摘 要:环境污染治理投资是生态环境保护的资金来源,其投资规模和投资形式对生态效率产生着重大影响。本文构建生态效率测度指标和非期望的超效率SBM模型,测定了长江经济带9省2市的生态效率水平,再利用Tobit模型量化研究环境污染治理投资的总量及各投资形式对生态效率的影响程度,得出长江经济带环境污染治理投资对生态效率具有正向影响但影响程度一般,3种环境污染治理投资类型中的当年完成环保验收项目环保投资对生态效率影响程度最大且显著。Environmental pollution management investment is capital source of eco-environmental protection,its investment sizes and forms play a large role in ecological efficiency.This paper establishes a SBM model based on ecological efficiency indicators and non-expected ultra-efficiency,estimates their ecological efficiency level in 9 provinces and 2 cities along the Yangtze River economic zone,and uses Tobit model to quantitatively study the impacts of the total investment and all forms of environmental pollution management on ecological efficiency.It concludes that this impact is positively at a normal level.Environmental protection investment completed and accepted within the current year plays outstandingly the largest influence on ecological efficiency.
