基于动态收益的水电开发利益分配模型

Benefit-sharing in hydropower projects:A mathematical model based on dynamic rate

水库移民问题的本质是利益分配问题,需要通过水电开发利益重分配加以解决。该文通过引入动态收益率评判指标,建立了水电开发利益分配数学模型,给出了实现目标收益率情况下移民补偿和水电上网电价的试算求解法以及不同边界条件下模型的拓展形式;应用建立的模型,对中国西南地区某大型水电项目进行了案例分析。研究结果表明:当前水库移民是各主要参与方中收益率最低的一方,开发企业和电网企业收益率处于居中位置,而地方投资企业收益率最高;该大型水电项目蕴含着巨大的水能资源经济租空间,完全具备调节移民补偿和水电电价的能力,证明了模型及结果的合理性。该文建立的利益分配模型丰富了移民补偿理论,成果和结论对移民工作和政策制定有指导意义。

Rebuilding the benefit-sharing mechanism is the key to solving problems related tore settling hydropower exploitation.A dynamic rate is used as the evaluation index in the mathematical model for the resettlement compensation and hydroelectricity price for different boundary conditions.The model is applied to the hydropower project in Southwest China as a case study.The results show that migrants get the lowest return among the various stakeholders,hydropower corporations and grid corporations get a moderate level of return,and local investment corporations get the best return.The large economic returns in large hydropower projects allow adjustments of the migrants＇ compensation as well as the hydroelectricity price so this model are useful in practical projects.This model can be used to improve migrant compensation with the conclusions providing guidance and hydropower resettlement policy.
