10 mergers including a few international mergers. It considers its acquisition of Panda (a supermarket chain) in 1998 to be its most successful because it allowed Savola to gain a major presence in the food retailing market and increases revenues significantly. Savola has had a couple of mergers that it considered to be failures. One such example was when it acquired a real estate company in Jordan. This company was outside Savola's core business and outside its home country. Savola's learning from this failure was not to invest outside its core business in a foreign country as there was no ability to create any value through this merger and it was investing in a country that it did not know as well as its home country. Another failed merger occurred when it acquired an edible oil company in Kazakhstan. This merger failed because even though the acquired company had good fundamentals, the value creation mechanisms were quite different between the two companies.Strategic motivations for mergers were discussed with the companies and Samba provided details. One motivation is to increase lines of business. Another motivation is to move into a new geographic area. In many cases when expanding into a new country, it is easier to acquire an existing business than try to start a new one. Another motivation is to increase market share.Particularly in a mature industry, a company can gain market share quickly through an acquisition, while it is usually a slow process to gain market share organically in an incremental manner.All the companies tried to achieve company growth and synergy in their mergers.The criteria and selection process for mergers were also discussed with the companies. Savola worked with financial institutions to identify acquisition target companies. Savola looked for companies that were among the leaders in their respective markets. Savola believed that companies that were leaders generally had good processes and were well managed, so their operations would be good to acquire. After the failed merger with the real estate company, Savola looked to acquire companies related to its core food manufacturing and sales business. All companies obviously reviewed financial statements closely to assess the financial condition of the acquired firm. Samba noted that sometimes in the banking and financial industry, strong banks will acquire banks that are in a weak financial condition in a rescue operation, often due to political reasons. In reviewing candidates for a merger, Savola engages its operations and technical team to assess the target company's operation, processes and potential fit into the business group.The three interviewed companies use various metrics to evaluate the success of the merger. Savola evaluates the revenue growth of the sector where the acquisition occurred along with