【摘要】：随着社会的发展,人类对于能源的需求量越来越大。然而,化石能源资源的枯竭以及其开采、使用对环境污染的压力增大,使人们不得不寻找和开发新的绿色能源,太阳能是可供选择的绿色能源之一。太阳能是各国政府新能源版图上不可或缺的一部分,基于太阳能光伏产业的发展前景及其在能源领域重要的战略地位,我国也相继出台了一系列的政策法规推动和促进光伏产业的发展。本文首先介绍了光伏产业研究的背景、意义及研究方法,阐述了相关理论基础及国内外对于光伏产业相关问题的研究综述;其次从光伏产业发展影响因素,产业生命周期,产业链和产业规模介绍我国光伏产业发展的现状;再次,采用DEA模型来研究我国光伏产业上市公司的技术效率问题。选取业内具有代表性的59家光伏上市企业,分别运用面板数据和截面数据测算了技术效率、纯技术效率和规模效率值,并对各类效率进行排名分析,然后运用Tobit回归模型进行影响因素分析,找出影响光伏企业效率的因素。研究得出:我国光伏上市公司投入产出效率整体不是太高,光伏产业综合效率与资产负债率相关性不显著,但综合效率和资产周转率、人均产值、直接成本率均呈显著正相关性。
[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.
