| The Yangtze River Delta region is the region with the highest level of regional integration in China,and the current international and domestic situation has highlighted the importance of the integration of the Yangtze River Delta.The regional integration of the Yangtze River Delta includes many aspects such as industry,transportation,and market,among which the development of industrial integration is an important foundation.Exploring the high-quality development level,influencing factors,and action paths of industrial integration in the Yangtze River Delta can provide theoretical and decision-making basis for the formulation of high-quality development planning and policies for regional integration in the Yangtze River Delta.Firstly,the theoretical basis,relevant literature and development status of industrial integration and high-quality development are sorted and reviewed.Secondly,this thesis focuses on the agreed division of labor theory and the five concepts of high-quality development,and constructs the index system of high-quality development of industrial integration in Yangtze River Delta region,which includes five dimensions: foundation of high-quality development of industrial integration,dynamics of high-quality development of industrial integration,performance of highquality development of industrial integration,green development of industrial integration and social welfare of high-quality development of industrial integration,and uses the panel entropy weight method to measure the comprehensive index of highquality development of industrial integration in Yangtze River Delta region.The spatial exploratory analysis method and Markovian method are used to reveal the spatial distribution characteristics and spatial-temporal dynamic evolution trend of the highquality development of industrial integration in the Yangtze River Delta region.The results show that the level of high-quality development of industrial integration in the Yangtze River Delta region is gradually increasing;the spatial distribution of the level of high-quality development of industrial integration is higher in the east than in the west,and the central cities are higher than the neighboring cities;the spatial dependence of the high-quality development of industrial integration in each region;the clustering pattern of high-quality development of industrial integration in the Yangtze River Delta region is relatively stable,and there is a positive spillover effect.Thirdly,construct a spatial panel model to analyze the spatio-temporal correlation of influencing factors on the high-quality development of industrial integration in the Yangtze River Delta.It is found that there is a significant spatial autocorrelation in the high-quality development of industrial integration in the Yangtze River Delta.Innovation driven,opening up,government regulation and transportation,as well as industrial structure,have a positive promoting effect on the high-quality development of local industrial integration.At the same time,the improvement of innovation driven,opening up,government regulation and transportation has a strengthening effect on the surrounding areas.Then,a spatiotemporal geographic weighted regression model(GTWR)was constructed to analyze the spatiotemporal heterogeneity effects of influencing factors.The estimation results of the GTWR model show that: on the whole,innovation drive,openness,government regulation,socio-economic development,transportation,factor endowment,market mechanism and industrial structure have positive effects on the high-quality development of industrial integration,while environmental regulation has negative effects on the high-quality development of industrial integration.From the local perspective,there are differences in the degree of influence of each factor on the high-quality development of industrial integration;from the time dimension,the trend of environmental regulation on the high-quality development of industrial integration is decreasing and then increasing,the change of transportation is not obvious,and the rest of the influencing factors increase with time;from the spatial dimension,innovation drive,openness to the outside world and environmental regulation have more influence on the eastern Yangtze River Delta From the spatial dimension,innovation drive,opening up and environmental regulation have greater influence on the eastern Yangtze River Delta region,government regulation,socio-economic development level,factor endowment and industrial structure have greater influence on the central and subcentral cities,and transportation has greater influence on the coastal region.Finally,suggestions were put forward on how to enhance the high-quality development of industrial integration,such as accelerating regional linkage,enhancing the driving force of central city radiation belts,increasing innovation efforts,and improving infrastructure construction,in order to promote the high-quality development of industrial integration. |