the market share and operating cost. The goals are to increase revenue,increase market share or reduce operating cost. Samba evaluated similar metrics of market share and operating cost.Samba noted that it usually takes until the second year after a merger to evaluateits success. In the first year, there are onetime costs associated with integration costs of the merger. It usually takes until the second year to see reduced operating costs from activities such as closing and consolidating branches.The different ways to obtain synergy in a merger were discussed with the companies. Savola looked to obtain synergy through economies of scale, as acquisitions would add to the company's shipment volume, which would allow the company to reduce freight and distribution costs. Samba also looked to obtain synergy through economies of scale and eliminating the duplication of activities. When it acquired Cairo bank, which had previously acquired United Saudi Commercial Bank, Samba was able to cut costs in Saudi Arabia by reducing the number of bank branches and ATMs. NCB was able to gain financial synergies in its mergers by developing a more diversified and lower risk portfolio ofinvestments.From the responses to the questions included in the structured interview, thefollowing findings can be highlighted:A.Mergers to Expand to International Markets:One finding is that firms undertake some mergers to expand into new international markets. In doing so they are gaining the synergy of the acquired firm's knowledge of the market. In these cases, the acquiring firm saves the costs of starting up a business in the new country, gaining the necessary approvals, learning how to do business successfully in the market and building a brand in the country. This is especially true in the bank and finance industry, where the industry is closely regulated. It can be easier to acquire a company that already has all of the necessary regulatory approvals as opposed to trying to gain all of the necessary approvals to conduct business legally in the selected market. Also, building a brand is important in the banking industry, as consumers and commercial customers prefer to do business with a trusted firm. In these mergers, synergy can be gained through the acquired firm's knowledge of the market and the acquiring firm's capital. The new infusion of capital can often allow the acquired firm to grow in the market. The NCB acquisition of the Turkish bank is a good example of this type of synergy.Even when a firm acquires a company within their own market there is the chance to create synergies through knowledge gained and transferred. In many cases, the acquired firm has certain processes in some areas that are better than the acquiring firm, so selecting the best process allows the merged firm to improve its overall processes. Also, the