Research On Spatial Structure Evolution And Econometric Of Photovoltaic Power Generation Industry

Since the reform and opening up,with the progress of productivity and the improvement of people’s living standards,China has become a major energy consumer,forming a power supply system based on thermal power generation.The development of photovoltaic power generation conforms to the demand of supply-side reform,is the practice of green development concept,and is one of the important schemes to deal with air pollution and global climate change in China in recent years.In this paper,the photovoltaic power generation industry in 31 provinces,autonomous regions and municipalities directly under the Central Government except Hong Kong,Macao and Taiwan is taken as the main research object.The distribution status of photovoltaic power generation in each province from 2014 to 2018 is mainly studied,and the spatial distribution characteristics and influencing factors of photovoltaic power generation industry in China are explored.Firstly,the spatial distribution of China’s photovoltaic industry is described.Then,the spatial distribution characteristics of China’s photovoltaic industry are analyzed by standard deviation ellipse method.Finally,the spatial autocorrelation of China’s photovoltaic industry is tested,and a spatial econometric model is constructed to test the impact mechanism of its spatial correlation on the development of photovoltaic industry.It is found that the photovoltaic power industry in northern China is more developed,and the distribution ellipse shows the flat shape of northwest-east China trend,and gradually moves to southeast.The photovoltaic power generation of each province has significant spatial correlation from 2014 to 2018,and the cumulative growth of photovoltaic power generation in four years has significant spatial correlation.The most important factor affecting the growth of photovoltaic power generation is the increase of installed capacity of photovoltaic power generation equipment.The spatial correlation is mainly expressed as the perturbation correlation of residual term.There are other spatial factors which are not easy to observe that affect the growth of photovoltaic power generation.
