Study On The Effect Of Industrial Synergy Agglomeration On Economic Growth In Three Urban Agglomerations

Nowadays,the world has rapidly entered the information age,but the economic growth has shown obvious imbalance in space,and this difference is also reflected in the industrial development.Since the 18 th National Congress of the Communist Party of China(CPC),the strategy of regional coordinated development has been put forward with great foresight.With the implementation of supply-side structural reform policy,high-quality industrial development has become a hot topic of scholars’ research.As an effective way to promote the high-quality development of regional economy,the spatial agglomeration situation and internal structure of industries all affect the economic growth.This paper mainly proposes a complete set of methods to measure CO of industrial collaborative agglomeration index,and studies the change trend of CO of industrial collaborative agglomeration index and the analysis of its influence mechanism on economic growth.Therefore,this paper first analyzes the current situation of the economic development of the three urban agglomerations,and then calculates the current situation of the industrial collaborative agglomeration in the three urban agglomerations from 2010 to 2019 by using the method of location entropy and industrial collaborative agglomeration index.Secondly,the development of coordinated industrial agglomeration in city agglomerations is deeply analyzed from three perspectives of time series difference,spatial correlation and regional convergence by using coefficient of variation,Moran scatter plot and synergy effect index.The panel data model calculates the internal relationship of industrial synergy agglomeration.On the basis of constructing the influencing factors model of industrial synergy agglomeration on economic growth,the threshold effect model is used to analyze the viewpoints and prospects of this paper.It is found that the characteristics of industrial synergy agglomeration in urban agglomerations are different.Industrial development is in a complex dynamic system with spatial attributes,namely dependency and difference.The regional economic development of urban agglomerations fluctuates and improves without forming a stable economic development trend.The CO level difference of industrial collaborative agglomeration index between urban agglomerations gradually increases,but the difference within the region decreases.In terms of influencing factors on economic growth,city size,fixed asset investment and industrial synergy agglomeration level all have significant effects.The difference of industrial synergy agglomeration level is an important reason that leads to the difference of regional economic development level.
