城市化、城市圈与城乡收入差距

运用断点回归方法对京津冀、长三角、珠三角城市圈进行分析,结果表明城市圈之内的地区的城市化水平比城市圈之外的地区高1到2个百分点,而城市圈对农耕面积、教育水平和金融发展水平等可能影响到收入差异的变量没有直接的影响。进一步运用二阶段最小二乘的方法估计由于城市圈形成所导致的城市化水平变化对城乡收入差距的影响,结论是城市化水平的提高缩小了城乡收入差距。城乡二元经济导致的一些制度性的障碍以及城乡金融发展的不平衡是目前城乡收入差距扩大的主要原因,因而应尽快消除阻碍城乡劳动力流动的制度性障碍,并不断完善农村金融体制。

Urbanization, Metropolitan Circle and Urban-Rural Wage Inequality

Regression-discontinuity is used to analyze metropolitan circles of Beijing,Tianjin,Hebei,the Yangtze River Delta and the Pearl River Delta,and the results show that the urbanization level in the areas inside metropolitan circles is 1-2 percent higher than that of the areas outside the metropolitan circles and that the metropolitan circles have no direct impact on the variances influencing wage disparity such as farmland,education level,financial development level and so on.Two-Stage Least Square Estimation...
