有245台,其中大连港进口200t以上的
产品就有45台之多,最大的吨位达到
600t。2004年上半年的进口量由2003年
的93台增加到228台,同比增长145%。
而2004年上半年的国产销售量为107台
(不完全统计),仅占总销售量的32%,
如图7所示。据估计200t以上的工程起

摘要 SUMMARY
6 FEATURES:Investment analysis of 2004 and prospect of 2005
Though more and more active factors have acted on the stable growth of economy, it is difficult to
eliminate thoroughly unreasonable factors in the structure of economy and investment,which accumulatedlong before.Because of the macro control policy,the growth of investment is slow.
How to coordinate the invested relationship of primary,secondary and tertiary industries,how tocontrol the overall invested scope,at the same time,maintain a stable and relatively-fast growth trend,and how to improve the structure of investment.These tasks must be faced in 2005.
Some important opinions in investment and economy prospect of 2005 in China are brought forward according
to analysis on the investment situation of 2004.
14 FEATURES:Further analysis on macro control and forecast of 2005
From the second quarter of 2004,Chinese government took a series of policies to cool down econony,especially limited the investment in fixed assets.But the growth rate of GDP also reaches 9.5%.whichis much higher than established rate of 7%.Although the investment of limited sectors fell down,itcaused the shortage of energy sources.Local governments’booming investment is a reason for this
phenomenon.The existence of civilian capital makes the condition worse.Comparing the current macro
control with that of 1993,we can get the trend of macro policy.Construction machinery is not
controlled,but is affected indirectly.So the macro control will continue in 2005,and the impact on
construction machinery will last at least two years.
28 MARKET:Development of domestic and overseas large cranes
Based on construction requirement,development of domestic and overseas large
cranes used in lifting construction is fast.You can find the cranes of every tonnage class in the market.And the demand of large cranes is increasing.The cranes of light weight,strong loading ability and other
advantages appeared successively.New structures extend the work place.New combinations of arm have come
forth.What is more,some cranes can install and take down all by itself.Automation and electronic
technology have been applied in its control system.And a mixed crane has the advantages of both the crawler
and wheel cranes.In addition,the domestic market of cranes has strong potential.The enterprises ofdomestic capital have made great progress.
46 RENTAL:Cognition can’t be neglected in the field of China rental
September 2001,Leasing Business Committee of China Association of Enterprises with Foreign Investment
organized a group to investigate rental policy in USA and Europe.The cognition to rental becomes more and
more significant with time flying.First,we must distinguish rent,finance lease and operating lease.Secondly,the character of finance lease should be defined clearly.Commodity rental should be the primacy
in finance lease.Thirdly,supervision is another important aspect.Besides,through thinking about the
history of leasing business of enterprises with foreign investment,we can also gain some illumination.
