中文摘要： 竞争供应链之间普遍存在着横向不对称信息，同时下游制造商间常常会共享该信息，以降低它给竞争双方带来的损失。考虑到供应链间既竞争又合作的关系，供应链内部的采购或供应决策会发生怎样的深刻变化？本项目将在几种存在横向不对称信息的典型供应链竞争环境下回答该问题。首先，针对供应链内部信息对称的情形：当上游供应商先动下游制造商跟随时，研究制造商的横向信息共享决策与采购策略；并在横向不对称信息能够被制造商内生努力改变时，探讨制造商的信息共享、努力投入及采购策略间的关系。然后，针对供应链内部存在纵向不对称信息的情形：研究制造商间的横向信息共享对制造商采购甄别合同设计的影响；并探讨供应商供应信号合同设计与制造商间横向信息共享的关系。在竞争供应链间存在横向不对称信息的环境下，本项目致力于建立一套考虑横向信息共享的供应链采购运作理论和方法，从而丰富现有供应链竞争与合作理论，并为企业现实运作提供理论指导。

英文摘要： There is usually horizontal asymmetric information between competing supply chains, and downstream manufacturers often share the information to reduce the profit loss caused by it. Then, how would the supply or procurement decisions be influenced by the cooperation of competing supply chains? This project will answer the above question under several typical supply chain competition environments where horizontal asymmetric information exists. First, considering there is no vertical asymmetric information in supply chains, the project will investigate the manufacturer's horizontal information sharing and procurement decision when supplier and manufacturer join the leader-follower game, and study the manufacturer's dynamic decisions on horizontal information sharing, endogenous effort and procurement strategy when the horizontal asymmetric information can be changed by manufacturer's effort. Second, considering there is vertical asymmetric information in supply chains, the project will research the manufacturer's screening contracts design and horizontal information sharing decision, and explore the supplier's signaling contracts design when horizontal information sharing may happen between manufacturers. The outcomes of the project are expected to generate new theories and methods for supply chain procurement operation management under the coexistence of competition and cooperation between supply chains and help the enterprises develop better practices.
