【摘要】：近年来,陕西省生态环境所面临的威胁日益严重,通过PPP (政府和社会资本合作)模式引导社会资本与政府合作参与生态环境保护投资,可以有效促进陕西省生态环境商品的市场化供给。因此从PPP视角对陕西省生态环境保护投资效率进行评价,不仅有助于从宏观层面把握PPP视角下陕西省生态环境保护投资整体效率的发展,也有助于从微观层面明晰PPP模式下生态环境保护各方参与主体的投资绩效,为陕西省在生态环境保护领域PPP模式的发展提供指导,从而促进陕西省生态环境保护市场化的发展。本文从PPP视角对陕西省生态环境保护投资效率进行研究,首先,概述了本文的研究背景和意义,并且针对研究所涉及的相关概念和理论,以及国内外相关文献分类进行详细阐述,为本文后续研究内容的展开奠定了理论基础。其次,从PPP模式下陕西省生态环境保护的发展历程、政府生态环境保护投资现状、社会资本生态环境保护投资现状、陕西省生态环境保护投资产出效益,以及陕西省生态环境保护存在的问题等五个层面对PPP视角下陕西省生态环境保护投资和产出现状进行分析。再次,结合陕西省2009-2014年面板数据,通过实证模型探究了 PPP视角下陕西省生态环境保护投资和产出的相关性,而且从投资效率和敏感性两个角度对PPP视角下陕西省生态环境保护投资进行全面的分析和讨论。通过研究发现:①陕西省政府财政支出和社会资本投资对生态环境保护投资环境产出和经济产出具有显著的正向促进效应,而对生态环境保护投资民生产出的相关性并不显著。②陕西省各市区生态环境保护投资效率差异较大,其中咸阳市和榆林市从2009-2014年每一年都处于DEA有效状态;陕西省生态环境保护投资效率从2009-2014年呈现退步趋势。③关中地区各城市生态环境保护投资效率对政府生态环境保护财政支出的敏感性相对最高,陕南地区各城市次之,陕北地区各城市相对最小;陕北地区各城市生态环境保护投资效率对社会资本投资的敏感性相对最高,关中地区各城市次之,陕南地区各城市相对最小。最后,从加快政府生态环境保护职能的转变、突破社会资本参与生态环境保护的市场壁垒、改善社会资本参与生态环境保护投资的规模和结构以及强化政府对生态环境保护PPP项目的监督管理等四个方面分析了提高陕西省生态环境保护投资效率的路径。
[Abstract]:In recent years, the threat to the ecological environment in Shaanxi Province is becoming more and more serious. Through the PPP (Government and Social Capital Cooperation) model, social capital and government cooperate to participate in the investment of ecological environment protection.It can effectively promote the market supply of environmental commodities in Shaanxi Province.Therefore, to evaluate the investment efficiency of ecological environment protection in Shaanxi Province from the perspective of PPP is not only helpful to grasp the overall efficiency development of ecological environment protection investment in Shaanxi Province from the macro level, but also from the perspective of PPP.It also helps to clarify the investment performance of all parties involved in ecological environmental protection under the PPP model at the micro level, and to provide guidance for the development of PPP mode in the field of ecological environment protection in Shaanxi Province, thus promoting the development of marketization of ecological environmental protection in Shaanxi Province.This paper studies the investment efficiency of ecological environment protection in Shaanxi Province from the perspective of PPP. Firstly, it summarizes the research background and significance of this paper, and aims at the related concepts and theories involved in the research.The classification of relevant literature at home and abroad is elaborated in detail, which lays a theoretical foundation for the following research.Secondly, from the development course of ecological environment protection in Shaanxi Province under PPP mode, the present situation of government ecological environment protection investment, social capital ecological environment protection investment present situation, the output benefit of Shaanxi province ecological environment protection investment.And the problems of ecological environment protection in Shaanxi Province are analyzed from five aspects: investment and output status of ecological environment protection in Shaanxi province under the perspective of PPP.Thirdly, based on the panel data from 2009 to 2014 in Shaanxi Province, this paper explores the correlation between investment and output of ecological environment protection in Shaanxi Province from the perspective of PPP.Moreover, from the angle of investment efficiency and sensitivity, this paper makes a comprehensive analysis and discussion on the investment of ecological environment protection in Shaanxi Province from the perspective of PPP.It is found that the fiscal expenditure and social capital investment of the Shaanxi Provincial Government have a significant positive promoting effect on the ecological environment protection investment environment output and economic output.However, the correlation of ecological environment protection investment and livelihood output is not significant. 2. The investment efficiency of ecological environment protection in different urban areas of Shaanxi Province is quite different, among which Xianyang and Yulin cities are in the effective state of DEA every year from 2009-2014;The investment efficiency of ecological environment protection in Shaanxi Province showed a trend of retrogression from 2009-2014. 3 the sensitivity of investment efficiency of ecological environment protection in Guanzhong area to the government expenditure on ecological environment protection was the highest, followed by the cities in southern Shaanxi province.The sensitivity of investment efficiency to social capital is the highest in northern Shaanxi, followed by the cities in Guanzhong and the cities in southern Shaanxi.Finally, in order to accelerate the transformation of the government's function of ecological environment protection and break through the market barrier of social capital to participate in the protection of ecological environment,This paper analyzes the ways to improve the investment efficiency of ecological environment protection in Shaanxi Province from four aspects: improving the scale and structure of social capital participating in the investment of ecological environment protection and strengthening the supervision and management of the PPP project of ecological environment protection by the government.
