Analysis Of The Spatial Pattern Of Urban New Energy Vehicle Industry Innovation And Its Influencing Factors

Under the background of "carbon peak and carbon neutrality","vehicle energy integration" puts forward new requirements for innovation-driven development,and the new energy vehicle industry will inevitably become an important growth pole for urban innovation and development.Taking Guangzhou as an example,this paper first studies the influence mechanism of urban new energy vehicle industry innovation spatial pattern,analyzes the elements of urban innovation system,analyzes the elements of urban industrial innovation space from four main dimensions:innovation foundation,innovation service,innovation subject and innovation environment,and explores its agglomeration and diffusion mode from the perspective of agglomeration economy and agglomeration non-economy.Secondly,the differences in the spatial pattern of innovation and its distribution characteristics in the new energy vehicle industry in Guangzhou are summarized and studied,and the spatial autocorrelation analysis,kernel density analysis and grid analysis are used to measure the non-equilibrium of the innovation space.Finally,the empirical model is used to test the influencing factors of the spatial pattern of innovation of Guangzhou new energy automobile industry under the above theoretical framework,and provide policy suggestions for the spatial planning and layout of urban industrial innovation.The results show that first,the new energy automobile industry in Guangzhou has the characteristics of a significant increase in the number of patents year by year and an uneven distribution of innovation space,and the main body of innovation space is Huangpu,Tianhe,Yuexiu,Haizhu and Liwan districts,showing an innovation space pattern of dual evolution of agglomeration and diffusion,which is manifested as from low-level agglomeration to optimized and balanced development.Second,among the main body of innovation space in Guangzhou’s new energy vehicle industry,the active role of innovation foundation and innovation subject is particularly prominent,which shows the importance of urban innovation atmosphere and talents in innovation and development.The innovation environment and innovative services have not played a significant role,probably because Guangzhou’s infrastructure and innovative service industry are not well developed.There are differences in the degree of influence and effect of the innovation influencing factors of these four dimensions on each district and county,and the specific reasons need to be further studied.Among the driving factors of the main body of Guangzhou new energy vehicle innovation space,the core driving factors are the existing innovation level,the number of enterprises in the information transmission,software and information technology service industry,and the number of personnel in the education industry and scientific research and technical service industry.Therefore,it is necessary to promote the enhancement of urban industrial innovation capabilities and improve the optimal layout of urban industries by strengthening the level of innovative services,implementing the talent strategic plan,strengthening the supporting and leading role of urban transportation,and promoting urban informatization construction.