acquiring company usually has some processes that are better than the acquired firm's processes in some areas, which allows the company to improve the newly acquired operations. As noted by Samba in its interview, the goal is to utilize the optimum processes from both companies to produce synergy from the merger.B.Mergers to Gain Economies of Scale:Firms also seek and gain synergies through economies of scale. Larger businesses can often gain economies in certain business activities including manufacturing, distribution and sales. One of the goals of Samba's mergers was to gain synergies through economies of scale. In their mergers, Savola hoped to gain economies of scale in shipping and distribution activities. Economies of scale can also be achieved in the banking industry since the cost of processing checks or issuing credit cards is likely to decline on a per unit basis with increasing volume; therefore the fixed cost associated with these activities can be spread over a larger volume. The result is reduced costs, which makes the merged firm more profitable and more competitive in the market.C.Eliminating Inefficiencies:Another way to achieve synergy is through elimination of inefficiencies. Removing the duplication of resources can eliminate inefficiencies. In horizontal mergers, it is common for the merged company to consolidate operations, close offices and reduce staff. Samba mentioned that reducing the number of bank branches, ATMs and staff was one of the ways that they drove cost efficiencies after acquiring Cairo Bank. Samba also provided the insight that there is a delay for these cost efficiencies to show up in financial performance, since it takes time to remove the duplication of resources involved and there are one-time costs associated with removing the duplication of resources. The official also pointed out that the success or failure of a merger should not be evaluated until at least two years after the merger.D.Gain More Market Power:Firms also try to achieve synergies through an increase in market power, by controlling a larger share of the market. Discussions with all respondents implied increasing market share to be one of the motivations to enter into a merger. Savola and Samba both mentioned increasing market share as a way to judge the success of a merger. Greater market power can improve profitability through a couple of mechanisms. One such mechanism is greater monopoly pricing power in the market, which allows firms to increase prices due to reduced competition. This is one reason that major mergers have to be approved by government regulators who s objective is to maintain a competitive market. A second mechanism is increased buyer power over suppliers. Since the merged firm represents a greater portion of an industry's business, suppliers to the industry