中国可持续经济福利水平测度及区域差异分析

China’s Sustainable Economic Welfare Measurement and the Analysis of its Regional Differences

随着居民生活水平的提高和中国社会主要矛盾的变化,美好生活和福利问题成为现阶段学术界的研究重点。文章首先采用可持续经济福利指标体系(ISEW)框架,测算了2000—2016年中国31个省(区、市)的福利水平,结果表明,中国可持续经济福利水平呈现显著的增长趋势,特别是在2008年之后增长更快,同时各地区之间增长速度差异也越发明显。然后采用Dagum基尼系数,从区域内、区域间、超变密度三方面对可持续经济福利区域差异进行分解,结果表明:中国可持续经济福利总体差异呈现"U"形变化,区域内差异呈现东→西→中→东北递减趋势;东部地区与西部地区之间的差异最大;对总体差异影响最主要的因素是区域内差异,其次为区域间差异。最后提出了提升可持续经济福利水平的政策建议。

With the improvement of people’s livelihood and the change of China’s main contradiction,the issue of a better life and welfare has become the focus of the academia.This paper,firstly,measures the welfare of the 31 provinces in China from the year2000 to 2016 by adopting the framework of index for sustainable economic welfare(ISEW),which shows China’s sustainable economic welfare demonstrates a significant increasing trend,increasing especially faster after 2008,and at the meantime,the differences of the increasing rates among different regions become more pronounced.Then,this paper decomposes the regional differences of the sustainable economic welfare in such three aspects as intra-regional,inter-regional and density of transvariation by adopting the Dagum Gini coefficient,which shows that the overall differences of China’s sustainable economic welfare present a Ushaped curve,and the inter-regional differences present a trend to decrease progressively from east to west to middle to northeast;the difference between the east and west is the greatest;the top influencing factor to the overall difference is the inter-regional difference,followed by the intra-regional difference.At last,the paper makes some policy suggestions for improving the sustainable economic welfare.
