通过建立垄断企业先选择R&D投入再选择能源数量的两阶段模型，比较了上网电价和可再生能源组合标准两种规制政策的不同效果。结果表明，FIT比RPS更有效地增加可再生能源的数量（装机容量），并刺激R&D投入，以降低成本。而RPS政策在减少碳排放和提高消费者剩余方面更有效。除了现有的研究结果外，我们无法对这两项政策的社会福利效果得出准确的结论。两种政策对社会福利的影响在很大程度上取决于负外部性的水平。
By establishing a two-stage model in which a monopolization firm first chooses R&D input and then the quantity of energy, this paper compares the different effects of two regulatory policies: feed-in tariff (FIT) and renewable portfolio standard (PRS). The results show that FIT is more efficient than RPS to increase the quantity of renewable energy (installed capacity) and to stimulate the R&D input to reduce costs. And RPS policy is more efficient to reduce the carbon emissions and to improve the consumer surplus. Apart from existing findings, we cannot obtain the accurate conclusion about the effects of social welfare under the two policies. The effects of two policies on the social welfare heavily depend on the level of negative externality.
