公共服务与城镇化质量的关联测度

Measurement of the Relationship between Public Service and Quality of Urbanization

随着经济体制改革的持续深化，中国经济已步入新常态时期，如何辨识公共服务与新型城镇化发展的关联性成为一个重大的现实课题。文章构建了公共服务与城镇化质量的初始理论模型，借助公共服务基本指标体系，采用全局主成分分析法考察了大陆地区31个省、市、自治区的城镇化质量。通过建构回归面板模型探讨城镇化质量对城镇化进程和经济效益的关联影响，研究发现：在2005～2014年间，以公共服务为评价指标的城镇化质量呈现出东、中、西区域的“梯度式”下降趋势，但相邻板块的省、市、自治区却出现逆转之现象；城镇化质量对于城镇化进程及经济效益有着显著的正向关联影响，且滞后的长期效应大于当期效应。为此，文章提出了进一步优化城镇化质量的政策建议，以期促进公共服务供给与新型城镇化质量之间的良性互动。

With the deepening continuous of economic reform,China's economy has entered the New Normal period,how to recognize the relationship between public services and the development of new urbanization has become a major practical issue. The article constructs the initial theoretical model of public services and the quality of urbanization,by means of the basic indicators of public service system,using the global principal component analysis examines the mainland's 31 provinces of the urbanization quality. Meanwhile constructing regression panel model to measure the urbanization has mass-related effect on the process of urbanization and economic benefits. The study found that using the evaluation index of public service to measure the urbanization quality shows a gradient downward trend of eastern,central and western regions from 2005 to 2014 year,but the adjacent plates of provinces,municipalities and autonomous regions shows the reversal phenomenon; the quality of the urbanization has a significant positive impact on process of urbanization and economic benefits,and the lag period has the greater long-term effects than the current period. Therefore,this article presents policy recommendations to further optimize the quality of urbanization,in order to achieve positive interaction with the supply of public service and the new urbanization quality.