want the merged firm's business more, which gives the merged firm better negotiating power over suppliers. This allows the merged firm to reduce its costs and increase it profits. However, a strategic perspective could be on the supplier side as Porter (1 998) identifies that the stronger the company becomes the weaker the supplier becomes thus reducing their bargaining power.E.Gain Growth:Growth is one of the main reasons that firms undertake mergers, as this was mentioned by all of the companies interviewed. Companies seek growth through mergers because it can allow them to gain market power, which generally leads to increased profits. Mergers are also a way to satisfy investors'/shareholders' expectations for growth. In many cases, itis difficult to grow a business in a mature market organically, so mergers are often the best way to achieve growth.Samba provided a perspective on the use of acquisitions as a growth strategy. Samba believed that within the same industry organic growth was less expensive than growth through acquisition because a premium had to be paid for another company's operations in the same industry. Samba believed that when trying to expand into a different industry, growth through acquisition was less expensive than organic growth because the firm had no knowledge or expertise in the new industry. Samba used this philosophy when formulating their strategic growth plans. If the company simply wanted to expand within their current industry, the focus would be on organic growth initiatives, whereas if the company wanted to grow by expanding into new industries, the focus would be on acquisitions.F.Reducing RisksFirms can gain synergies by reducing their overall risk through diversification and reducing their cost of capital. Generally, this is a weak form of synergy and prone to failures because it often entails firms moving into businesses outside of their core competencies. The businesses are then run without the knowledge of how to run a business successfully in that market. This leads to operational losses or subpar performance in the industry, which negates any synergistic gains from reducing the company's overall risk.This was experienced by Savola, who acquired a real estate company, which was outside its core business of the food market. Consequently, the acquired real estate business produced subpar performance and losses, which negated any gains from reducing risk. Thus, the merger was considered to be a failure because it reduced the overall value of the firm. Due to the difficulties of creating financial synergies through diversification, there are few conglomerate mergers and few conglomerate companies.The companies interviewed look for synergies when considering mergers and try to estimate the potential synergistic gains that could be attained in a proposed merger. The potential synergies gained depend on the industry and the characteristics of the company acquired. In the failed mergers, the firm overestimated the amount of synergy that could be gained through the merger. Savola overestimated the synergy that could be gained through the acquisition of a real estate company because the only synergy that could be gained was。

