土地市场二元分割对城乡收入差距的影响

A Study on the Influence of Rural-urban Land Market Segmentation on the Rural-urban Income Gap

对日益突出的我国城乡收入差距问题,有必要从土地市场角度进行量化分析。将土地市场二元分割特征引入一般动态均衡模型来分析其影响城乡收入差距的机理,并运用参数校准和数值模拟来检验城乡二元分割的土地市场和城乡收入差距之间的关系。结果表明:土地市场二元分割是造成城乡收入差距不断扩大的重要因素。广东"南海模式"、"顺德创新实践"、四川"成都城市统筹"等案例佐证了破解土地市场分割对缩小城乡收入差距的作用。伴随着土地市场从二元向一元逐步过渡,城乡收入差距会逐渐缩小。以此为基础,提出相应的政策建议。

China＇s income distribution problem has become increasingly prominent, and there is little lit-erature in the perspective of land market on the quantitative analysis of income gap. A general equilibrium model is constructed to analyze the rural - urban land market segmentation effect on the rural - urban income gap. The relationship between the rural - urban land market segmentation and the rural - urban income gap is tested by using the calibration and numerical simulation. The results of the numerical simulation show that the segmentation of the rural - urban land market expanded the rural - urban income gap, the rural - urban income gap will be greatly reduced if the urban and rural land market are integrated. On this basis, the paper puts for-ward the corresponding policy suggestions.
