Coupling coordination degree analysis and driving factors of innovation network and eco-efficiency in China

Green and high-quality development has become an important development path for the global response to climate change. Eco-efficiency and innovation, as important indicator and core driver of green and high-quality development respectively, have attracted wide attention. However, the research on the relationship between innovation and eco-efficiency is mostly qualitative research, and the index selection of technological innovation and eco-efficiency is single. Therefore, this paper from the perspective of quantitative research based on the industrial enterprise data of 30 provinces from 2006 to 2019 to explore the mechanism between innovation network and eco-efficiency by constructing a three-stage evaluation model. The first step is to build the network SBM model to measure the innovation network efficiency, and decomposing it to explore the internal devel-opment and change rules of the innovation. And the SBM with undesirable output model is employed to evaluate the eco-efficiency and analyze the regional heterogeneity. Second, the coupling coordination model is con-structed to quantitatively study the coupling coordination degree between innovation network efficiency and eco-efficiency. Finally, the influencing factors of coupling coordinated degree are discussed. The result shows that the innovation network comprehensive efficiency is lower than that of scientific and technological inno-vation efficiency and transformation of scientific and technological achievement efficiency, and the eco-efficiency of eastern China develops stably and is higher than that of the other three economic zones. Scienti-fic technological innovation and the eco-efficiency of coupling coordination degree is higher than the trans-formation technological achievement and eco-efficiency of coupling coordination degree. Information and communication technology plays an important role in promoting innovation network comprehensive efficiency and eco-efficiency at different systems.
