国际收入不平等变化的中国因素分析——基于控制人口因素的方法

中国的贡献是国际收入不平等程度从1978年到2000年呈下降趋势的主要动力,在20世纪80和90年代的部分年份中国因素的贡献率超过100%。通过控制人口因素的方法分析揭示,中国经济增长是中国因素变化的主要原因,人口增长是次要原因,但却是重要原因。20世纪80和90年代人口增长对中国因素变化的贡献率在31.8%和43.5%之间波动,经济增长的贡献率在56.5%和68.2%之间波动。所以,虽然中国因素推动国际收入不平等下降的主要源泉是经济增长,但人口增长的作用也非常重要。

China Component in International Income Inequality: Controlling Population Factors Approach

The contribution of China is the main engine for decline of international income inequality in 1980's and 1990's. It is over 100 percent some years. By applying the method of controlling populaion factors, it is revealed that though economic growth is the major reason of change of China component, and population is the minor, but it is important. The contribution of population growth to change of China component fluctuates between 318% and 435% in 1980 and 1990's, and that of economic growth does between 565% and 682%. Therefore, economic growth of China is the main reason, but population growth also plays an important role for decreasing of international income inequality.
