Spatiotemporal evolution of photovoltaic equipment manufacturing industry in China and its influencing factors
China is currently undergoing a profound paradigm shift towards sustainable economic development,marked by an ardent pursuit of high-quality economic growth and the establishment of a low-carbon,high-efficiency energy system in response to the"dual carbon"goals.Within this overarching context,as a strategic emerging industry,the photovoltaic equipment manufacturing industry has ascended as a linchpin in the industrial transformation towards green economy and it is also a core industry in the global competition for development.A better understanding of the industry's spatiotemporal dynamics and its influencing factors holds particular significance for both theoretical discourse and practical applications.Based on enterprise data and urban socio-economic data,this article depicts the spatial layout and evolution characteristics of China's photovoltaic equipment manufacturing industry from 2000 to 2021.By using a random effect panel Tobit model,it endeavors to unravel the main factors and formation mechanism of the location choice of China's photovoltaic equipment manufacturing enterprises.The main results are as follows.(1)The photovoltaic equipment manufacturers in China are mainly distributed in economically robust regions such as Jiangsu,Shandong,Hebei,and Guangdong,with a discernible trend of spatial diffusion from the eastern coastal areas towards the central and western regions of China.(2)The spatial diffusion patterns of China's photovoltaic equipment manufacturing industry can be divided into three categories:adjacent diffusion,hierarchical diffusion and channel diffusion.(3)During the study period,local industrial foundation,total carbon emissions,the level of scientific and technological innovation,the amount of policy subsidies,and the spatial proximity of core enterprises are the main factors driving the evolution of the spatial layout of China's photovoltaic equipment manufacturing industry,but there is a significant spatiotemporal difference in the mechanism of each factor.(4)Three types of layout models have been observed in China's photovoltaic equipment manufacturing industry:market-cost-oriented type,policy-resource-oriented type,and comprehensive type.With the changing competitive environment in both domestic and international markets,the diversified layout model aimed at enhancing the safety and overall resilience of industrial and supply chains is becoming increasingly prominent.Our research results are expected to provide theoretical basis and decision-making references for spatial development and layout optimization for China's photovoltaic equipment manufacturing industry.