并购活动的频繁发生使其成为了现代商业中的重要现象。
本文将对并购阶段概况进行文献综述，以探讨并购活动在不同阶段的特点和影响。
一、并购活动的阶段1. 策略规划阶段并购活动通常始于公司的战略规划阶段。
在这个阶段，公司会通过分析市场和竞争环境、评估自身资源和优势，并制定相应的发展战略。
公司会考虑自身的业务领域、市场定位和未来发展方向，从而确定是否需要通过并购来实现战略目标。
2. 目标筛选阶段一旦公司决定通过并购来实现战略目标，下一步就是确定适当的并购目标。
在这个阶段，公司会对潜在的目标公司进行充分的调研和分析，包括财务状况、商业模式、市场地位和管理团队等方面的情况。
公司还会考虑目标公司与自身的业务互补性和整合难度，从而筛选出最适合的并购目标。
3. 谈判阶段一旦确定了并购目标，公司就会开始与目标公司展开谈判。
在谈判阶段，公司需要就价格、交易结构、股权转让和员工待遇等方面与目标公司进行协商。
公司还需要与监管部门和股东进行沟通，确保交易的合规性和顺利性。
4. 尽职调查阶段一旦双方达成初步协议，就需要进行尽职调查。
在这个阶段，公司会对目标公司的全部资产、负债、法律事务和商业情况进行全面的调查和审核。
通过尽职调查，公司可以更全面地了解目标公司的实际情况，规避潜在的风险和问题。
5. 合同签署阶段在完成尽职调查之后，双方可以签署正式的并购协议。
并购协议通常包括交易价格、交易结构、股权转让和员工待遇等方面的内容。
通过签署并购协议，交易正式落实，双方开始筹备后续的交易流程。
6. 政府批准阶段在协议签署之后，公司需要向相关监管部门提交并购申请，并等待政府的批准。
在一些情况下，特别是涉及行业垄断和国家安全的并购案例中，政府可能会对并购进行调查和评估，以确保交易不会对市场和国家利益产生不利影响。

《企业并购中的税务筹划研究国内外文献综述2000字》
企业并购中的税务筹划研究国内外文献综述1.国外研究现状近年来，随着政治、经济、技术等因素，在企业财务规划包括企业财务行为在内的公共利益增长中，促进税务机关对企业纳税活动的进一步沟通，并在国家报告标准中指出税收的不确定性，财务会计准则的建立决定了财务报告与税收优惠之间的权衡之后，国家权利团体反对企业税收筹划的声音，以及媒体决定了企业决策对税收的关注，本文的主要内容和要求是进一步分析税收主动性、决定性因素，许多初步工作集中于各种避税的定义和评价。
Anlon(2013)和McGill(2014)在利用财务报告数据估计或纳税时遇到了困难。
由于公司没有指明税务筹划策略，财务报表中的其他文件会找到开始证明公司税务结构的线索或指纹。
其中一些文件采取步骤来确定逃税活动的法律纠纷(例如，Wilson, 2009)。
2010年Lisowki;brown,2011)。
其他文件关注的是利用账户缺口的激进避税措施。
Desai(2016,2009)制定了针对避税的非正常会计平衡措施。
Frenk, Lynch和Rego(2009)定义了永久性的可自由支配的避税措施来检验逃税意图，战争后研究者也开始使用不确定的利益或税收模式来预测不确定的税收利益。
例如，Leggo 和Wilson在未来的研究中，作为财务规划的代理人，使用避税或其他激进的避税形式。
Hanon(2010)在优秀的税务调查中提供了对这项工作的宝贵整理，其中各种避税措施是恼人的。
Dyreng Hanlon,Maydew(2008)是这方面需要关注的研究。
他们制定长期税率来避税。
与公司财务报告中传统GAAP的有效税率相比，它不影响利润的计算，这是一种有趣的评价方法。
同样重要的是，黄金的有效税率反映了各种形式的避税。
这一措施反映了合法的财政规划，以及更激进、更可疑的财政战略。
长期和暂时的财政储蓄。
扩大税收措施有趣的是，研究人员记录的所得税税负的变化并不局限于税收交易(或法律问题)。
《企业并购的动因和绩效的相关研究文献综述2800字》

Hirshleifer D等（2012）在对银行业数据的进行研究后，得出并购有利于规模经济的形成。
Hobson J A等（1902）的实证研究也支持以Roll为代表人物的自大假说，研究认为媒体对高管的评价情况，以及高管对高薪的追求，都会影响并购中企业支付的对价。
ensen M C等（1976）研究得到，企业之所以进行并购，是因为规模大的企业更容易充分利用资源，从而通过实现协同效应，因此并购有利于成本降低以及协同效应的实现。
Kaplan S N 等（1997）认为，企业进行并购是为了减少与竞争对手的竞争，获得更大的话语权。
Kotz D M（2009）的研究结论认为企业进行并购是为了实现多元化，从而通过企业的业务扩张优化资源配置，最终实现企业绩效的提高。
Krippner G R（2005）研究认为企业进行并购是为了降低交易成本。
Li D 等（2011）等认为，横向并购有利于公司提升整体价值。
Liqun Z, 等（2020）通过研究认为，公司选择进行横向以及纵向整合的一个非常重要的原因是降低企业间的交易成本，以及快速进入新市场。
Lin C等（2009）的研究认为初创公司通过并购实现多元化有助于其快速找到主要发展领域。
（2）短期并购绩效Mario D A等(2013)引入的事件研究方法，这种研究方法的基本思路是分析比较并购事件发生前后相关公司的股票收益情况，判断超额收益是否为正，并购是否创造了累计超额收益，从而通过累计超额收益的情况来衡量并购的短期绩效。
企业并购动因、并购绩效及并购风险文献综述
企业并购动因、并购绩效及并购风险文献综述企业并购动因、并购绩效及并购风险文献综述摘要：本文对企业并购的动因、并购绩效以及并购风险进行了综述。
通过分析相关文献，总结了企业并购的动因包括资源获取与优化、扩大市场份额、提高竞争力、降低成本等；并购绩效主要涵盖财务绩效、市场绩效和战略绩效，并且存在一定的绩效差异因素；同时，企业在并购过程中也面临着多种风险，包括战略风险、操作风险、金融风险和法律风险等。
