摘要
在政府和社会资本合作(public-private partnership,PPP)项目中,项目公司具有两种施工任务外包模式,一是纵向外包模式,即将施工任务外包给项目公司成员之外的承包商,二是横向外包模式,即将施工任务外包给项目公司成员.在任一外包模式下,项目公司均可以采用固定总价合同或成本加酬金合同.本文研究项目公司对于合同类型及施工外包模式的选择问题,通过建立项目公司与承包商的Stackelberg博弈模型,发现项目公司对于合同类型的选择取决于固定总价合同和成本加酬金合同下的固定报酬之差,当该报酬差足够大时,项目公司应当选择成本加酬金合同,否则,应当选择固定总价合同.进一步分析了影响项目公司合同类型选择的关键因素,包括项目单位时间的运营收益以及成本加酬金合同下的激励系数等.关于两种外包模式之间的比较,研究发现横向外包模式能给项目公司带来更高的收益.
In public-private partnership(PPP)projects,when the project company contracts out the construction task,it can adopt either the horizontal outsourcing model or the vertical outsourcing model,under the former of which the project company contracts with a contractor who is not the member of the project company while under the latter the project company contracts with one of its members.No matter which outsourcing model is used,the contract type can be either the fixed price contract or the cost plus contract.We study the decision of the project company on contract type and outsourcing model.By building a Stackelberg game model between the project company and the contractor,we find that the project company's decision on contract type depends on the difference between the fixed payment to the contractor under the two contract types.Specifically,if the difference is sufficiently large,then the cost plus contract should be adopted and otherwise,the fixed price contract adopted.We have further analyzed key factors in affecting the project company's decision including the operation revenue in unit time and the incentive coefficient under cost plus contract.Regarding the comparison between the two outsourcing model,we find that horizontal outsourcing typically leads to higher benefi ts for the project company.
