| 摘 要： | 节能服务企业效率对于推动节能服务产业发展和确保国家“双碳”目标实现具有重要意义。运用三阶段SBM模型,对2020年60家中国节能服务上市企业的综合效率进行实证研究,并分析效率的影响因素。研究结果表明,经济发展水平对综合效率具有双重影响,合适的产业结构和较高的投入资本回报率有利于综合效率提升,而政府补贴与企业存续时间制约了综合效率改进;剔除环境因素与随机误差影响后,多数企业综合效率下降,整体效率偏低;提高规模效率是提升综合效率的关键,且绝大部分企业处于规模收益递增状态。研究最后提出创新补贴方式、建立企业认证制度、开展综合能源服务和推动企业间兼并重组等可行建议,以提升节能服务企业的综合效率。

| Abstract: | The efficiency of energy services companies is of great significance to promoting the development of the energy services industry and ensuring the realization of the national “carbon peaking and carbon neutrality goals”. Using a three-stage SBM model, an empirical study is conducted to examine the technical efficiency of 60 Chinese energy services listed companies in 2020, and analyze the factors affecting the technical efficiency. The results show that the level of economic development has a dual impact on technical efficiency; suitable industrial structure and high return on invested capital contribute to the improvement of technical efficiency, while government subsidies and company survival time restrict the improvement of technical efficiency. After eliminating the influence of environmental factors and random errors, the technical efficiency of most companies decreases, and the overall technical efficiency is low. The scale efficiency is the key to improving technical efficiency, and most companies are in the state of increasing returns to scale. Finally, the research proposes several feasible suggestions for further improving the technical efficiency of energy services companies, including innovating the way of subsidy, establishing a company certification system, carrying out comprehensive energy services, and promoting mergers and acquisitions among energy services companies. |
