市场整合、对外开放与长三角区域高质量发展

Market Integration,Opening up and High-quality Development in the Yangtze River Delta Region

文章构建高质量发展水平评价指标体系,采用耦合协调度模型度量长三角41个地级及以上城市2005—2020年高质量发展水平,结合空间自相关性分析长三角区域高质量发展空间格局演变特征,并借助地理探测器识别市场整合、对外开放及二者交互作用对长三角区域高质量发展的影响。研究发现:①长三角区域高质量发展空间格局呈现出以直辖市和省会城市为关键节点的均质化发展态势,存在显著的空间相关性;②市场整合与对外开放对长三角区域高质量发展空间格局均有显著推动作用,其中,子要素对外贸易开放是长三角区域实现高质量发展的关键驱动力;③市场整合与对外开放的交互作用对长三角区域高质量发展呈现出非线性增强作用,对外贸易开放对其他要素的影响起到催化剂效应。

This study builds a comprehensive evaluation index system,adopts a coupled coordination degree model to measure the level of high-quality development of 41 cities at prefecture level and above in the Yangtze River Delta from 2005 to 2020,combines spatial autocorrelation to analyze the evolution characteristics of the spatial pattern of highquality development in the Yangtze River Delta,and identifies the impact of market integration,opening up and the two on the regional high-quality development with the help of geographic detectors.It's found that:1)The high-quality development in the Yangtze River Delta shows the even development spatial pattern,which takes municipalities and provincial capitals as key nodes,there are significant spatial correlations.2)Both market integration and opening up have a significant role in promoting the spatial pattern of high-quality development in the Yangtze River Delta,among which,the opening up of foreign trade is the key driver of high-quality development in the Yangtze River Delta.3)The interaction between market integration and opening up presents a non-linear enhancement to the high-quality development of the Yangtze River Delta,in which the opening up of foreign trade plays a catalytic effect on other factors.
