我國光伏產(chǎn)業(yè)技術(shù)效率的實(shí)證分析
[Abstract]:With the development of society, the demand for energy is increasing. However, the depletion of fossil energy resources and the increasing pressure of its exploitation and use on environmental pollution make people have to find and develop new green energy. Solar energy is one of the alternative green energy sources. Solar energy is an indispensable part of the new energy layout of governments. Based on the development prospects of the solar photovoltaic industry and its important strategic position in the energy field, China has also issued a series of policies and regulations to promote and promote the development of photovoltaic industry. In this paper, the background, significance and research methods of photovoltaic industry are introduced firstly, and the related theoretical basis and domestic and international research on photovoltaic industry are summarized. Secondly from the photovoltaic industry development factors industrial life cycle industry chain and industry scale introduced the current situation of PV industry development in China. Thirdly the DEA model is used to study the technical efficiency of listed companies in China PV industry. Select 59 representative photovoltaic listed enterprises in the industry, use panel data and cross-section data to calculate the technical efficiency, pure technical efficiency and scale efficiency, and rank and analyze all kinds of efficiency, and then use the panel data and cross-section data to calculate the technical efficiency, pure technical efficiency and scale efficiency. Then the Tobit regression model is used to analyze the influencing factors to find out the factors that affect the efficiency of photovoltaic enterprises. It is concluded that the overall input-output efficiency of PV listed companies in China is not too high, and there is no significant correlation between the overall efficiency of PV industry and asset-liability ratio, but the overall efficiency, asset turnover ratio and per capita output value are not significantly related to the overall efficiency of PV industry. The direct cost rate showed significant positive correlation.
