本文考虑一个风险中性的节能服务公司和一个风险规避的用能企业在节能成本上具有不对称信息,采用一个能源费用节约额的线性函数作为用能单位向节能服务公司的支付,建立了一个斯坦伯格博弈模型来研究节能服务外包合同的设计。研究发现最优合同是效益保证和效益共享两种形式的结合,即节能服务公司向用能单位支付一个保证的节约额,然后双方共同对最后实现的能源费用节约额进行分享,且保证节约额和节能服务公司的分享比例随节能服务公司的效率、节能绩效的不确定性和用能单位风险规避程度的增加而增加。
本文攷慮一箇風險中性的節能服務公司和一箇風險規避的用能企業在節能成本上具有不對稱信息,採用一箇能源費用節約額的線性函數作為用能單位嚮節能服務公司的支付,建立瞭一箇斯坦伯格博弈模型來研究節能服務外包閤同的設計。研究髮現最優閤同是效益保證和效益共享兩種形式的結閤,即節能服務公司嚮用能單位支付一箇保證的節約額,然後雙方共同對最後實現的能源費用節約額進行分享,且保證節約額和節能服務公司的分享比例隨節能服務公司的效率、節能績效的不確定性和用能單位風險規避程度的增加而增加。

Information asymmetry on energy saving cost between a risk-neutral energy service company and a risk-averse client is taken into account. A linear function of the total realized energy savings is employed as the payment from the client to the company, and a Stackelberg game model is developed to design the optimal contract in energy service contracting. The research shows that the optimal contract integrates both guaranteed savings and shared savings, which means that the energy service company pays a guaranteed savings to the client and then the realized savings is shared by both parties. Moreover, both the guaranteed savings and the sharing proportion of the company from the total realized energy savings increase as the efficiency of the company, the uncertainty of the energy service performance and the degree of risk aversion of the client increase.
