In order to solve the problem of information asymmetry in the traditional price transaction mode and the high transaction cost and divide the market into local market of bargaining transaction mode of logistics information platform, this study designs a bilateral bidding transaction mode to improve the efficiency of the logistics information platform matching transaction. Based on the programming model, in accordance with the characteristics of logistics service procurement, a new trading mechanism is designed, in which the supply and demand matching rules maximize social welfare under the bilateral bidding structure, and improved the classic VCG payment rules, the new payment rules make the mechanism meet the budget balance constraint. The bilateral bidding transaction mode encourages traders to tell the truth and meet the rational constraints of participation. Compared with the traditional trading mode, the bilateral bidding trading mode designed in this study can match the transaction more quickly and make the logistics resource allocation better.%为解决物流信息平台传统标价交易模式存在信息不对称,而议价交易模式存在交易成本过高及将市场分割为局部市场的问题,设计双向竞标交易模式来提升物流信息平台撮合交易的效率.针对物流服务采购的特点,基于规划模型设计双边报价结构下使得社会福利最大化的供需匹配规则,改进了经典VCG支付规则,新的支付规则使得机制满足预算平衡约束,该交易模式鼓励交易者说真话,满足参与理性约束.通过理性及仿真分析得出,与传统交易模式相比较,该交易模式能更快速撮合交易,并使得物流资源配置更优.
