本文强调了合作质量投资（CQI）策略的重要性，并提出了一个简单的比例投资共享计划在外包的供应链，其中包括一个合同制造商（CM，供应商）和两个竞争的原始设备制造商（OEM，买家），其需求是敏感的价格和产品质量。一个三阶段的动态博弈理论框架被用来描述每个实体的决策。具体来说，我们分析了质量选择的三种可能的决策结构：CM最佳设置产品质量，以及两个OEM合作或非合作设置产品质量。通过逆向归纳法，我们得到了每个决策方案的分析均衡解。我们确定，CM的质量投资费用的份额是足够大的，和CQI战略将有利于质量的提高，无论谁设置的产品质量水平。相对于均衡收益（利润），这项研究表明，CM总是喜欢有完全控制的质量选择时，有实施的CQI策略，而OEM总是受到这种策略的伤害，除了当他们合作的质量决策与一个相当大的CM份额。此外，通过实施CQI战略，可以提高整个供应链的利润。此外，我们明确提出了实现这种改进的条件。
This paper highlights the importance of having a cooperative quality investment (CQI) strategy and proposes a simple proportional investment sharing schedule in the outsourcing of a supply chain, which consists of a contract manufacturer (CM, the supplier) and two competitive original equipment manufacturers (OEMs, the buyers), the demands of which are sensitive to both price and product quality. A three-stage dynamic game-theoretic framework is applied to describe decisions of every entity. Specifically, we analyze three possible decision structures for the quality choice: the CM optimally sets the product quality, and two OEMs cooperatively or noncooperatively set the product quality. By the backward induction approach, we obtain the analytical equilibrium solutions for each decision scenario. We determine that the CM׳s share of quality investment expenses is sufficiently large, and the CQI strategy will be beneficial to quality enhancement regardless of who sets the product quality level. With respect to the equilibrium payoffs (profits), this study shows that the CM always prefers to have complete control of the quality choice when there is implementation of the CQI strategy, while the OEMs are always hurt by this strategy, except when they cooperate on the quality decision with a rather large CM share. In addition, the whole supply chain׳s profit can be improved by practicing the CQI strategy. Furthermore, we explicitly propose the conditions for realizing this improvement.
