摘　　要：采用数据包络分析(DEA)—Tobit两阶段模型法,对西部地区的环境投资效率及其影响因素进行实证分析。结果表明,在DEA核算期(2003—2010年)内,西部地区的环境投资效率与中国平均水平相近,且均远高于东部地区;2003—2010年,西部地区全部处于纯技术有效和规模有效的省份只有广西和贵州,而其他省区均不同程度地存在纯技术无效或规模无效现象,这些省区不仅存在环保投资资金管理和经营水平上的非有效性,而且其环境治理投入规模也存在非合理性;对环境投资效率的影响因素进行Tobit回归分析后发现,经济规模和产业结构对环境投资效率有正向促进作用,对外贸易程度、政府规制和公民环保意识与环境投资效率则存在负相关关系。The efficiencies of environmental investment and its influencing factors in Western China were ana- lyzed by DEA-Tobit two phase model. The estimation results showed that： the average efficiencies of Western China were significantly greater than Eastern China,and slightly higher than the national level during the DEA accounting period （2003-2010）. In 2003-2010, only Guangxi and Guizhou were in the efficient production frontier.And other prov- inces all have different degreed of invalid in VRS technical efficiency or scale efficiency. These provinces were invalid in not only the environmental investment fund management and operating levels, but also the environmental invest- ment scale. Besides,the analysis results of factors influencing investment efficiencies showed that., economic condi- tions, tertiary industry proportion had significantly positive influence on investment efficiencies, while the value of im- port or export,the government regulation and the citizen environmental consciousness all had a negative relationship with investment efficiencies.
