不同的定价方式和定价参数的选择对于承包商会起到不同程度的激励作用。为提高装备采购效益,在承包商追求效用最大化假设的基础上,建立了装备采购完全信息动态博弈模型。对价格、成本、承包商努力程度和承包商效用之间的关系进行了研究,证明了成本分担和固定价格的定价方式能够有效激励承包商提高自身努力水平降低成本,并提出了2种定价方式的参数定量计算方法。 The choice of different pricing and pricing parameters can have different levels of incentives for the contractor. In order to improve the efficiency of equipment procurement, based on the assumption of utility maximization by contractors, a dynamic game model of equipment procurement complete information was established. It studies the relationship between price, cost, contractor’s effort and contractor’s utility, and proves that the cost-sharing and fixed-price pricing method can effectively encourage contractors to improve their own efforts and reduce costs, and proposes two pricing methods The method of quantitative calculation of parameters.
