An Empirical Study on Urban-Rural Income Gap,Urbanization and Social Security Expenditure in China
基于1997-2011年30个省份的面板数据，研究发现全国层面城镇化和社保支出未能显著缩小城乡收入差距；但半数以上省份的社保支出有缩小作用，且区域效果存在差异。
Based on 1997-2011 panel data model with variable coefficients,an empirical study on urban-rural income gap, urbanization and social security expenditure of the 30 provinces in China has been conducted. The study shows that,for the country as a whole,it is not beneficial for urbanization and social security expenditure to remarkably narrow urban-rural income gap. For the specific provinces,it is not beneficial for urbanization to remarkably narrow urban-rural income gap in most regions,and it is beneficial for social security expenditure of more than half of the provinces to remarkably narrow urban-rural income gap. But the effect of different regions shows some differences. The policy implication is that,through the establishment of regurgitation-feeding mechanism between urban and rural areas and improving the social security system,it can narrow the income gap between urban and rural areas and promote social fairness.
