泰尔(Theil)指数及其在中国的适用性检验——兼论收入分配与扩大内需

Theil Index and Its Suitability Test in China——the Relationship between Income Distribution and Expanding Domestic Demand

本文把衡量收入差距的泰尔指数引入消费模型,运用中国1992～2010年的相关数据对收入分配和有效需求之间的关系进行实证研究。结果显示:收入分配的变化会严重影响总消费规模和总消费倾向,收入分配差异会严重影响有效需求。收入分配差异和消费支出之间存在着反向的因果关系。内需不足已经成为制约中国经济发展的瓶颈,而由现行收入分配制度所带来的收入差距拉大,则是阻碍中国扩大内需战略实施及经济增长方式转变的根本因素。

This paper builds a consumption mode with the Theil Index, which is a measure of income inequality. Using Chinese related data from 1992 to 2010, the paper analyses the relationship between income distribution and effective demand. The results of empirical study show： Changes in income distribution would seriously affect the size of aggregate consumption expenditure and aggregate consumption propensity, income inequality would seriously affect effective demand There is a reverse of causality between income inequality and consumption expenditure. It can be seen further that insuffi- cient domestic demand has become the bottleneck of restricting China＇s economic development. The increase in income inequality caused by the current income distribution system, has been the the fundamental factor which hinders the implementation of Chinese strategy to expand domestic demand and transformation of economic growth pattern
