中国城乡收入差距:扩大还是缩小?

China's Urban-rural Income Gap:Growing or Shrinking?

基于产出的资本所得由城镇人口所有的假设和新古典经济增长理论的框架,构建中国城乡人均收入差距模型,分析表明:随着城市化率的提高,城乡人均收入差距倍数会逐渐缩小;经济中资本所得份额越大,城乡人均收入差距倍数就越大;农村劳动力向城镇流动将减少城乡人均收入差距。在社会主义市场经济框架下,随着劳动力全国范围内的自由流动,无论是理论模型及其推论还是实证检验结果都表明我国城乡收入差距并非扩大而是逐步缩小。

Under the assumption that urban residents enjoy income from forms of capital return and based on neo-classical economic growth theory framework,this paper constructed the model of per capita income gap between urban and rural area,the analysis shows that,with the rising of urbanization rate,the multiple of urban-rural per capita income gap will gradually shrink,the bigger the share of capital return is,the bigger the multiple of urban-rural per capita income gap is,that the flowing of rural labor from rural to urban area will decrease urban-rural per capita income gap.Under socialism market economy framework,with free nationwide flowing of labors,both theoretical model and its deduction or empirical test results indicate that China＇s income gap between urban and rural area is not enlarged but gradually shrinks.
