效益保证型合同节水管理项目的利益分配

Profit Distribution of Benefit Guaranteed Water Saving Management Contract Project

合同节水管理(WSMC)利益分配机制不完善,影响其发展进程。以用户和节水服务公司(WSCO)为参与方,运用分级分成模型研究效益保证型WSMC的利益分配。首先,选取WSCO努力程度、知识投入系数为影响因素,建立双方的收益模型。其次,根据影响因素的变化分析在WSCO仅获得管理费用和WSCO参与超额利润分配这两种情形下,WSCO努力的积极性,并决策超额利润时双方的利润比例。最后,进行算例分析,验证模型有效性。结果表明:(1)WSCO参与超额利润分配时,努力程度更高,项目总利润更高。(2)WSCO工作努力程度分别与知识投入效率系数、超额利润分配比例呈正相关。

The benefit distribution mechanism of Water Saving Management Contract(WSMC)is imperfect,which affects its development process.Taking users and Water Service Companies(WSMC)as participants,this paper studies the benefit distribution of benefit guaranteed WSMC by using the hierarchical sharing model for the first time.Firstly,the degree of WSCO effort and knowledge input coefficient were selected as the influencing factors to establish the income model of both sides.Secondly,according to the change of influencing factors,it analyzed the enthusiasm of WSCO’s efforts in the two cases of WSCO only obtaining management expenses and WSCO participating in excess profit distribution,and determined the profit proportion of both sides when making excess profits.Finally,an example was given to verify the effectiveness of the model.The results show that:(1)When WSCO participates in excess profit distribution,the degree of effort is higher and the total profit of the project is higher.(2)WSCO’s work effort is positively correlated with the efficiency coefficient of knowledge input and the proportion of excess profit distribution.This paper provides a reference for the benefit distribution of WSMC under the benefit guarantee mode.
