摘　　要：针对在线服务外包,研究了供应商投标服务方案(体现服务质量)和价格的买方决定制多属性采购拍卖,分析了交易双方关于服务内容的再谈判对供应商投标均衡、买方初始服务内容决策和各方期望利润的影响。结果表明,无再谈判情形下,供应商的服务质量投标均衡和信息租金都随初始服务内容递增;而有再谈判情形下,尽管买方对服务质量的评标权重随初始服务内容递增,但供应商服务质量、信息租金及买方期望利润都不受初始服务内容影响。换言之,初始服务内容对采购项目的规制作用被再谈判完全替代。不仅如此,相较于无再谈判情形,再谈判的存在能够激励供应商提供更高的服务质量,并促成更多的服务内容成交,最终使买方、获胜供应商和交易平台都获得更高期望利润。Motivated by the rapid growth of the online outsourcing market,a multi-attribute auction model for online service outsourcing is studied,in which multiple potential suppliers bid service quality and service price,and renegotiation may take place after the determination of auction winner.To investigate the effects of service content renegotiation on the players’decisions and expected profits,both a scenario without renegotiation and one with renegotiation are examined and compared.Results show that,without renegotiation,the suppliers’service quality and information rent are increasing inthe initial service contentannounced by the buyer.However,in the scenario withrenegotiation,although the buyer’s weighting of service quality increases inthe initial service content,the suppliers’service quality,information rent and buyer’s expected profits are not affected by the initial service content.In other words,the regulation function of the initial service content is completely substituted by renegotiation.Furthermore,comparisons show that the renegotiation option leads to higher service quality and higher ex post service content,and it makes the buyer,the winning supplier and the platform better off.The study contributes to the literature by providing a buyer-determined auction model for online service outsourcing considering renegotiations,and it provides insights on the value of renegotiation for online service providers,buyers and transaction platforms.
