基于生态位与两阶段DEA模型的我国新能源上市公司融资效率研究

Research on Financing Efficiency of New Energy Listed Companies in China Based on Niche and Two-Stage DEA Model

为完成新能源产业可持续发展的目标,引入生态位理念并构建两阶段DEA模型,以江苏省为分析对象,对该省新能源上市公司的筹资、配置以及融资效率进行实证研究。实证结果表明,我国新能源企业的融资效率普遍较低,具有很大的进步空间。因此,要重视筹资效率与配置效率的共同进步及改善企业融资生态位,构建良好的融资外部生态环境,提高企业融资效率。

In order to achieve the goal of sustainable development of new energy industry, the concept of niche was introduced, and a two-stage DEA model was constructed. Jiangsu province was chosen as the analysis object to conduct an empirical study on the financing, allocation and financing efficiency of new energy listed companies in the province. The empirical results show that the financing efficiency of new energy enterprises in our country is generally low and there is a lot of room for improvement. We should pay attention to the common progress of financing efficiency and allocation efficiency and improve the financing niche of enterprises, construct a good external ecological environment for financing and improve the financing efficiency of enterprises.
