摘要

本文评估了日本地方政府资本投资补贴对屋顶太阳能光伏系统安装和价格的影响。通过创建涵盖2009年至2014年期间的微观层面独特面板数据集，我们比较了采用补贴的市政当局与未采用补贴的市政当局，以分析其对安装量和系统价格的影响。研究结果表明，尽管城市补贴的效果取决于收入等几个条件，但城市补贴显著地诱导了屋顶光伏的安装。另一方面，我们发现没有证据表明，在补贴较高的城市，屋顶光伏系统价格下降有影响。补贴似乎反而起到了提高价格的作用。

Effects of local government subsidy on rooftop solar PV in Japan

This paper evaluates the impact of local government capital investment subsidies for the installation and the price of rooftop solar photovoltaic (PV) system in Japan. By creating the micro-level unique panel dataset covering the period between 2009 and 2014, we compared municipalities that employed subsidies with municipalities that did not to analyze their effects on the amount of installation and the system prices. Our results indicated that the municipal subsidies significantly induced the installation of rooftop PV although their effects depended on the several conditions such as income. On the other hand, we found no evidence of an effect on rooftop PV's system price reduction in municipalities with higher exposure to the subsidies. Subsidies rather seemed to have an effect to raise prices up.
