中文摘要：

以两条包含一个制造商和一个零售商的供应链为研究对象，讨论了两供应链采用不同决策结构时链间Stackelberg博弈问题，并对链间博弈四种决策结构（分散一分散、分散一集中、集中一分散、集中一集中）进行比较分析。研究结果表明，1）对于领导者供应链来说，集中决策是其占优策略；2）对于追随者供应链来说，采用集中决策还是分散决策，则取决于产品可替代性的高低和领导者供应链的选择；3）当产品替代度较低时，集中一集中结构是链间单次和多次重复博弈的均衡解；当产品替代度较高时，集中一分散结构是链间单次博弈均衡解，而分散一分散结构则是多次重复博弈均衡策略。

英文摘要：

By taking two supply chains as a research object, each of them containing one manufacturer and one retailer, the prob- lem involving Stackelberg game is discussed, when two supply chains adopt different decision structures, respectively. In particu- lar, four decision structures between these two supply chains are analyzed, including the structures of decentralized -decentral- ized, decentralized - centralized, centralized - decentralized, centralized - centralized. It is found that （ l ） centralized decision is the dominate strategy for the leader supply chain ; （ 2 ） as for the follower supply chain, whether adopting centralized decision or decentralized decision, it is depended on the substitutability degree of products and the selection of the leader supply chain ; （ 3 ） when the substitutability degree of product is low, the structure of centralized - centralized is the equilibrium solution of single and repeat games ; and when the substitutability degree of product is high, the structure of centralized - decentralized is the equi- librium solution of single game ; while the structure of decentralized - decentralized is the equilibrium solution of repeat games.
