中国地区经济差距演变及其产业分解

The Evolution of Regional Economic Disparities in China and Its Decomposition by Industry

本文借鉴泰尔熵的原理,构造了一个泰尔指数,用以分析中国改革开放以来的地区经济差距问题。研究发现中国地区经济差距已演变为倒"N"型,1990年和2003年是两个拐点。从产业角度看,地区经济差距由产业内差距和产业间差距两部分组成。第二、第三产业的产业内差距是地区经济差距的主体,产业间差距也有不可忽视的影响,各种差距都具有明显的时段性特征。产业增长和产业结构调整影响着地区经济差距如何变化,并且这种影响相当复杂,在各个时期明显不同。但长期看来,地区经济差距变化主要源自产业成长性的不同,产业结构影响微弱,产业结构调整只在短期内对地区经济差距有显著的调节作用。

Drawing on the principles of Theil entropy,This article constructs a Theil index in order to analysis the regional economic disparities in China.The results shows that the regional economic disparities have become the inverted ＂N＂ type in which 1990 and 2003 are two inflection points.From the industrial point of view,regional economic disparities has two contents： disparities within industries and disparities between industries.The disparity within secondary and tertiary industry is the mainstay of regional economic disparities and the disparities between industries which has a clear characteristics of the period also has significant effect.Industrial growth and industrial restructure affect the changes in regional economic disparities and the process are very complexity and obviously different in different periods.However,long-term view,the evolution of regional economic disparities is mainly as a result of the growth of different industries.Industrial restructure play a import role in the changes of regional economic disparities only in the short term.
