摘　　要：本文利用2007—2017年我国30个省市(因数据缺失,不包括西藏地区和港澳台地区)的面板数据,采用超效率DEA模型测度我国生态效率,同时运用熵权法测度我国科技金融指数,在此基础上建立空间计量模型,研究科技金融、产业结构优化及其交互作用对生态效率的影响。结果表明:我国生态效率整体呈上升趋势,区域差异明显,且生态效率具有显著的空间溢出效应;科技金融在产业结构的调节下对生态效率产生显著的促进作用;产业结构优化对生态效率的影响具有不确定性。By using 2007‐2017 panel data of 30 provinces and cities in China,super efficiency DEA model is made to measure the ecological efficiency.At the same time,the entropy weight method is used to measure the financial index of science and technology in our country.Based on the spatial econometric model,science and technology,financial,industrial structure optimization and the influence of interaction of ecological efficiency are studied.The results show as follows.The overall ecological efficiency in China is rising,and the regional differences are obvious,and the ecological efficiency has a significant spatial spillover effect.Under the regulation of industrial structure,sci‐tech finance has a significant promoting effect on ecological efficiency.The effect of industrial structure optimization on ecological efficiency is uncertain.
