我们研究了在瑞典受到非常强有力的政策监管的大型固定污染源减少NOx的情况下，技术变化的实际过程。在降低总排放量方面已经取得了相当大的进展，本文试图对行业的平均改进进行分类，以研究其中有多少是由于先行者的创新，有多少是通过采用和传播技术实现的。我们发现这两个因素都非常重要。创新一直很迅速：最好的公司已经减少了约70%的排放量。尽管如此，大多数公司的裁员实际上甚至更快，因此中等规模的公司已经赶上了最佳实践。我们分析了所观察到的技术变化的各种特征。
We study the actual process of technical change in the case of NOx abatement from large stationary sources that have been regulated by very forceful policies in Sweden. Considerable progress has been made in lowering aggregate emissions and this paper seeks to disaggregate average industry improvements to study how much of it is due to innovations by first movers, and how much is achieved by adoption and diffusion of technology. We find both factors very important. Innovation has been rapid: the best firms have cut emissions on the order of 70%. In spite of this, reductions have actually been even more rapid for the majority of firms so that the median firms have caught up with best practice. We analyze various characteristics of the technological change observed.
