Research On Analysis And Evaluation Of Value-added Capability Of Wind Power Listed Companies

The increasingly depleted fossil energy and deteriorating ecological environment have accelerated the global energy transformation.Renewable energy has developed rapidly on a global scale,and the level of development and utilization of wind energy has gradually increased.Driven by national policy support and technological progress,China’s wind power industry has experienced a period of rapid development.The newly installed wind power installed capacity and cumulative installed capacity have increased substantially,and ranked first in the world in seven years.However,there are some disadvantages behind the rapid development of wind power industry.Although China’s wind power generation is considerable,the utilization rate has not reached the relevant standards.For wind power listed companies,"abandon wind and limit electricity”reduces the company’s efficiency and hinders the value added of the company.Energy storage,as an effective means of improving the utilization rate of wind power,plays an important role in the process of realizing value-added of the company.Therefore,it is of great theoretical and practical significance to study the value-added ability of wind power listed companies on the basis of considering energy storage.The main research content of this paper is to analyze and evaluate the value-added ability of wind power listed companies.Firstly,according to the wind power value chain,China’s wind power listed companies are defined,and their development status is analyzed from the macro and micro levels.Secondly,the influencing factors affecting the value-added ability of listed companies in wind power are analyzed,and the main influencing factors are extracted and analyzed by principal component analysis.Thirdly,based on the results of principal component analysis,the evaluation index system of value-added capability of listed companies in wind power is constructed.The data envelopment analysis method is used to statically evaluate the value-added ability of listed wind power companies that include energy storage and listed wind power companies that do not from four perspectives of technical efficiency,pure technical efficiency,scale efficiency and efficiency projection.Finally,the Malmquist index was introduced to evaluate the dynamics of the two types of wind power listed companies that accounted for energy storage.Based on the evaluation results,the cluster analysis of wind power listed companies was carried out,and targeted recommendations were put forward.The empirical research results show that the value-added ability of wind power listed companies considering energy storage in China is better than that of wind power listed companies that do not consider energy storage.Wind power listed companies can enhance the company’s sustainable development by introducing energy storage and enhancing value-added capabilities.Value-added is a key issue for the sustainable development of listed wind power companies.This paper compares and analyzes the value-added capabilities of listed wind power companies that take energy storage into account and listed wind power companies that do not take energy storage into account from multiple perspectives,providing useful ideas for wind power listed companies to realize value added.
