From Non-Fossil Fuel Obligation (NFFO) implemented in 1990s to Renewable Obligation (RO) started from 2002, the UK government aimed to promote long-term development of renewable energy. However, due to complexity of the policy, market uncertainty, and speculation in green certificates market, it is impossible for RO to drive huge amount investment towards large-scale renewable energy development. As a result, the UK government announced to start the Electric Market Reform and transitioned to Feed-in-Tariff. This paper introduces the evolvement of the RO policy, analyzes its mechanism and impacts, and explains the new policy portfolio. It also raises key comments and suggestions for establishing Chinese RPS.%从90年代的非化石燃料义务政策到2002年以来的可再生能源义务政策,英国一直致力于通过市场配额机制推动可再生能源发展.但由于政策机制设计复杂,不确定性较大,以及罚金返还导致的市场投机等问题,无法拉动足够投资保障可再生能源快速发展.2011年,结合碳减排目标,英国政府计划推出一揽子电力市场改革方案(EMR),其重点之一是可再生能源义务逐步向差价合约固定电价政策转移.本文通过综述英国可再生能源义务政策演变历程,解析评价可再生能源证书市场运行机制和实施效果,并介绍英国电力市场改革方向,以及对我国的启示.
