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.
