摘要
在中国“双碳”目标与经济社会发展方式绿色转型的背景下,绿色创新成为发电企业实现效益增长和环境友好的重要支撑。然而,当前发电企业的绿色创新评价体系尚未确立,绿色创新效率处于何种水平尚未可知。因此,本文首先构建了发电企业的绿色创新效率评价指标体系,并运用两段加性网络DEA模型测算了2020—2022年我国发电企业的绿色创新效率;最后采用模糊集定性比较分析(fsQCA),为其设计了两阶段绿色创新效率的综合改善路径。结果表明:(1)发电企业绿色创新整体效率均值仅为0.498,整体效率偏低。(2)绿色创新研发阶段效率略优于成果转化阶段效率,两阶段发展不协调。(3)绿色创新研发阶段可通过内外部协同驱动(H1、H2)实现效率提升,绿色创新成果转化阶段效率存在企业内驱型(H3)和政府主导型(H4)两种提升路径。
In the context of carbon peaking and carbon neutrality goals and green transformation,green innovation has become an important support for power generation enterprises to achieve efficiency growth and environmental friendliness.In this paper,the evaluation index system of green innovation efficiency of power generation enterprises is constructed,and the green innovation efficiency of power generation enterprises from 2020 to 2022 is measured by using a two-segment additive network DEA model.Finally,the fuzzy set qualitative comparative analysis(fsQCA)is used to design a comprehensive improvement path for the efficiency of green innovation in two stages.The results show that:(1)The average overall efficiency of green innovation of power generation enterprises is only 0.498,and the overall efficiency is low.(2)The efficiency of the green innovation R&D stage is slightly better than that of the achievement transformation stage,and the development of the two stages is not coordinated.(3)In the green innovation R&D stage,efficiency can be improved through internal and external collaborative drive(H1,H2),and there are two ways to improve the efficiency in the transformation stage of green innovation achievements,namely enterprise internal drive(H3)and government-led(H4).
