摘要 运用产出导向的两系统模型对我国传统能源和新能源上市公司的生产经营效率以及效率改进方向进行比较研究。研究结果表明传统能源行业的平均效率显著高于新能源行业的平均效率;国有企业和民营企业的所有制身份差异在同一类能源行业内没有明显的效率差距,但在传统能源和新能源行业间的所有制身份效率差异显著;传统能源和新能源行业均面临成本控制压力,传统能源企业在营业成本、员工总数和本科学历以上人数占比方面冗余严重,新能源企业的成本控制空间重在固定资产和研发支出上,同时营业收入和净利润的不足表明新能源企业面临更大的规模扩张与利润增长压力。

Abstract: This paper uses output-oriented two system model to compare traditional energy and new energy listed companies’ production and operation efficiency as well as their efficiency improvement. The results show that the average efficiency of traditional energy industry is significantly higher than that of new energy industry. The ownership difference between state-owned enterprises and private enterprises does not result in obvious efficiency gap in the same energy sector, but in traditional and new energy sectors, ownership makes a great difference. Traditional energy and new energy industries are both facing huge pressure of cost control: in particular, in traditional energy companies, operating cost, total number of employees and the percentage of bachelor degree or above are redundant seriously, new energy enterprises undertake more pressure in aspects of fixed assets and R&D investment. At the same time, the shortage of operating income and net profit shows that the new energy enterprises face greater pressure in scale expansion and profit growth.