通过对这些问题的研究，有助于企业更好地进行并购决策和管理。
1. 引言企业并购是指一家企业通过购买其他公司的股权或资产，以实现业务扩张、扩大市场份额、获得技术与资源优势等目标的行为。
近年来，企业并购在全球范围内呈现出快速增长的趋势。
然而，并购活动往往带来各种挑战与风险，因此了解并购的动因、绩效以及风险成为了研究和实践的焦点。
2. 企业并购的动因企业进行并购有多种动因，其中一些是获取资本、技术和资源优势的需要。
首先，通过并购，企业可以获得更多的资本支持，弥补自身发展所需的资金缺口。
其次，通过并购，企业可以获取先进技术和专利，提升自身的创新能力和竞争力。
此外，并购还可以帮助企业获取战略性资源，如市场份额、品牌价值、供应链等，进而实现经济规模的扩大和运营效率的提高。
具体来说，企业并购的动因包括资源获取与优化、扩大市场份额、提高竞争力、降低成本等。
在资源获取与优化方面，企业通过并购可以获得关键技术、人才、渠道和品牌等资源，从而提升自身的核心竞争力。
扩大市场份额是企业通过并购获取更多的市场份额和客户资源，实现业务扩张和销售增长的重要动因。
提高竞争力方面，企业通过并购可以整合供应链、拓展市场渠道，从而获得更强的市场竞争力。
降低成本则是企业通过并购实现规模经济、降低采购成本和生产成本等，提升自身的运营效率和利润率。
3. 企业并购的绩效并购绩效是衡量企业并购成果的重要指标，主要包括财务绩效、市场绩效和战略绩效等。
财务绩效是指企业并购后的财务状况和经营能力的改善情况，如营业收入、净利润、资产回报率等。

但是经过研究，学者们发现企业并购动因的影响因素多种多样，难以归纳成一个确定概念。
就算是一家企业，在不同时间进行并购的目的也是有差异的。
Halil Kiymazh和TarunK.Mukherjee(2000)[1]通过对并购公司进行问卷调查，结果显示大部分公司为获得正的协同效应，增加股东利益而选择并购。
Kode,Ford等(2003)[2]认为企业发起并购也可能是想降低风险。
由于并购后被并购方的投资机会及融资由外转内，企业的融资成本风险会减小。
而Capron(1999)[3]通过研究得到了另一种结论，他们认为企业并购的动因在于取长补短，进而提高企业价值，也使企业在市场中的份额及地位提高。
Heaton(2002)[4]使用了一个简单模型，分析指出：当公司的决策者过于自信，会认为资本市场对本公司的股价低估了，或者高估项目的收益。
在情况一下，当必须用发行股票来进行融资，决策者会放弃净现值为正的投资项目。
在情况二下，会导致决策者其投资于净现值为负的项目。
国内外企业并购研究文献综述
国内外企业并购研究文献综述近年来，国内外企业并购成为了全球经济领域中的一种重要趋势。
企业并购是指两个或多个公司通过合并或收购来达到资源整合和企业集中的目的。
这种方式可以帮助企业实现规模效益、进一步扩大市场份额、获取新技术和资源等。
企业并购研究的文献综述，可以为我们提供对于这一话题的深入理解，并为未来的研究和实践提供指导。
首先，国内外的研究文献就企业并购的动因进行了广泛的探讨。
Wernerfelt(1984)认为，企业并购的动因主要包括资源获得、市场拓展和技术学习等。
此外，Datta等(1992)提出了企业并购的实施路径，包括同业竞争、新技术入侵和产业逆境等。
对于企业并购的动因研究，可以帮助企业更好地理解并购的目的和动机，从而更好地制定并购策略。
其次，国内外研究文献对于企业并购的影响进行了深入的分析。
Khanna和Yafeh(2024)的研究表明，企业并购可以促进企业绩效的提高和盈利能力的增加。
并且，通过并购可以提高企业的创新能力和竞争力，从而进一步提高企业的市场地位。
此外，Kruse等人(2024)的研究发现，企业并购还可以降低企业的运营成本和提高生产效率。
这些研究结果为企业在进行并购决策时提供了重要的理论依据。
此外，国内外研究文献还对企业并购的风险与挑战进行了详细的讨论。
企业并购的失败可能导致企业财务困境、管理混乱和员工流失等问题。
Seth et al. (2024)的研究发现，文化冲突、组织整合和信息不对称等因素是企业并购失败的主要原因。
此外，Brouthers等人(2024)的研究指出，政治因素、法律环境和经济不确定性等也是企业并购面临的风险和挑战。
对于并购风险与挑战的研究，可以帮助企业更好地评估并购交易的潜在风险，并采取相应的措施来降低风险。
最后，国内外的研究文献对于企业并购的影响因素进行了分析。
企业并购涉及到许多因素，如企业规模、技术水平、行业竞争程度等。
Malmendier和Tate(2024)的研究发现，企业文化和管理团队的素质也对并购的成功与否起到重要作用。
企业购并_文献综述和案例
邮发代号８２－３８７ ２００５年第２２期（半月刊） 总第２５１期63企业购并：文献综述和案例文／张志伟一、企业购并理论的文献综述企业购并包括任何一项由两个或更多个实体形成一个经济单位的交易。
购并分为几种不同的方式：横向型购并涉及到两个从事同类业务活动的企业；纵向型购并涉及到某项生产活动的不同阶段；混合型购并涉及到从事不相关类型经营活动的企业。
混合型购并又分为三种类型：产品扩张型购并拓宽了企业的生产线；市场扩张型购并涉及到在不重叠的地理区域内从事经营的两个企业；纯粹混合购并则涉及到既不能被认为是产品扩张型，又不能被认为是市场扩张型购并的不相关的经营活动。
目前，人们已经提出了许多理论来解释为什么购并与其他形式的资产重组活动会发生。
表１对购并活动的各种解释进行了归纳。
效率理论暗含了购并活动除了能给参加者带来收益外，还能带来社会效益。
“差别效率”理论表明效率高的企业将收购效率低的企业，并且通过提高其效率来实现收益，这意味着收购企业中有额外的管理能力。
差别效率最有可能成为相关行业中企业间购并活动的一个要素，因为在相关行业中可以更容易地觉察出改进管理的需要。
“无效率的管理者”理论认为，目标企业的管理者太不称职，以至于任何管理者都可以做得更好，因此，其可以用来解释不相关行业中企业间的购并活动。
该理论的主要局限性在于代理成本太高，以至于如果不通过代价高昂的购并，股东便无法惩戒管理者的看法。
“经营协同”理论假设存在规模经济并且收购有助于达到可以获得规模经济的活动水平，它包含了能力互补性的概念。
例如，一个企业可能在研究与开发方面有较强的实力，但在市场营销方面实力较弱，而另一个企业的市场营销部门可能有很强的实力，但缺乏研究与开发方面的能力。
这两个企业的购并将导致经营上的协同。
“财务协同”理论认为，购并的两个企业间的互补性不是管理能力方面的，而是在投资机会和内部现金流量方面的互补性。
