摘　　要：绿色创新效率是影响企业长期可持续发展的重要因素。本文通过构建超越对数生产函数的随机前沿模型,对中国企业2011~2022年的绿色创新效率进行了测算分析,并通过对全要素生产率(TFP)进行三重分解,探讨了绿色创新效率及其影响因素。研究表明:(1)环境关注和劳动投入是企业绿色创新效率提升的主要贡献者;(2)从全要素生产率(TFP)分解结构看,绿色创新效率提升主要来源于技术效率改进(TEC)和技术进步(TC),而规模效率(SC)的持续恶化却弱化了两者的作用;(3)异质性实证检验表明,西部地区的绿色创新效率最高,其次是东部,中部地区的绿色创新效率最弱,分行业检验结果则表明重污染行业效率高于非重污染行业,高科技行业高于非高科技行业。本文根据研究结论,提出相关政策建议。Green innovation efficiency is an important factor affecting the long-term sustainable development of enterprises.By constructing a stochastic frontier model based on the transcendental logarithmic production function,this paper calculates the green innovation efficiency of Chinese enterprises from 2011 to 2022,and discusses the efficiency and source of green innovation growth by triple-decomposition of TFP.The results show that:(1)environmental concern and labor input are the main contribu⁃tors to the improvement of green innovation efficiency of enterprises.(2)From the perspective of TFP decomposition structure,the improvement of green innovation efficiency mainly comes from the improvement of technological efficiency(TEC),followed by technological progress(TC),while the continuous deterioration of scale efficiency(SC)weakens the role of the two.(3)Hetero⁃geneity analysis shows that the green innovation efficiency in the western region is the highest,followed by the eastern region,and the green innovation efficiency in the central region is the weakest.
