Research On The Economic Growth Effect Of Synergistic Agglomeration Of Productive Services And Manufacturing Industries In The Yangtze River Economic Belt

Along with the slowdown in the development of traditional manufacturing industries,the rapid development of modern service industries,the strengthening of coordinated industrial development,and the establishment of a high-quality industrial development system are important contents for the sustainable and healthy development of the Yangtze River Economic Belt.In this process,promoting the growth of economic aggregate and the improvement of economic efficiency through industrial synergy are one of the key points of the coordinated industrial development.Only by understanding the effects of synergistic agglomeration economic growth and what factors will affect the growth effect,can we effectively promote the benign interaction between the productive service industry and the manufacturing industry,and make the industry develop towards the rationalization of the configuration and the advanced structure of the structure,so as to achieve regional High-quality economic development.This article first from the angles of industrial concentration and coordination agglomeration of producer services and manufacturing development research status at home and abroad combing and summary,and then use the Yangtze river economic belt of 11 provinces and cities in 2003-2017 data,various provinces and cities of the Yangtze river economic belt development industry as a whole,the development status of development of producer services and manufacturing descriptive analysis,and by calculating the location entropy index from the industry level of the Yangtze river economic belt provinces of producer services and manufacturing industryagglomeration status analysis and evaluation.On this basis,build collaborative cluster index,measure provinces of producer services and manufacturing agglomeration level together,11 provinces and cities of the Yangtze river economic belt industry coordinated development present situation analysis,and development process of regional cooperation,the level of urban agglomeration coordinated deficiencies,problems such as lack of rigidity and strong constraint mechanism.Finally,the fixed effect model is adopted to make an empirical analysis of the economic growth effect of collaborative agglomeration.The research results show that the current collaborative agglomeration of manufacturing industry and modern service industry has a significant positive effect on economic growth,but the effect on economic efficiency is not significant at present.The effect of collaborative agglomeration on economic growth is influenced by many factors.The improvement of the level of informationization,urbanization,opening up,and industrial structure has a positive impact on the growth of economic aggregates and economic efficiency,while the level of government intervention has a negative impact on economic growth.Based on the above research,the corresponding policy recommendations were proposed from the government,regional and industrial levels: first,to improve the quality of industrial agglomeration and accelerate the development of coordinated agglomeration;second,to accelerate the transformation of government functions and promote the integration of industry and city;Find the right industry positioning and accelerate the development of regional advantageous industries;the fourth is to optimize the spatial layout and form an efficient regional division of labor and cooperation network;the fifth is to increase human capital investment and improve the level of information;the sixth is to improve the level of external development and improve infrastructure.
