The diffusion of renewable energy sources is an important policy issue for all countries. In particular, feed-in tariffs (FITs) are a major policy instrument used to diffuse renewable energy sources in developed countries. A few recent studies have found a rebound effect from the installation of solar photovoltaic (PV) systems. However, consumer behavior in relation to electricity consumption following the installation of solar PV systems is largely unknown. In particular, previous studies do not effectively reveal the FIT effect on electricity consumption. Therefore, we set up a model to measure this effect and conduct empirical analysis to confirm the theoretical contribution of the improved model. Our estimation results based on the matching method show that the FIT scheme increases the consumption of electricity purchased from electricity companies if the FIT rate exceeds the electricity price. This finding is important for better understanding the true cost-benefit of FITs.

可再生能源的扩散是所有国家的重要政策问题。特别是上网​​电价补贴（FITs）是用于在发达国家扩散可再生能源的一项主要政策工具。最近的一些研究发现，安装太阳能光伏（PV）系统会产生反弹效应。但是，在安装太阳能光伏系统后，与电力消耗相关的消费者行为在很大程度上尚不清楚。特别是，先前的研究不能有效地揭示FIT对用电量的影响。因此，我们建立了一个测量该效应的模型，并进行了实证分析，以确认改进模型的理论贡献。我们基于匹配方法的估计结果表明，如果FIT费率超过电价，FIT方案会增加从电力公司购买的电力消耗。这一发现对于更好地了解FIT的真正成本效益非常重要。