一个衰退行业内的企业将产生大量的现金流量，因为其有吸引力的投资机会很少，而一个成长的行业有很多投资机会，以至于没有足够的现金来进行投资。
《企业连续并购问题研究国内外文献综述3600字》
企业连续并购问题研究国内外文献综述一、国外研究现状关于企业并购的相关文献研究，西方国家距今已有着多年历史，并取得了较为全面且具体的研究成果，也随之产生了相对完善的企业并购融资体系。
它包括不同的金融并购融资中介机构、金融工具和管理体系。
在并购融资理论方面，西方还形成了丰富完备的并购融资理论，且取得了较为丰硕的成果。
1983年，Schipper 和Thompson第一次提出了连续并购的概念，Schipper 和Thompson将其定意思为“企业在三年期间内发生三次及三次机上的并购交易”。
在此之后，也有国外研究学者将连续并购分类为短时间内的连续并购与长时间内的连续并购。
前者指的是企业在3-5年内发生不少于5次的并购交易，后者指的是企业每年发生1-2次的并购交易。
Doukas和Petmezas（2007）以及Billett和Qian（2008）发现证据表明，过分自信的高管倾向于进行连续收购，因为他们认为，与“理性”高管相比，这样的连续投资决策最符合股东的利益。
由于过度自信的高管认为他们比别人具有更强的能力。
这种认知偏差激励他们对自己的判断力和从事复杂的任务进行下注，例如连续收购。
过度自信会促使高管人员在企业并购管理中将会明显低估并购风险，高估并购产生的协同作用，因此过度自行的高管可以很乐观并且倾向于快速收购和频繁地定位收购目标。
Croci 和Petmezas（2009）以美国1990年至2002年发生连续并购的591个公司为样本，检验了连续并购的四种潜在动机，即管理层过度自信，卓越收购管理技能，管理者帝国构建动机以及收购是否包含单一计划。
研究发现，成功的收购后续也往往伴随着成功的收购。
这种表现的持久性表明，出色的管理技能可能是进行连续收购的重要原因。
过度自信不会驱使胜利者的连续并购，管理者帝国构建动机也不会驱使连续并购，连续并购也不是并购公司整个收购计划的结果，只有管理层卓越的收购管理技能促使了公司连续并购活动。
并购阶段概况的文献综述
并购阶段概况的文献综述引言并购是指公司之间的联合和整合，以便获得更大的市场份额，降低成本，提高效率，并实现更高的盈利。
并购活动在企业发展战略中起着至关重要的作用，不仅可以扩大企业规模，还可以实现资源整合，提高市场竞争力。
本文将对并购阶段的概况进行文献综述，进一步分析并购的相关理论和实践，为相关研究和实践提供参考。
一、并购的概念及分类并购是指一个公司或者机构收购另一个公司或者机构的股票、资产或者经营权，并将其合并到已有的企业当中。
根据并购目的的不同，可以将并购分为战略性并购和财务性并购两种。
战略性并购是指企业为了实现市场扩张、资源整合或者技术提升等目标而进行的并购活动；财务性并购则是指企业为了获取财务回报而进行的并购活动，通常是为了实现规模经济或者降低成本等目标。
二、并购阶段的概述并购活动通常包括策略规划、目标筛选、交易洽谈、尽职调查、合同签署、财务融资、监管审批、并购整合等多个阶段。
在策略规划阶段，企业需要明确并购的目标和动机，以及合并后的预期效果；目标筛选阶段则是确定合并对象，并对其进行综合评估；交易洽谈阶段则是双方就合并条款和条件进行协商；尽职调查阶段则是对目标公司的财务、法律、经营等情况进行详细审查；合同签署阶段是双方就合并协议进行最终的确认和签署；财务融资阶段是为并购交易筹集必要的资金；监管审批阶段则是向监管机构提交相关申请，并取得批准；并购整合阶段是将合并后的企业进行业务整合和管理整合。
三、并购阶段的理论分析在以上并购阶段中，相关学者提出了许多理论来解释并购活动的影响因素和机制。
资源依赖理论认为，企业进行并购是为了获取和整合外部资源，以实现规模经济和市场优势；机会成本理论则认为，并购活动可以减少企业的机会成本，提高企业的市场竞争力；整合成本理论则强调了并购活动可能带来的管理整合和文化整合问题，以及由此可能产生的成本。
这些理论为我们理解并购活动提供了重要的思路和框架，同时也为相关实践提供了指导和启示。
企业并购动因、并购绩效及并购风险文献综述共3篇
企业并购动因、并购绩效及并购风险文献综述共3篇企业并购动因、并购绩效及并购风险文献综述1企业并购动因、并购绩效及并购风险文献综述企业并购是指一家企业通过收购或兼并其他企业，以实现自身发展战略目标的行为。
随着全球化和市场竞争的日益加剧，企业并购的频率和规模都在不断增加。
在大多数情况下，企业并购被视为一种快速扩大市场份额、加强产品或服务线以及提高企业利润的有效途径。
本文将从企业并购动因、并购绩效以及并购风险三个角度来探讨企业并购的相关文献。
一、企业并购动因企业并购的动因多种多样，包括战略、财务、组织和人力资源等因素。
战略因素是企业实现业务和市场目标的关键因素之一。
例如，一个企业可以通过并购来扩大市场份额、进入新市场和增加产品和服务线。
财务因素也是企业并购的重要动因之一。
结束以确保企业经济效益的最大化。
另外，企业并购的组织和人力资源因素也很重要。
例如，企业可以通过并购获得更多的员工、技术和知识产权等，从而提高组织的运营效率。
二、并购绩效企业并购绩效是评估企业并购战略成功或失败的重要指标。
并购绩效可以通过很多方面来衡量，其中包括财务、市场份额、员工满意度和产品创新等。
财务绩效是评估企业并购成功与否的重要标志。
良好的财务绩效，不仅可以提高企业的市场竞争力，还可以吸引更多的投资者和融资机构。
此外，并购还可以提高企业的市场份额和提高员工的生产率和满意度。
最后，企业并购还可以通过增加产品和服务线来获得创新和竞争优势。
三、并购风险企业并购不仅存在机会，还存在诸多的风险。
企业并购的风险包括财务、运营、人力资源和战略等。
其中财务风险是企业并购面临的最大风险之一。
企业并购需要大量的财务资金，如果企业无法获得足够的投资，企业并购可能会失败。
运营风险是企业并购过程中另一个重要的风险。
企业并购需要协调不同的业务和组织，如生产、销售和市场等。
人力资源风险也是企业并购过程中的主要风险之一。
企业并购需要吸引和留住大量的员工，企业需要制定明确的人力资源政策和制度来保证员工的稳定性和忠诚度。

其中兼并（Merger）含有吸收合并、吞并之意，是指具有优势地位的企业吸收吞并另外一家或多家企业，获取目标公司的控制权并使其丧失法人资格的行为。
《国际财务报告准则第3号-企业合并》指出1，收购（Acquisition）则是指一家企业，即购买方支付对价购买另一方企业的股票或资产，以获得对该企业资产的所有权，或对该企业的控制权的行为。
