摘要: Green innovation is an important driving force to promote the sustainable development of urban society and economy. This paper constructs evaluation index system containing social undesirable outputs, uses Super-SBM model Malmquist-Luenberger evaluate green efficiency in 42 cities along Yangtze River Economic Belt from 2013 2017. Additionally, spatial autocorrelation analysis used study correlation efficiency. Finally, coupling coordination degree between high-tech industries. The following results were obtained. (1) average value increased 1.0446 1.0987, annual growth rate total factor productivity was 1.1%. (2) had a significant positive correlation, but types agglomeration among different sections quite different. (3) level industries basic stage. Based on research results, we suggest that this belt further enhance interactive relationship economic coordinated economy society.
