Research on Operational Efficiency of Photovoltaic Power Companies and the Influences:Analysis Based on DEA-Malmquist-Tobit Model
In pursuit of the carbon peaking and carbon neutrality goals,it is of paramount importance to evaluate operational efficiency of photovoltaic(PV)power companies and the influences on it based on scientific evidences,to promote the high-quality development of the companies and industry.Based on the panel data of listed PV power companies from 2014 to 2022,the DEA-Malmquist-Tobit model was used to measure the operating efficiency and the dynamic changes of in total factor productivity(TFP),and the main influencing factors of operating efficiency were empirically analyzed.The results show that in the target nine years,the fact that the TFP of the PV plants saw a slight 1.8%growth which is substantially attributed to rising technological progress.Meanwhile,the variables,such as shareholding structure,earnings per share,and other variables,have vital roles in operating efficiency of PV power companies.
