摘　　要：本文基于两条竞争的“公司+农户”农产品供应链,考虑质量改进具有边际收益递减和边际成本递增规律,分析投资主体、供应链竞争强度、市场价格质量敏感度、控本能力等多个因素对决策的影响,识别促进质量改进并实现供应链参与者双赢的博弈均衡特征和占优均衡。研究发现:(1)在没有竞争的情况下,供应链应该通过投资改进质量;在有竞争时,供应链是否投资取决于两条供应链的控本能力差异。如果差异较大,能力弱的供应链应选择不投资。(2)当两条供应链采用不同的提质策略时,竞争强度、价格质量敏感度和提质者控本能力的增加都会扩大双方的利润差距。(3)投资主体和质量改进决策主体保持一致的决策机制能够保证投资的激励相容,促使供应链成员主动投资从而改进质量。(4)竞争能够降低供应链非合作代价,提升供应链效率。With the construction of a moderately prosperous society in an all-round way in China,people's living standards have been improved unprecedentedly,and the market demand for green and high-quality agricultural products is also increasing.The continuous improvement of the quality of agricultural products will become a future development trend.This paper investigated quality investment strategies in contract agriculture based on the following considerations.1) Although improvement of the quality of agricultural products can improve the consumer experience and prompt consumers to pay higher prices,the price increase will decrease marginally with the quality improvement.2) Quality improvement increases the marginal cost of production.3) There is an extensive competition between products.Based on these three assumptions,we constructed a quality improvement investment model of two competitive “company + farmer”supply chain.Then,game analysis methods were used to explore how multiple factors such as investor willingness,supply chain competition intensity,cost control ability and quality sensitivity of market prices affect quality improvement investment decisions.Apart from that,we specifically looked at the following questions:1) When does the supply chain need to adopt a quality improvement strategy? When are other strategies more appropriate? 2) When different quality strategies are adopted from competing supply chains,how will changes in the external market affect the two supply chains;3) When quality improvement is conductive to improving supply chain profits,what decision-making mechanism can ensure that supply chain members are willing to invest.In the mathematical analysis model,a two-part price function was used to simulate the diminishing marginal utility of product quality improvement and the intensity of competition between supply chains.Likewise,the increase of marginal cost was simulated using a two-part cost function.Besides,the interaction between the company and farmers was simulated as a company-led
