Considering that Canada joined and then withdrew from the Kyoto Protocol, we assess the impact of the dynamics of Canada's environmental policy on the general innovation and environmental innovation of oil and gas firms. This study compensates for the shortcomings of the Porter hypothesis, which features no discussion of the influence of a loosened environmental policy on innovation. We highlight that the quantity and quality of innovation can be measured using the numbers of patents and citations of patents as proxy variables. We find that the dynamics of Canada's environmental policy have an asymmetric impact on oil and gas firms' innovation; strict policy promotes firm innovation and loose regulation reduces firm innovation, with the positive effect of strict policy being stronger than the negative effect of loose policy. In addition, environmental policy has a strong impact on environmental innovation. A loosened environmental policy increases the number of environmental patents but reduces the number of citations of environmental patents.
考虑到加拿大加入并随后退出了《京都议定书》，我们评估了加拿大环境政策的动态对石油和天然气公司总体创新和环境创新的影响。本研究弥补了波特假说的不足，该假说没有讨论放松的环境政策对创新的影响。我们强调，可以使用专利数量和专利引用数量作为代理变量来衡量创新的数量和质量。我们发现，加拿大环境政策的动态对石油和天然气公司的创新有不对称的影响；严格的政策促进了企业创新，宽松的监管减少了企业创新，严格政策的积极影响强于宽松政策的消极影响。此外，环境政策对环境创新有很强的影响。宽松的环境政策增加了环境专利的数量，但减少了环境专利的引用数量。
