摘要
构建了包括生产者和消费者在内的产品生命周期模型.基于社会福利最大化的视角,在一个统一的模型中探讨了最优循环性管制标准和减量化管制标准的确定问题,以及影响最优管制标准的主要因素.研究表明,要素投入的边际产品价值等于其净价格是实现社会福利最大化的条件;而回收再利用成本、要素的边际贡献、物质投入的价格、废弃物的处置费用是影响最优管制标准的重要因素.因此,政策制定者在制定EPR管制标准时,不能片面追求环境绩效还应兼顾经济绩效,以实现社会福利最大化.
From the perspective of social welfare maximization, a product life cycle model involving both producers and consumers was built in which the regulation standards for both recycling and reducing were determined, and the major factors affecting the optimal standards were discussed. The results showed that the socially optimal condition is reached when the value of each marginal product equals its net price, and the recycling cost, input＇ s marginal contribution, price of material input, cost of waste disposal are the most important factors for the optimal standards. Therefore, in order to maximize the social welfare, policy makers should take both environmental and economic performances into account while making EPR （extended producer responsibility） regulation policies.
