Study On Green Economic Effect Of Synergistic Agglomeration Of Producer Services And Manufacturing Industry

Under the condition of high quality growth of socialist market economy,how to establish a virtuous circle of green industry system and achieve green sustainable growth has become the focus of China’s economic work today.In recent years,China’s producer services and manufacturing industries gradually show distinct regional agglomeration under the common influence of natural resource endowment and local government oriented policies.At the same time,with the unbalanced development of China’s economy and society,the agglomeration of producer services and manufacturing industries presents distinct differentiation characteristics.At present,China’s economy is transforming from an industrial economy to a service economy.Producer services and manufacturing industries go hand in hand,and their agglomeration characteristics become more and more obvious.From the practical experience of economic development,the "dual-wheel drive" of producer service industry and manufacturing industry has become a typical path for national industrial upgrading,optimization and upgrading.The synergistic aggregation of producer service industry and manufacturing industry has not only generated new economic growth points,but also brought new impetus to regional industrial development and economic and social development.It is also an important entry point to promote regional economic development and create a green economic growth mode.In this context,governments at all levels have begun to increase their efforts to support the coordinated development of the two industries and create a benign mode of coordinated development.Therefore,it is necessary to study the synergistic agglomeration of the two industries and its green economy effect based on the actual situation.Based on the theory of industrial collaborative agglomeration,new economic geography,core-edge theory and green growth theory,this paper reviews the theoretical mechanism of producer services and manufacturing producing green economy effect.In the empirical analysis,the ESDA method is firstly used to carry out a visual analysis on the agglomeration characteristics of producer services and manufacturing industries during 2005-2020,and then the panel data of prefecture-level cities,urban agglomerations and economic zones during 2005-2020 are utilized to calculate the industrial synergy index and super efficiency SBM index.The pattern of industrial collaborative agglomeration and efficiency characteristics of green economy at three scales of prefecture-level city,urban agglomeration and economic zone are analyzed.Finally,using the spatial Dubin model,based on the perspective of regional heterogeneity,the paper empirically analyzes the spatial effects of different scale industrial synergy agglomeration on the efficiency of green economy.The study reached the following conclusions:(1)From the perspective of the spatial pattern of producer services and manufacturing,the spatial distribution of producer services is more discrete than that of manufacturing,but the spatial distribution of the two also shows obvious commonality.The level of industrial collaborative agglomeration on the three scales presents a gradient distribution pattern from southeast to northwest.It also shows that the level of producer services and manufacturing synergistic agglomeration in China is unbalanced in three dimensions.Through the fitting study of economic development level,city size and industrial synergistic agglomeration index,it is found that the three are closely related,and the improvement of the synergistic agglomeration level on the three scales of prefecture-level city,urban agglomeration and comprehensive economic zone is in line with the driving route of "prefecture-level city-urban agglomeration-economic zone",and in line with the objective development trend of "point with surface".(2)From the perspective of green economy efficiency,the overall green economy efficiency of the country needs to be improved,and there is still a need for coordinated development between pure economic output and environmental pollution emission.There is still a large room for improvement of green economy efficiency,mainly because pure economic output and pollution output are not coordinated.All scales show an obvious overall layout of "high in the east and low in the west",which is consistent with the overall pattern of industrial collaborative agglomeration.The urban agglomerations with high collaborative agglomeration index and low variation coefficient have obvious similarity with the urban agglomerations with high green economy efficiency value.From the perspective of eight economic zones,the green economic efficiency value of Straits Economic Zone,Pan-Pearl River Delta Economic Zone and Pan-Yangtze River Delta Economic Zone from 2005 to 2020 is always greater than 1.The main factor affecting the total factor productivity is the low technological progress index,which indicates that it is necessary to strengthen the driving effect of technology on the economy.We still need to improve the technological level to promote the growth of local green economy.The efficiency level of green economy conforms to the objective development trend of "point to surface" in the three scales,but the spatial distribution is unbalanced.The influence mechanism of industrial collaborative agglomeration on the efficiency of green economy still needs further exploration.(3)The effects of industrial synergistic agglomeration on green economic efficiency at different scales are significantly different,reflecting different "local-proximity" effects.The synergistic agglomeration level of the two industries at the three scales of prefecture-level city,urban agglomeration and economic zone has a positive and significant local effect.After adding the adjacency matrix,the synergistic agglomeration of industries at the prefecture-level city has a significant effect on improving the green economic efficiency of the adjacent prefecture-level city.It shows that supporting the synergistic agglomeration of producer services and manufacturing at the prefecture level can promote the green economy efficiency of local and adjacent prefecture-level cities.The synergistic industrial agglomeration of prefecture-level cities within urban agglomerations can better promote the efficiency of green economy than that of prefecture-level cities outside urban agglomerations,indicating that thanks to the construction of urban agglomerations,the industrial synergy between cities and cities will also be enhanced.Therefore,attention should be paid to the internal construction of urban agglomerations and the coordination among prefecture-level cities.The collaborative promotion route of "prefecture-level city-between prefecture-level cities-urban agglomerations-economic zones" is formed,and then the reverse promotion is carried out through the route of "economic zones,urban agglomerations-between prefecture-level cities,and prefecture-level cities",so as to form the two-way promotion effect between the pairwise and pairwise industrial collaborative agglomeration in various scales.Therefore,based on the empirical research,this paper puts forward the following suggestions: optimize the spatial layout of industry,change the mode of economic development,give full play to the functions of government,stimulate the vitality of scientific and technological innovation,grasp the focus of development and clear the direction of development.
