摘　　要：合同节水是重要的节水措施,效益分享型合同节水是合同节水项目的重要类型,但对效益分享期、节水投资与节水量等合同参数的取值范围尚缺少理论分析,制约合同节水项目的有效实施。利用工程经济学的方法,在构建用水户和节水服务公司的收益净现值函数的基础上,以用水户和节水服务公司均能获得预期收益为目标,提出了适宜的效益分享期、节水投资与节水量范围的分析方法。基于两个高校合同节水案例对该方法进行了验证,并分析了用水户和公司收益对折现率、成本利润率和效益分享期的敏感性。结果表明该方法能有效评价合同节水项目的合理性,期望成本收益率是影响合同节水收益最重要的参数。进而提出了合同节水项目招标和项目后评估框架。该研究可为效益分享型合同节水项目招标和评估提供参考。Water Saving Management Contract(WSMC)is an important water conservation measure,and the benefit-sharing contract is an important type of WSMC project.But there is a lack of theoretical analysis on the range of contract parameters such as benefit-sharing period,water-saving investment,and water-saving volume,which restricts the effective implementation of WSMC projects.We use engineering economics to construct the benefit net present value function for water users and water conservation service companies and propose a suitable analysis method for the range of benefit sharing period,water saving investment,and water saving volume based on the goal that both water users and water conservation service companies can obtain the expected benefits.Based on two university WSMC cases,the method was validated,and the sensitivity of water users'and companies'benefits to the discount rate,expect cost margins,and benefit-sharing period was analyzed.Results show that the method is effective in evaluating the reasonableness of WSMC projects,and expect cost margin is the most important variable affecting the benefits of WSMC.Frameworks for the bidding and evaluation of WSMC projects are proposed.The study can provide a reference for the bidding and evaluation of benefit-sharing WSMC projects.