总的来说，并购是指一家企业通过单次或分阶段运作，以获得其他企业控制权的经济活动。
根据并购双方在业务种类与市场地位方面的联系，并购可以分类为横向并购、纵向并购与混合并购。
其中，横向并购目的在于追求规模效应、扩大市场份额、提升企业行业地位等，并购双方往往有着相似的主营业务产品或服务；纵向并购的并购双方多位于同一产业链的上下游，彼此之间关系与联系密切，纵向并购的目的往往在于完善产业链、形成行业壁垒；混合并购则是指很少有业务或服务联系的企业之间的并购活动，可以帮助企业进入新行业，实现企业产品与服务的多样化。

关于国内外对企业并购动因研究的文献综述
胡云枫M01114234
摘要：20世纪以来，并购已经成为企业快速扩张和整合的重要手段之一。
为了探究企业并购的动因，国内外学者从不同角度做了大量研究。
本文对有关国内外企业并购的动因研究的文献做了总结与综述。
关键词：企业并购动因文献综述
一、国外对企业并购动因的研究
企业并购动因理论解释促成企业并购发生的影响因素。
1. 经营协同假说( operming synergy hypothesis)
该假说假定存在着规模经济, 并且在并购之前, 企业的经营活动达不到实现规模经济的潜在要求, 包括横向降低成本费用的生产规模经济、纵向降低交易费用的规模经济和特定管理职能方面的规模经济。
通过并购可以对企业规模进行扩充和调整, 达到最佳规模经济或范围经济, 这可能是对企业并购最经典的经济学答案。
2. 管理协同假说( management synergy hypothesis)
该假说认为优势企业并购劣势企业, 管理者作为一个团队被转移时, 能够将被收购公司的非效率性的组织资本与收购公司过剩的管理资本结合从而产生较好的协同效应。
3. 财务协同假说( finance synergy hypothesis)
该假说认为并购是将目标企业所在行业中的投资机会内部化, 将企业外部融资转化为内部融资, 由于内部融资比外部融资成本更低, 从而增加了财务协同,降低了融资风险。
4. 市场力量假说( market power hypothesis)
认为公司间的并购可以增加对市场的控制力。
首先, 通过并购同行业企业, 以减少竞争者, 扩大了优势企业的规模, 优势企业增加了对市场的控制能力, 从而导致市场垄断。
其次, 即使不形成垄断, 由于并购扩大的规模效应也将成为市场进入的壁垒。
5. 战略动机假说( strategy motive hypothesis)
企业并购战略动机在于通过并购活动实现多样化经营,企业并购可以通过实
现业务多样化, 降低经营风险, 保护组织资本和声誉资本。
企业并购战略动机另外还可以通过外部获得目标企业的现成资源。
Porter 认为纵向并购, 收购方公司保证了关键资源的投入, 降低了外部的不确定性,获取被收购公司的技术优势或知识资本实证研究表明, 并购加速了新技术的扩散和转移; 当企业跨国扩张不具有人力资源优势时, 通过并购获得目标公司的人力资源来实现成长。
6. 控制权市场假说( corporate control market)
认为经理们对公司的控制权的争夺, 收购了公司就获得了控制该公司、经营该公司资源的权利。
该假说有三个联系的命题: 其一, 企业并购的动机在于获得控制权增效。
其二,控制权增效分为事前增效和事后增效, 其中，事前增效是在控制权获得之前对效率改进和价值增大效果所作的评估;事后增效是在控制权取得之后对效率改进和价值增大所得到的效果。
两者比较决定着并购的成败。
其三, 控制权增效对整个经济的效率改进有可能带来积极影响, 也可能带来消极影响。
由于经营不善的企业很容易受到外部收购的威胁, 经营不善的管理层就有被替换的危险, 当目标公司出现代理问题时, 通过并购获得控制权, 可减少和弱化代理问题。
这是企业并购动机对解决代理问题提供的一个答案, 即当报酬安排、监督、经理人市场、资本市场等内外机制都不能解决代理问题时, 并购就成为解决目标企业代理问题的途径, 它可以减缓所有权与控制权相分离所带来的代理问题。
二、国内对企业并购动因的研究
“消除亏损说”认为企业并购是消除亏损的一种机制, 通过并购机制加大亏损企业的经营压力, 使其努力提高经营效率;
“破产替代说”认为并购是一种破产替代机制, 由于我国承受不了大规模的企业破产, 特别是大规模的国有企业破产,对于大多数亏损企业, 通过并购以好带差, 带动劣势企业的发展。
仍然要从改革和稳定的大局出发, 给予救助, 而不是轻易让其破产;
“利用优惠政策说”认为, 我国政府为鼓励企业并购, 制定了许多财税、信贷方面的优惠政策, 一些企业出于利用这些优惠政策进行企业并购;
“强壮民族工业说”认为强强联合式的企业并购实际上是强壮民族工业的需要。
面对外资以其资本实力上的竞争优势对我国民族工业的攻势, 我国民族工业
只有实行强强联合, 组成能与国际跨国公司相抗衡的“国家队”, 才能在日益激烈的国际竞争中求得生存和发展;
“资源优化配置说”认为, 通过并购实现国有资产在不同所有制之间、不同地区之间、不同产业之间的流动, 有利于盘活国有资产存量, 实现资源优化配置, 提高资源使用效率。
以上通过比较西方的企业并购动机理论和具有中国特色的企业并购动机理论, 从中可以看出中国向市场经济过渡时期的企业并购的特点: 我国并购的动机不仅仅来自于企业内部, 它还来自于政府部门, 甚至有时政府的动机强于企业本身, 政府的推动力在中国企业并购中起了相当重要的作用。
我们也注意到, 随着我国市场经济的发展, 企业行为也日益走向规范, 在并购行为上也越来越多地考虑一些有关自身长远发展的战略问题。
魏江( 2002) 对多家企业的并购的调查, 认为我国并购的直接动机有以下几类情况: 完全的政府推动, 企业处于被动状态; 获取资源要素, 最重要的是土地资源;企业构筑企业集团, 实现扩张的需要, 如生产能力的扩张; 获得优惠政策和合理避税; 长远发展考虑, 如规模经济或范围经济, 或为了获取市场机会。
蔡宁等( 2002) 将我国企业并购动因归纳为追求规模经济、扩展市场势力、取得关键要素、多元化经营、管理者动机和获取直接的经济利益, 并通过与美国企业并购案例进行比较分析, 认为我国的一些优势企业也开始从提高规模效益、扩大市场势力、实现企业低成本扩张等动机出发来实施并购战略。
张新( 2003) 研究认为, 西方的经典并购动机( 协调效应、狂妄假说和代理动机) 理论对我国企业并购有一定的解释力, 并就经典并购动机对中西方市场的解释程度进行了比较, 提出了我国经济转轨条件下的体制因素下的价值转移与再分配0的并购动机假说。
可见, 我国的企业并购已经是一种适应日益激烈的竞争需要的企业长远发展机制, 西方比较成熟的企业并购动机理论开始适用于中国。
