The ‘Porter hypothesis’ predicts that well-designed environmental regulations will stimulate businesses to innovate to reduce their environmental impact for efficiency reasons. This article analyses the impacts and anticipation effects of Australia’s carbon price on firms’ carbon reduction activities, through survey data on 466 medium-to-large Australian businesses. We build upon the Porter hypothesis by demonstrating that the anticipated impact of regulation may be as important as its implementation in triggering environmental innovation, thus developing the notion of a ‘signal’ effect.

触发企业对澳大利亚气候政策的回应

“波特假说”预测，精心设计的环境法规将激发企业进行创新，以降低效率对环境的影响。本文通过对466家澳大利亚中型和大型企业的调查数据，分析了澳大利亚碳价对企业减碳活动的影响和预期影响。我们以波特假说为基础，通过证明监管的预期影响可能与实施环境对触发环境创新同样重要，从而发展出“信号”效应的概念。
