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 coordinating social welfare with economic growth is one of the core issues of urban sustainable development. Taking the 41 cities in the Yangtze River Delta as the research unit, the index of social welfare and economic growth was measured by entropy method, and the degree of coordination, degree of development and degree of coupling were calculated by means of the evaluation model of coupling coordination. Based on this, the types of coupling coordination and their spatial correlation Characteristics. The results show that: (1) The overall trend of social welfare and economic growth in 41 prefectures and cities in the Yangtze River Delta fluctuates upward. However, in recent years, due to the economic downturn, social welfare has been slowly declining with economic growth. 2 Social Welfare and Economic Growth Index have good spatial consistency and relatively stable pattern. Compared with social welfare, the first characteristic of economic growth is obvious, and the difference between cities is relatively prominent. 3 coupling degree has obvious rules of spatial heterogeneity, forming a “z-type coupling and coordinative development axis” of “Ning-Ning-Hu-Hang-Yong”. 4 Most cities in Anhui Province belong to the type of social welfare and the imbalance of economic growth. It is imperative to strike a balance between the two and seek ways to optimize the evolution of social welfare and economic growth towards a higher level of coupled and coordinated development.
