扩容兼区划调整过程中城市群经济韧性引力演化及影响因素研究--以长三角城市群为例

Research on the gravitational evolution and influencing factors of economic resilience in urban agglomeration during the process of expansion and zoning adjustment:a case study of the Yangtze River Delta urban agglomeration

为了分析城市群在扩容兼区划调整过程中经济韧性的格局演化及影响因素,以长三角城市群为研究对象,利用熵权法、引力模型和空间面部杜宾模型对其进行分析。结果表明:扩容过程实现了城市群经济韧性的整体提升,扩容中经历的巢湖区划调整有利于促进合肥都市圈的发展;长三角城市群经济韧性引力整体实现迅速地升级,超强引力范围不断扩大,高强度引力大部分分布在长三角城市群东部地区;长三角城市群经济韧性存在显著的正向溢出效应,医疗条件近期对城市群经济韧性的影响强度更大,而就业保障和物流规模目前则是阻碍了长三角城市群经济韧性的提升。

To analyze the pattern evolution and influencing factors of economic resilience in the process of urban agglomeration expansion and zoning adjustment,the Yangtze River Delta urban agglomeration(YRDUA)is selected as the research object.The entropy weight method,gravity model,and spatial facial Durbin model are used to analyze it.The results show that the expansion process has achieved an overall improvement in the economic resilience of the urban agglomeration.The zoning adjustment of the ChaoHu city is conducive to promoting the development of the Hefei metropolitan.The overall economic resilience gravity of the YRDUA has been rapidly upgraded,and the scope of supergravity has continued to expand.However,most of the high-intensity gravity is distributed in the eastern region of the YRDUA.Moreover,there is a significant positive spillover effect on the economic resilience of the YRDUA.The recent impact of medical conditions on the economic resilience of the urban agglomeration is greater,while employment security and logistics scale have hindered the improvement of the economic resilience of the YRDUA.
