基于声誉效应的跨流域生态补偿演化合作机制分析

跨流域生态补偿是提升生态资本价值、保护流域生态环境、促进区域可持续发展的重要手段。基于政府在对具备社会环境效益、影响公众利益的生态补偿项目决策和实施过程中产生声誉问题，通过对水源地和受水区的博弈情景设定，在考虑损失成本、生态收益以及转移支付等显性利益因素的同时，将声誉等隐性因素考虑在内，引入流域管理机构和政府声誉函数，构建生态补偿演化博弈模型，探讨水源地和受水区地方政府之间的博弈演化过程及影响因素，并利用Matlab软件进行仿真研究，分析各参数的变化对利益相关主体行为策略选择的影响程度。研究表明，双方合作的演化方向主要受奖惩力度、水源地保护成本、受水区转移补偿金额、治污效益、声誉转化效益等10个因素的影响，并提出强化流域管理机构职能、提高公众和企业的环保意识、构建声誉水平评价机制以及构建多元化生态补偿途径等对策建议。

COOPERATIVE MECHANISM OF TRANS-STREAM ECOLOGICAL COMPENSATION EVOLUTION BASED ON REPUTATION EFFECT

Trans-stream ecological compensation is a vital means to improve ecological capital values, protect stream ecology and promote regional sustainable development. Governments will bear issues of reputation during making decision and conduction of ecological compensation projects which are of social environmental benefits and public interests. This paper sets the gaming scenarios of water source and water reception, and incorporates loss cost, ecological gain, transfer payment, and reputation as well to establish an ecological compensation evolution gaming model in discussing their gaming evolution process and factors between water source and water reception by means of stream managing administration and governmental reputation function. Matlab is used to analyze the influence of parameter changes on stakeholder's selection. Ten factors impacting the cooperation evolution include rewards and punishment, water source protection cost, water reception transferred compensation payment, pollution treatment benefits, reputation-converted benefits. This paper presents suggestions on intensifying stream administrative functions, raising public and enterprise's awareness of environmental protection, establishing reputation evaluation mechanism and setting up multiple ecological compensation paths.
