城市规模对城乡居民收入差距的影响效应研究——基于2000～2010年省际面板数据的实证分析

城市规模和城乡居民收入差距加大,是我国当前区域与城市经济发展的明显特征.在2000～2010年中国31个省际地区城镇居民年人均可支配收入、乡村居民年人均纯收入、城镇人口、乡村人口和地区总人口等指标的基础上,构建包含泰尔指数Theilit和城市规模Lnupsit两个面板数据变量的个体固体效应模型,研究表明,泰尔指数与城市规模变量之间存在长期稳定的协整关系,其影响系数为2.6741％,现行的城市规模扩张总体而言仍不利于缩小城乡居民收入差距.

Research on the Effects of Urban Size on Chinese Urban-rural Income Gap——An Empirical Analysis Based on Chinese Provincial Panel Data from 2000 to 2010

It is an important feature of current regional and urban economic development that city size and urban-rural income gap are increasing.Based on the direct variables of the per capita disposable income of urban residents,per capita net income of rural residents,urban population,rural population and the total population of China’s 31 provincial-level regions from 2000 to 2010,the paper builds an individual solid effect model containing two variables of the Theil index and urban size to analyse the relationship between them,The result shows that they are cointegrated with an influence coefficient of 2.6741%,and the urban expansion is still not conducive to narrow the urban-rural income gap.
