基于DEA模型的风电企业融资效率影响因素分析

Analyses on the Influencing Factors of Financing Efficiency of Wind Power Enterprises Based on DEA Model

基于“双碳”背景,利用我国31家风电企业的财务数据,借助DEA-Malmquist模型研究了2015—2022年风电行业静态与动态融资效率,发现近半数企业仍处于低效率区间;使用Tobit模型对各融资效率影响因素进行回归分析,发现资产周转率、净资产收益率等有正向显著影响作用,资产负债率等有负向影响作用。企业在日常生产经营过程中应关注政策导向,注意自身资产结构并加大科研投入以提高融资效率。

Based on the background of"double carbon",Using the financial data of 31 wind power enterprises,this paper studied the static and dynamic financing efficiency of wind power industry from 2015 to 2022 with the DEA-Malmquist model,and found that nearly half of the enterprises are still in the low efficiency range.Tobit model was used to conduct regression analysis on the influencing factors of financing efficiency,and it was found that asset turnover ratio and return on equity have a positive and significant effect,while asset-liability ratio has a negative effect.Therefore,in the process of daily production and operation,enterprises should focus on policy orientation,pay attention to their own asset structure and increase scientific research investment to improve financing efficiency.
