【摘要】：针对新能源产业上市公司经营效率问题,文章选取新能源产业的6个二级产业,14个三级行业的190家相关上市公司作为考察对象,在充分考虑风险因素的基础上,运用突变级数法和超效率数据包络法,对样本上市公司的经营效率水平进行实证研究,并通过相对效率判定法对新能源上市公司经营效率情况进行判定。研究发现:加入风险因素和未加入风险因素得到的新能源产业经营效率值差别很大,而且新能源产业上市公司的经营效率及其经营水平不均衡,均未达到最大规模产出,新能源上市公司的经营效率和规模收益有待于进一步提高。文章据此提出了提高经营效率和降低经营风险等产业发展建议。
[Abstract]:Aiming at the problem of operating efficiency of listed companies in new energy industry, this paper selects 6 secondary industries of new energy industry and 190 related listed companies of 14 tertiary industries as the object of investigation, on the basis of taking full account of risk factors. By using the catastrophe series method and the super-efficiency data envelopment method, this paper makes an empirical study on the operating efficiency level of the sample listed companies, and judges the operating efficiency of the new energy listed companies by the relative efficiency judgment method. It is found that the operating efficiency of new energy industry is very different from that of non-risk factors, and the operating efficiency and management level of listed companies in new energy industry are not balanced, all of them do not reach the maximum output. The operating efficiency and scale income of new energy listed companies need to be further improved. Based on this, the paper puts forward some suggestions for industrial development, such as improving management efficiency and reducing management risk.
