摘要｜Abstract
本文分析了中央、地方政策交互对弱化环境外部性的影响。首先，我们设定了一个理论模型，分析这种政策交叠对地方环境执法力度与企业排放的影响。其次，我们使用了瑞典数据对模型进行检验。分析结果表明，地方环境规制者制定的污染排放强度不会强于国家标准。大部分的污染减排得益于国家层面环境规制，而地方规制的作用并不明显。
In this paper, we analyze the effects of the interaction between national and local policies designed to reduce an environmental externality that causes environmental damages both nationally and locally. We formulate a theoretical model to develop hypotheses regarding the combined effects of such policies on the stringency of the local policies and on firms' emissions reductions. To test our hypotheses, we use actual data for Sweden, where emissions of nitrogen oxides from combustion plants are subject to a heavy national tax and to individual emissions standards set by county authorities. Our analytical findings suggest that it is unlikely that local regulators will impose emissions standards stringent enough to achieve further reductions than those induced by the national tax. This is confirmed in our data, where most emissions reductions can be attributed to the national tax and the effects of the emissions standards are not significant.
