根据环境库兹涅茨曲线（EKC）假说，经济增长和减少环境退化是相容的目标。经济绩效与环境污染之间的倒U型关系表明，从经验上讲，在达到某个临界收入点后，一个经济体的污染水平就会降低。对EKC的经验证据的一个可能的解释是污染减排的收益增加，其中减排效率随着减排规模的增加而增加。加倍的清理工作可以使减少污染的效果加倍。由于效率的提高降低了减排的成本，污染可能会随着减排的增加而减少。这项研究检验了减少污染的回报递增的假设。自1970年以来，美国农业部门环境风险的经验证据支持收益递增的存在。此外，我估计污染治理的生产率，使用改进的经验生产率测量方法和明确控制的技术水平。结果表明，包括环境生产力变量的EKC框架的重要性。(c)2005 Elsevier B.V.保留所有权利。
According to the Environmental Kuznets Curve (EKC) hypothesis, economic growth and the reduction of environmental degradation are compatible goals. An inverted U-shaped relationship between economic performance and environmental pollution suggests that, empirically, an economy is associated with smaller levels of pollution after some threshold income point. One potential explanation for the empirical evidence of an EKC is increasing returns to pollution abatement, where the abatement efficiency rises with an increase in the scale of abatement. Doubling the clean-up efforts more than doubles the abatement of pollution. As this efficiency gain makes abatement less expensive, pollution might fall as more abatement is undertaken. This study tests the hypothesis that there are increasing returns to abating pollution. Empirical evidence on environmental risks in the US agricultural sector since 1970 support the existence of increasing returns. In addition, I estimate the productivity of pollution abatement using refined empirical productivity measurement methods and explicitly control the level of technology. The results show the importance of including an environmental productivity variable in the EKC framework. (c) 2005 Elsevier B.V. All rights reserved.
