This paper provides measurement of relative public environmental policy efficiency (EPE) at country level. We use data envelopment analysis methods to construct measures of relative efficiency, for 39 countries over the period 1995–2010. Then, we estimate a truncated regression model, using the bootstrap method of Simar and Wilson (J Econom 136(1):31–64, 2007) in order to determine the factors that affect EPE. Our findings indicate that (i) EPE is affected both by economic and political variables, (ii) the effect of the political regime on EPE depends on the level of economic development. Our results are robust across alternative specifications.

环境政策效率：度量和决定因素

本文提供了国家一级相对公共环境政策效率（EPE）的度量。我们使用数据包络分析方法来构建1995-2010年期间39个国家/地区相对效率的度量。然后，我们使用Simar和Wilson的引导方法（J Econom 136（1）：31–64，2007）估计一个截短的回归模型，以确定影响EPE的因素。我们的发现表明：（i）EPE受经济和政治因素的影响，（ii）政治体制对EPE的影响取决于经济发展水平。我们的结果在其他规范中都很可靠。
