工业企业生态效率与科技创新耦合协调及影响因素研究

本文以2004—2017年我国29个省份工业企业为研究对象,通过构建生态效率与科技创新评价指标体系,运用耦合协调度模型和PVAR2模型,研究分析工业企业两者耦合协调效应及其影响因素,研究表明:工业企业生态效率评价值整体高于科技创新综合评价值,且两者综合评价值和两者耦合协调度呈不断增长及东部>中部>西部态势;企业规模、能源结构、研发资金投入和环境规制对各地区工业企业生态效率和科技创新耦合协调度都会产生影响,并且随着滞后期数增加,对耦合协调度影响均趋于稳定。

Study on the Coordination and Influencing Factors of Ecological Efficiency and Scientific and Technological Innovation of Industrial Enterprises

This article takes the industrial enterprises in 29 provinces in China as the research object from 2004 to 2017. By constructing an evaluation index system of ecological efficiency and technological innovation, and using a coupling coordination model and a VAR model, this paper studies and analyzes the coupling and coordination effects and their influencing factors of industrial enterprises. The results show that: The comprehensive evaluation value of industrial enterprises'' ecological benefits is higher than the comprehensive evaluation value of scientific and technological innovation. The comprehensive evaluation value and the degree of coupling and coordination between the two are constantly increasing, and the eastern part> central part> western part, Their growth rate is also Eastern> Central> Western Enterprise scale. energy structure, investment in research and development, and environmental regulations all have an impact on the degree of coupling and coordination of industrial enterprises'' ecological efficiency and technological innovation in various regions. As the number of lags increases, their impact on the degree of coupling and coordination has stabilized.
