摘要
针对废弃食品非正规回收市场,非正规回收商数量导致单位回收收益随规模变化不同,分别建立了单位回收收益不变、增加与减少3种情况的非正规回收商预期总利润优化模型,分析了非正规回收商的伪装行动力与回收率决策,以及非正规回收商数量的影响效应。以"僵尸肉"为典型案例进行了数值分析。结果表明:非正规回收商的伪装行动力与废弃食品回收率都分别受到废弃食品数量、伪装概率和废弃食品出售价格的正向影响,受到固定成本系数和单位回收成本的负向影响;而单位回收收益增加(减少)时,伪装行动力分别受到伪装边际成本和被惩罚后绝对损失额的正向(负向)影响。据此,提出实施废弃食品分类有效回收与良性再利用和强化废弃食品回收处理监管等政策建议。
Aiming at the difference of the unit return revenue because of the size change from the number of informal recyclers in the informal recycling market of waste food,the optimization models of the expected total profit of informal recyclers under the three conditions of constant return,constant increase and decrease are built,the disguise action force and the recovery rate of informal recyclers’ decisions and the effect of the informal recyclers number are analyzed. The numerical analysis was carried out with"zombie meat"as a typical case. The results show that the camouflage action force and the waste food recovery rate of the informal recyclers are positively affected by the quantity of waste food,the probability of camouflage and the sale price of waste food respectively,and are negatively affected by the fixed cost coefficient and the unit recovery cost;when the unit recycling revenue increases(decreases),the camouflage marginal cost and the absolute loss after being punished have the positive effect(the negative effect)on the camouflage action force. Based on this,the policy inspirations are proposed.
