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。As for the operational efficiency of new energy listed companies, this paper selects six secondary industry of new energy industry, 14 tertiary industry 190 listed companies as study samples. By taking risk factors into account, catastrophe progression method and DEA super efficiency model are used to study the samples. The paper conducts the empirical study on the listed company＇s operational efficiency, through the relative efficiency of judging method to determine new energy management efficiency of the listed companies. It is found that operation efficiency is obtained by adding the risk factors or not varies considerably, moreover, the new energy industry listed company＇s operational efficiency and management level is not balanced and operational efficiency and scale benefits of new energy listed companies needs to be improved. Accordingly, the paper puts forward some industrial development proposals for improving operational efficiency and reducing operational risks.
