长三角一体化影响区域经济联动的政策效应与机制研究
Research on the policy effects and mechanisms for the integration of the Yangtze River Delta on regional economic linkage
摘要
Abstract
In order to explore whether and how the regional integration policy in the Yangtze Riv-er Delta can affect the regional economic linkage,this paper takes the expansion of the"Yangtze River Delta Urban Economic Coordination Committee"as a quasi natural experiment.Based on the panel data from 41 cities in the Yangtze River Delta from 2006 to 2022,after analyzing the changes in the economic linkage pattern under the influence of the integration policy in the Yan-gtze River Delta,this paper uses a multi period double difference model to evaluate the impact of the integration of the Yangtze River Delta on the economic linkage.The results show that:the network presents the characteristics of small world structure;the relationship between network density and correlation shows an overall trend of fluctuating and rising.Regional economic ties are strengthened,but there is still room for improvement.Joining the Yangtze River Delta has significantly improved the level of urban economic linkage,and this conclusion has strong robust-ness.The integration of the Yangtze River Delta promotes regional economic linkage by enhan-cing market potential;the level of technology diffusion and transportation improvement exerts a positive moderating effect on the promotion of economic linkage by the integration of the Yangtze River Delta.Heterogeneity analysis finds that there are significant differences in the promotion of economic linkage by the integration of the Yangtze River Delta among cities of different sizes and provinces.关键词
