Abstract:The sustainable development of biomass power generation enterprises is crucial to improving the ecological environment, alleviating energy shortages and promoting a circular economy. This paper uses Bootstrap's modified DEA-Tobit model to conduct a comprehensive evaluation and analysis of the green technology innovation efficiency of 21 companies engaged in biomass power generation in 2018. The results show that: Bootstrap-adjusted DEA efficiency of biomass power generation enterprises is significantly lower than the initial DEA efficiency value; there is a large room for improvement in the efficiency of green technology innovation of biomass power generation enterprises, and there are significant differences among different enterprises; degree of specialization and industrial chain perfection, waste disposal amount and operating capacity are significantly positively related to the efficiency of green technology innovation of enterprises; while internal distribution mechanisms are significantly negatively related to the efficiency of green technology innovation of enterprises.
