Analysis of Ecological Energy Development Efficiency Base on the DEA Model-Take China’s Wind Power Industry as an Example

Wind power has played a huge role in replacing conventional fossil energy and reduces greenhouse gas emissions. So support the development of wind power industry is the main part to push the earth ecological protection. In this paper, we select 30 representative public companies in the wind power industry as samples and extract their financial data as panel analysis. Then we analyse the financial support efficiency for Chinese wind power industry Based on data envelopment analysis (DEA). According to the empirical results, a show that Chinese wind power industry ignores the research and development of science and technology and is sensitive to the macro environment. These are just the points where we need to improve.
