Research on Investment Efficiency Evaluation of New Energy Lithium Battery Enterprises in China
In recent years,the development and utilization of clean energy has aroused wide attention from all walks of life,and new energy lithium batteries have gradually been favored by countries with their green and environ-mental protection characteristics.This paper takes China's new energy lithium battery listed companies as the research object,analyzes their investment status,and uses DEA model and Malmquist index model to evaluate the overall in-vestment efficiency of enterprises from static and dynamic perspectives.The research results show that the investment scale of new energy lithium battery enterprises has increased year by year,but some enterprises have problems in cost control and innovation mechanism;The static investment efficiency of new energy lithium battery enterprises has not reached an effective level,and many new energy lithium battery enterprises have insufficient investment,resulting in low comprehensive technical efficiency;Due to the outstanding problem of investment scale and slow technological up-date,the dynamic investment efficiency of new energy lithium battery enterprises is also declining year by year.In view of the problems faced by new energy lithium battery enterprises,the relevant suggestions are put forward.
