摘要

本文建立了兩期模型，探討回收政策和押金返還政策對環境損害造成的影響。在回收政策下，我們找出最適的回收率及回收再利用率，並探討獨佔廠商如何利用回收再製和新的原料投入，在最終財市場得到最適的跨期利潤。同時，我們也找出對環境損害最小的最適回收率和回收再利用率。在押金返還政策下，我們利用廠商生產最終財所需支付的的押金來補貼回收再製的生產。同時，也找出了極小化環境損害的最適押金和補貼。最後，將兩個政策對環境損害的影響程度做比較，並發現產品品質和新的原料投入會影響最適的環境政策。

The thesis builds a two-period model to examine the impact of take-back (TB) and deposit-refund (DR) policies on environmental damage. In the TB regime, we explore the optimal recovery and recycling policies. We investigate how a monopolist in a final good market uses recycled and primary inputs to optimize its intertemporal profits. We also derive the optimal recovery and recycling policies which minimize the environmental damage. In the DR regime, we impose a deposit on the final good production and use the funds collected to subsidize the recycling activities. We derive the optimal deposit and subsidy (refund) policies which minimize the environmental damage. Finally, we compare the difference of environmental damage between TB and DR measures. We also explore how the product quality and the price of primary input affect the optimal environmental policies.
