| At present,the world has ushered in the fourth wave of industrial transfer.Premier Li Keqiang pointed out that there are two main transfer directions of China’s industry: the first is to transfer abroad and the second is to transfer to the central and western regions of China.Gansu Province is a province with rich resources and strong industrial foundation in the central and western regions.At present,the manufacturing industry in Gansu Province has obvious agglomeration characteristics,and there is a strong correlation between industrial agglomeration and ecological environment.Therefore,the research on the impact of industrial agglomeration and industrial ecological level in Gansu Province is of great value for Gansu Province to change the economic growth mode,seek a new development outlet and grasp new development opportunities.On the basis of combing and analyzing the existing relevant research results,taking the data from 2005 to 2019 as an example,this paper analyzes the impact relationship between industrial agglomeration and industrial ecological level in Gansu Province.Firstly,the location quotient index is used to calculate the agglomeration level of a single industry of manufacturing and producer services in 10 prefecture level cities of Gansu Province,and the relative difference of industrial agglomeration level is used to calculate the collaborative agglomeration level of manufacturing and producer services.Secondly,the input-output index system is constructed,and the super efficiency SBM model including unexpected output is used to calculate the industrial ecological level of 10 prefecture level cities in Gansu Province.Finally,on the basis of theoretical analysis,combined with the measured data,this paper constructs a regression model to make an empirical analysis on the impact of industrial agglomeration on the level of industrial ecology in Gansu Province.Through the research,this paper draws the following conclusions: the overall manufacturing agglomeration in Gansu Province shows a change trend of "decline first and then rise",the overall level of manufacturing agglomeration is not high,and the level of manufacturing agglomeration in various regions shows the characteristics of differentiation.Manufacturing industry agglomeration in Gansu Province has a significant reverse impact on the level of industrial ecology;The overall agglomeration level of producer services in Gansu Province is characterized by a wave of "decline rise decline",and there is no significant change in the agglomeration level of producer services in all cities of Gansu Province.The agglomeration of producer services in Gansu Province has a significant positive impact on the level of industrial ecology;On the whole,the collaborative agglomeration level of manufacturing and producer services in Gansu Province is high,showing the characteristics of "inverted U" change.The collaborative agglomeration of manufacturing and producer services in Gansu Province has a significant positive impact on the level of industrial ecology.According to the conclusion,some suggestions are put forward for reference: Gansu Province pays attention to the principle of moderation and quality when introducing manufacturing industry;Efforts should be made to improve the agglomeration level of producer services and the collaborative agglomeration level of manufacturing and producer services;To realize the deep integration,interaction and agglomeration of advanced manufacturing industry and producer service industry to lead the development;We should make joint efforts by various means to improve the ecological level of industry;Give play to the leading role of central cities. |
