【摘要】 在全球经济一体化的市场中,供应链成为了竞争的主体,体现供应链竞争力的要素有四:成本、质量、反应速度和服务,而成本、质量和速度主要受革新和质量控制机制的影响。供应链中革新和质量控制主要存在于生产环节,且革新和质量控制的绩效主要取决于企业之间的渠道合作机制。关于革新和质量控制的渠道合作机制是目前供应链运作效率研究中的较薄弱的环节。本论文运用博弈论和信息经济学的思想和方法,研究二级供应链中供应商和制造商在革新和质量控制两个方面的合作机制。论文首先描述了供应链中存在的委托—代理问题,通过构建并分析不完全信息动态模型,刻画了供应链战略合作伙伴关系得以长期维持的条件和有效运作的激励机制。其次,研究固定市场需求和变动市场需求两种需求状态下,供应商和制造商在供应商革新中的合作机制,通过均衡分析和相关因素研究,得到了均衡的合作机制,开始合作时间、供应链存续时间、供应商的革新能力以及市场需求弹性等要素对合作策略、合作效率的影响。第三,研究供应商面对刺激制造商革新投入和根据市场需求变化调整批发价格这个两难问题时的四种制造商革新合作策略;建立需求临界值方程,确定导致供应商合作策略变化的需求波动参数;研究使供应链系统性能得到改善的均衡方法和合作策略。最后,研究完全信息和不完全信息两种情况下,供应商和制造商在供应链的产品质量控制中的博弈均衡,得到质量合同的参数刻画以及两种信息状态下的合同参数的差异,确定信息成本对合作策略和效率的影响。论文的主要创新有:构建了供应商革新的动态博弈模型,得到了供应商革新合作的存在条件、不同市场结构下的合作策略和相关要素对合作效率的影响;深化和完善了G-C 模型,得到了制造商革新合作中供应商策略转变的临界方程,研究了优化供应链性能的合作模式;构建了供应链质量管理的动态博弈模型,得到了完全信息和不完全信息状态下的质量合同的参数刻画和信息成本对合作策略和效率的影响。更多还原

【Abstract】 In the global integrative economic market, supply chain has become the competitive principal part. There are four factors that incarnate the competitive abilities of supply chain --cost, quality, reactive speed and service, while the first three factors are mostly affected by the mechanisms of innovation and quality control. The mechanisms of innovation and quality control in supply chain exist mostly in the phases of production, and the achievement of innovation and quality control is mostly affected by the channel cooperative mechanism between the corporations. Currently, the channel cooperative mechanisms about innovation and quality control are the weaker link of the study on the operational efficiency in supply chain. This paper studies the cooperation mechanisms of innovation and quality control between a supplier and a manufacturer in a two-class supply chain by using of the thought and method of game theory and the information economics. At first, the paper describes the principal-agent problem in the supply chain management, depicts the conditions for fellowship to efficiently maintain in long-term and the mechanism for facilitate to operate effectively by designing and analyzing a dynamic model with incompletion information. Secondly, paper studies the mechanism of supplier-manufacturer cooperation for the supplier innovation under both the fixed and vary market demand, me show that the effort to cooperative strategy and efficiency resulting from the factors such as the time of beginning, the length of supply chain keep, the ability of supplier’innovation and the flexibility of market demand by analyzing the equilibrium and studying the key factor. Thirdly, the paper seeks to the supplier’s four strategy in manufacturer’innovation when he face the problem that analyses stimulate the manufacturer’investment of innovation or adjust the wholesale price according to the market demand; and set up the critical function of demand, find the parameters of demand which cause of supplier’optimal strategy change; study the way and cooperative strategy that can cause the performance of the manufacturer and the supply chain be improved. Finally, the paper studies the game equilibrium of product quality control between a supplier and a manufacturer in supply chain under both the complete and incomplete information, and finds the parameter depict of the quality contract, as well as the difference of the contract parameter of two kinds of information, me show the cost of information how affect the strategy and the efficient of cooperation. There are three points innovation in the paper: the first,me establish a dynamic game model to describe the cooperation between a supplier and a manufacturer in supplier innovation, and study the condition that cooperation is existed in supplier innovation, the cooperative strategies in different market structure and the influence of the cooperative efficiency by relative factors; secondly,me deep and perfect the model of G-C , get the critical function of supplier’strategic change in manufacturer innovation, and investigate the cooperative mode that the performance of supply chain is optimized; finally, me develop a dynamic game model of quality control in supply chain, get the parameter depict of the quality contract in complete and incomplete information, show the effect to cooperative strategy and efficient resulting from information cost.更多还原
