摘要 以单共享资源为背景,允许自利的需求个体具有不同的正规型或非正规型目标,采用排序博弈研究共享各方在无秩序代价(Price of Anarchy,POA)衡量下的供需匹配程度。对于多人多目标模型,先证明一般意义下以及满足EDD规则的Nash均衡和Pareto解有相同的POA,继而给出了两种不同共享方指标下的POA的解析表达,并进行了对比分析。研究发现:非正规型客户是导致共享经济中供需失配的关键因素之一,但其给两种共享方指标下的供需匹配带来的影响是不同的,且与直觉相反,Pareto改进以及EDD规则并不能带来改善。这些发现对于解释共享经济中供需匹配机理并提升共享效率有着重要的指导意义。 based on single shared resource,supply-demand matching could be evaluated by the Price of Anarchy(POA),which were studied by utilizing sequencing game,considering multiple selfish tasks had different regular or non-regular objectives. For such multi-person multi-objective model, it was proved that the general Nash Equilibrium solutions, Pareto solutions, and the corresponding solutions satisfying EDD rule had the same POA.Two POAs under two objectives of shared resource providers were given and compared.It was found that non-regularity was one of the key elements to deteriorate the supply-demand match,but its impacts on supply-demand match were different under two objectives of resource providers. Moreover,it was counter-intuitive that Pareto improvement and EDD rule could not alleviate these impacts.These findings could help to explain the matching mechanism of supply-demand in sharing economics and improve the sharing efficiency.
