农产品供应链上各个利益主体的努力水平是终端农产品质量安全水平的重要影响因素。以演化博弈为分析工具,在农超对接的经济背景下,以农民专业合作组织群体和以超市为主体的零售商群体为研究对象,引入质量努力参数刻画双方质量努力策略,通过其演化均衡考察合作组织与超市策略变化过程和趋势。研究发现:合作组织和超市质量策略会出现三种均衡,体现了不同发展阶段合作组织与超市的策略变化。同时,恰当的政府激励会促使农超供应链质量努力水平向高水平移动。
Effort of various parties in an agricultural supply chain is vital to agricultural product quality and safe- ty. This paper studies retailers represented by specialized farmer cooperative organizations and supermarkets by establishing evolutionary game models considering quality effort based on agriculture-supermarket supply chain. Meanwhile, evolutionary stable strategies are given under government incentives. It is shown that at different de- velopment stages of the chain, the government should give different incentives. Furthermore, appropriate govern- ment incentives will promote the quality of agricultural supply chain to a high level.
