食品安全 购买行为 质量投入
食品安全 購買行為 質量投入
식품안전 구매행위 질량투입
food safety consumer behavior investment on quality
运用演化博弈理论分析了食品安全事件发生后消费者购买行为的演变趋势,研究结果表明:当国产食品在事件前就处于竞争劣势时,事件后消费者会逐渐倾向于购买进口食品直至进口食品完全占领国内市场;当国产食品在事件后还具备竞争优势时,无论生产者是否解决潜在的质量安全问题,消费者都会倾向于购买国产食品,但监管者加强监管力度会增进消费者福利、减少生产者福利;当事件前后国产食品由竞争优势转为竞争劣势时,如果监管力度较弱,消费者会逐渐倾向于购买进口食品,如果监管力度较强,则取决于事件前的消费者群体的购买行为和生产者群体的质量投入行为。
運用縯化博弈理論分析瞭食品安全事件髮生後消費者購買行為的縯變趨勢,研究結果錶明:噹國產食品在事件前就處于競爭劣勢時,事件後消費者會逐漸傾嚮于購買進口食品直至進口食品完全佔領國內市場;噹國產食品在事件後還具備競爭優勢時,無論生產者是否解決潛在的質量安全問題,消費者都會傾嚮于購買國產食品,但鑑管者加彊鑑管力度會增進消費者福利、減少生產者福利;噹事件前後國產食品由競爭優勢轉為競爭劣勢時,如果鑑管力度較弱,消費者會逐漸傾嚮于購買進口食品,如果鑑管力度較彊,則取決于事件前的消費者群體的購買行為和生產者群體的質量投入行為。

This paper applies evolutionary game theory to the analysis of the evolution trend of consumers' buying behaviors after the food safety incidents. The results show that when the domestic food is in the place of competitive disadvantage before the incidents,the consumers tend to buy imported food gradually and the imported food will completely occupy the domestic market. When domestic food still has the competitive advantage after the incidents,consumers tend to buy domestic food no matter whether domestic food producers have solved the potential food safety problems or not,however,regulators' strengthening force in supervision would enhance the consumer's welfare but reduce the producer's. When domestic food is transformed into competitive disadvantage from competitive advantage after the incidents,consumers will gradually tend to buy imported food if the supervision force is weak; on the other hand,if the supervision force is strong,it depends on the buying behavior of the consumer group and the quality investment behavior of the producer groups before the incidents.
