摘　　要：从考虑污染变量角度运用SE-DEA模型对河南省2007-2012年的生态效率进行静态评价,通过Malmquist指数分析了生态效率的动态变化趋势,并结合Tobit回归探讨了生态效率的影响因素。结果表明:2007-2012年河南省生态效率(静态)总体上呈平稳上升趋势;河南省各地市(洛阳、许昌除外)生态效率(动态)呈现随时间进步特征,生态效率的改善主要是技术进步的作用所致,受技术效率变动影响较小;经济规模和产业结构是阻碍生态效率提高的主要因素,而市场化程度显著促进了生态效率的提高;环境保护支出对生态效率有明显的促进作用;进出口贸易和外商投资分别对生态效率产生一定的负向和正向影响。The static evaluation on the eco-efficiency in Henan Province from 2007 to 2012 was conducted by using the SE-DEA model with the analysis of dynamic variation trends of eco-efficiency by Malmquist index and the discussion of the influence factors of eco-efficiency combined with Tobit regression analysis method. The research suggested that eco-efficiency（static） presented an overall steady increasing trend in Henan Province during the period from 2007 to 2012. All cities except Luoyang and Xuchang of Henan Province had eco-efficiency（dynamic） gradual improvements with time, which mainly resulted from the technical progress. Continuous expansion of the economic scale and the existing old industrial structure were the main factors that hindered eco-efficiency improvement while the marketization apparently encouraged the upgrading of it. Expenditures for the environmental protection could remarkably influence eco-efficiency. Import-export trade and the foreign investment had influences on the eco-efficiency in both negative and positive ways.
