水电工程建设移民搬迁Shapley补偿测算方法

Calculation method of Shapley compensation for reservoir resettlement of hydropower project construction

水库移民补偿金额的合理性直接关系移民自身权益,是水电工程顺利开发的关键。以水库移民和水电开发企业为研究对象,系统分析两大利益相关者的成本与收益。将水库移民积极参与合作对水电工程引起的成本收益看作一种合作性收益,通过运用合作博弈中的Shapley值法,综合权衡双方的风险承担度、资源投入度及贡献程度,构建水电工程建设条件下的移民搬迁补偿模型,并对其求解移民所获补偿金额。最后运用该方法对某大型骨干电站移民搬迁补偿金额进行试算。结合案例表明:现行的水库移民补偿方式并未充分考虑水电工程建设所带来的合作效益,不合理的补偿金额极易引发恶劣群体性事件,建议水库移民补偿金额通过合作的视角确定。

Reasonability of the resettlement compensation by a hydropower project is directly related to the immigrants＇ rights and interests, thereby becoming a key factor in successful implementation of the project. This paper examines reservoir resettlement and hydropower development enterprises and presents a systematical analysis on the cost and benefits of these two stakeholders. We consider the cost-benefit caused by a hydropower project in which immigrants actively participate as a cooperative benefit, and develop a resettlement compensation model by using the Shapley value in cooperative game and making a tradeoff between the risk taken, resource investment, and contribution from both sides during project construction. This model can be solved for the sum of compensation for the immigrants, and its calculations are tested through application to a large hydropower station. Calculations show that the current method of calculating reservoir resettlement compensation is not able to give a full consideration of the cooperation benefits brought about by a hydropower project and its unreasonable determination of compensation could easily cause conflicts and even incidents between the two parties. Thus we suggest that the compensation payment of reservoir resettlement should be determined from the perspective of cooperation.
