长三角地区社会福利与经济增长耦合协调时空分异

TEMPO-SPATIAL DIFFERENCE OF COUPLING AND COORDINATION OF SOCIAL WELFARE AND ECONOMIC GROWTH IN THE YANGTZE RIVER DELTA

社会福利与经济增长的耦合协调是城市可持续发展的核心问题之一。以长三角41地市为研究单元,运用熵值法测度社会福利与经济增长指数,进一步借助耦合协调评价模型计算协调度、发展度以及耦合度,并据此进行耦合协调类型划分及其空间关联特征分析。结果表明:1长三角41地市社会福利与经济增长整体趋势波动上升,但近年来受经济下行影响,社会福利随经济增长出现缓慢下降趋势。2社会福利与经济增长指数空间吻合度较高且格局相对稳定。相比社会福利,经济增长首位特征明显,市际差异相对突出。3耦合度具有明显空间分异规律,初步形成"合宁沪杭甬"Z字型耦合协调发展轴带。4安徽省多数地市属于社会福利与经济增长失调衰退类型,亟需平衡二者关系,寻求优化路径,推动社会福利与经济增长向更高层次耦合协调发展类型演进。

Coupling and coordination of social welfare and economic growth is one of the core issues of sustainable development. Using 41 cities in the Yangtze River Delta and applying entropy method and evaluation model, we calculated social welfare and economic growth index, and calculated coordination, development and coupling degree for classification types and spatial characteristics studies. The results showed that： 1） Social welfare and economic growth fluctuation showed an upward trend. Due to the economic downturn in recent years, social welfare has been declining slowly with the growth of economy. 2） Social welfare and economic growth index have high spatial consistency and relatively stable pattern. Compared to social welfare, the first primate feature of economic growth is obvious, and the inter-city difference is relatively prominent. 3） Coupling degree has obvious spatial differentiation rule, and initially formed the Z-type coupling and coordination development axis of Hefei-Nanjing-Shanghai-Hangzhou-Ningbo. 4） Most cities in Anhui Province belonged to the type of imbalance declining of social welfare and economic growth. Therefore, we suggest that it is time to balance the relationship, to seek optimizing path to promote social welfare and economic growth toward a higher level.
