中国省际基本公共服务供给效率时空演变分析

The measure and characteristics of spatio-temporal evolution of basic public services supply efficiency in China

基于超效率DEA模型对中国2007—2014年省际基本公共服务供给效率进行测度,并运用探索性空间数据分析方法分析时空格局演变特征.结果表明,2007—2014年我国基本公共服务供给效率整体呈现"U"型演变趋势;省际间绝对和相对差距均呈扩大态势,有类马太效应特征,低效率地区对高效率地区"追赶效应"不显著.基本公共服务供给效率空间格局上不均衡;供给效率全局趋势上东西向自东向西递减,南北向呈倒"U"型格局.全局自相关分析表明我国省际基本公共服务供给效率具有正空间相关性,随时间演进呈现"分散—集聚—分散—集聚"的演变模式;高高集聚区集中于长三角、珠三角等东部地区,低低集聚区集中于西部及东北地区,高低与低高集聚区则集中于两者过渡区域.

Based on the super efficiency DEA model,this paper firstly estimates the provincial supply efficiency of public service in China from2007to2014,then the exploratory spatial data analysis method is used to discuss its characteristics of spatio temporal evolution.Research shows that Chinas basic public service supply efficiency displayed a“U”type evolution trend from the year2007to2014.Both absolute gap and relative gap among provinces showed a trend that became wider.Areas with low efficiency were still showing a significant difference from areas with high efficiency.Gap between provinces was kind of revealing a pattern of Matthew effect.Basic public service supply efficiency was showing an uneven characteristic on spatial pattern.Global trend of supply efficiency was showing a falling trend from east to west,as for north south direction,the pattern was an inverted“U”type.Global autocorrelation analysis showed that the interprovincial basic public service supply efficiency had a positive spatial correlation,a mode of scattered-agglomeration-scattered-agglomeration can be observed as time advances.High-high agglomeration area mainly located in the Yangtze River Delta,the Pearl River Delta and other eastern regions.Low low agglomeration area is the west and northeast China.High-low and low-high agglomeration were mainly focused on the transition area.
