新疆环境治理投资效率及其影响因素--基于DEA-Tobit模型的实证分析

摘要

This paper applies DEA model to measure the environmental governance investment efficiency of Xinjiang between 2000 and 2014 , and by using the TOBIT model to explore the main factors influencing the environmental governance investment efficiency of Xinjiang. The result shows that the comprehensive technical efficiency of the en-vironmental governance investment efficiency in Xinjiang from 2000 to 2014 is low, the pure technical efficiency and scale efficiency need to rise. In the influence factors of efficiency, the level of economy development has signif-icant positive influence on the environmental governance investment efficiency, while the citizen environmental pro-tection consciousness, the intensity of environmental protection all have a negative relationship with the environmen-tal governance investment efficiency, the other influential factors have not passed the test of significance. In view of this, basing on the environmental governance investment efficiency status of Xinjiang and its influence factors, this paper puts forward some effective suggestions to enhance the efficiency of environmental governance investment of Xinjiang.%论文应用DEA模型来测算新疆2000年—2014各年度环境治理投资效率，并利用Tobit模型来探究影响新疆环境治理投资效率的主要因素。研究结果表明：2000年—2014年新疆环境治理投资的综合技术效率偏低，纯技术效率、规模效率亟须提升；在效率的影响因素中，经济发展水平对新疆环境治理投资效率存在明显的促进作用，而环保意识、环保强度则对其产生显著的负面影响，其余的影响因素未通过显著性检验。鉴于此，基于新疆环境治理投资效率现状及其影响因素，为进一步提高新疆环境治理投资效率提出针对性建议。
