摘要

人均国内生产总值（Real GDP per capita），也称作“人均GDP"，常作为发展经济学中衡量经济发展状况的指标，是重要的宏观经济指标之一，它是人们了解和把握一个国家或地区的宏观经济运行状况的有效工具。将一个国家核算期内（通常是一年）实现的国内生产总值与这个国家的常住人口（目前使用户籍人口）相比进行计算，得到人均国内生产总值。是衡量各国人民生活水平的一个标准，为了更加客观的衡量，经常与购买力平价结合。

本文依据1978–2008年我国人均消费和人均国内生产总值和2003年各地区人均国内生产总值和对外开放水平的相关数据,运用相关知识,对我国人均消费和人均国内生产总值关系、分布地区及对外水平和人均国内生产总值关系进行检验。

首先应用从《中国统计年鉴》收集的1987–2008年我国人均国内生产总值的数据，利用MATLAB软件求出其数字特征，根据求出的数据特征进行分析；再利用MATLAB软件绘制曲线图，根据图形分析其变化趋势。

其次应用所搜集的2003年各地区的统计数据，应用MATLAB软件进行数据拟合，直观的展现变量之间的关系。

The per capita gross domestic product (Real GDP per capita), also known as the "GDP" per capita, often in development economics as a measure of economic performance index, is one of the important macroeconomic indicators, it is an effective tool to understand and grasp the situation of macro economy of a country or region's people. A national accounting period (usually a year) to achieve the GDP and the country's resident population (currently used household population) compared to calculate, get the per capita gdp. Is a standard to measure the standard of living of the people of various countries, in order to measure more objective, often combined with the purchasing power parity.

Based on the relevant data of the per capita GDP in 1978 - 2008 China's per capita consumption and per capita GDP in 2003 and the various regions and the level of opening up, using the related knowledge, to examine China's per capita consumption and distribution of per capita GDP, area and level of foreign trade and GDP per capita relationship.

The first application from the "China Statistical Yearbook" collection of 1987 - 2008 China's per capita GDP data, calculate the numerical characteristics by using the MATLAB software, according to the analysis of data characteristics calculated; then we use MATLAB software to draw curves, based on the graphic analysis of its changing trend.

The statistical data collected in 2003 followed by application area, application of MATLAB software for data fitting, reveal the relationship between variables.
