摘要:在我国经济已迈入高质量发展阶段,城市群作为区域经济发展的主要承载形式,如何提高区域一体化水平,促进城市群经济高质量发展,已成为当前区域经济研究的热点。本文将长三角城市经济协调会这一区域合作机制视为准自然实验,通过双重差分法建立实证模型考察区域一体化对长三角城市群经济高质量发展的影响,并对其异质性和作用机制进行深入探讨。研究表明:区域一体化提高了长三角城市群经济发展的整体质量,稳健性检验同样支持这一结论。异质性检验表明,区域一体化促进了长三角原位城市和新进城市的经济发展质量,且这种促进效应在原位城市要大于新进城市。机制检验表明,区域一体化可以通过市场整合机制、产业结构升级机制促进整体城市、原位城市和新进城市经济高质量发展,但经济联系机制的作用则存在区域差异性。

Abstract:In China, the economy has entered the stage of high-quality development. As the main bearing form of regional economic development, how to improve the level of regional integration and promote the high-quality development of urban agglomeration economy has become a hot spot of regional economic research. In this paper, the Yangtze River Delta City Economic Coordination Committee as a mechanism of regional cooperation is regarded as a quasi natural experiment. Through the double difference method, an empirical model is established to investigate the impact of regional integration on the high-quality economic development of the Yangtze River Delta city cluster, and its heterogeneity and mechanism are discussed in depth. The research shows that regional integration improves the overall quality of economic development of the Yangtze River Delta urban agglomeration, and the robustness test also supports this conclusion. The heterogeneity test shows that regional integration promotes the quality of economic development of the original cities and new cities in the Yangtze River Delta, and the promotion effect is greater in the original cities than in the new cities. The mechanism test shows that regional integration can promote the high-quality economic development of the whole city, the original city and the new city through the market integration mechanism and the industrial structure upgrading mechanism, but the role of the economic linkage mechanism has regional differences.
