Abstract:This paper uses the panel data of 30 provinces and cities in China from 2007 to 2017, uses the super-efficiency DEA model to measure China"s ecological efficiency, and uses the entropy weight method to measure China"s science and technology and financial index. Based on this, a spatial measurement model is established to study science, technology, finance, and industry Impact of structural optimization and its interaction on ecological efficiency. The results show that China ’s overall ecological efficiency is on the rise, regional differences are obvious, and ecological efficiency has a significant space spillover effect; technological finance has a significant promotion effect on ecological efficiency under the adjustment of the industrial structure; and the impact of industrial structure optimization on ecological efficiency Uncertain.
