城市规模对流动人口幸福感的影响——来自RUMIC(2009)的经验证据

城市规模对流动人口幸福感影响可谓是一把"双刃剑"。基于RUMIC(2009)微观数据,采用工具变量法系统研究我国城市规模对流动人口幸福感的影响及其传导机制。研究发现,我国城市规模对流动人口幸福感影响效应呈显著的"U型曲线"关系,城市市辖区人口规模约在340万人时,城市规模对流动人口幸福感的影响效应出现拐点。其中,收入是城市规模影响流动人口幸福感的主要传导路径,测算得出,城市规模通过影响个体收入而对流动人口幸福感影响的间接效应约占总效应的64%。同时,城市规模通过提高城市生产率和降低失业率而影响流动人口幸福感的间接效应分别占总效应的6.1%和9%左右。

Urban Scale Influence on the Well-being of Floating Population——Empirical evidence from the RUMIC (2009)

Urban expansion impact on the well-being of the floating population is a "double-edged sword". This paper is based on RUMIC (2009) and uses Instrumental Variable Method to study the influence on the well-being of the floating population and its transmission mechanism. We found that the relationship of the urban scale and the well-being of the floating population is significantly "U" type curve, city municipal district population scale is about 3.4 million people, city scale for the well-being of the floating population effect appeared inflection point. Among them, Income is the main transmission path for urban scale affecting on the well-being of the floating population, city scale by influencing the individual income and indirect effect of impact on the well-being of the floating population accounts for about 64% of the total effect; At the same time, the city scale by increasing productivity and reducing unemployment which might affect the well-being of the floating population accounted for 6.1% of the total effect and indirect effect of about 9%.This article research conclusion is sound, to promote the development of urbanization in our country and safeguard the welfare of the floating population to provide the beneficial enlightenment.
