Research On The Efficiency And Influencing Factors Of Clean Energy Investment In China's Power Enterprises

At present,countries around the world are accelerating the transition to clean enerey,and clean energy investment will become an indispensable part of the energy economic revolution.The power industry is an important part oi the national economy and is facing major problems in energy structure adjustment and low-carbon development.In recent years,China's power companies have continuously increased the proportion of clean eneruy investment adjusted the power production structure,and continuously promoted the process of energy and power reform.In this context,the thesis studies the investment efficiency of clean energy in China'spower companies.The topic selection has important theoretical and practical significance.The paper studies the efficiency of clean energy investment and its influencing factors in China's power companies,and analyzes them according to the "status-efficiency-factors".Through the analysis of the research status at home and abroad and the investigation of power companies,the paper analyzes and evaluates the characteristics of clean energy investment in China's power companies.On the basis of theoretical analysis and current situation analysis,it focuses on the evaluation of the efficiency of clean energy investment in China's powercompanies,and conducts empirical research on the factors affecting the efficiency of clean energy investment.Through the determination of decision-making unit,design input and output goal,and designing the evaluation system of clean energy investment efficiency of power enterprises-the DEA evaluation model of clean energy investment efficiency was constructed,and China's power listed companies were selected for five consecutive years from 2013 to 2017.The panel data,the sample company's comprehensive efficiency value.pure technical efficiency value and scale efficiency value are measured and analyzed,and the horizontal difference analysis of the investment efficiency of each enterprise and the trend analysis of the five-year overall industiy investment efficiency chanee are studied.It shows that the investment in clean enenzy of China's power companies is increasine year by year,and the investment efficiency is showing a trend of decline in stability.It is not ideal,but with the mature mode of clean energy investment,the efficiency of clean eneray investment of China's power companies will be very high.Good improvement:the research also uses the multiple regression model to empirically study the factors affecting the efficiency of clean energy investment of listed companies in power companies.The reression results show that the investment efficiency of China's power companies' clean energy listed companies is affected by the company's net assets per share,assets and liabilities.Rate,the proportion of the largest shareholder Factors.On the basis of theoretical analysis and empirical research.the paper finally puts forward suggestions for improving the efficiency of clean energy investment in power companies in China.
