制度是碳排放绩效的基本决定因素。然而,知识产权机构对环境的影响,尤其是它对碳排放的影响,很少有人注意。因此,本研究的主要目的是评估知识产权制度对碳减排的影响,揭示了控制碳排放的新解决方案。为了实现目标,本研究将中国国家知识产权示范城市(NIPDC)政策作为知识产权制度建设的准自然实验,利用差异性方法,基于中国城市面板数据,客观评价知识产权制度对碳减排的影响。研讨得出以下重要结论。首先,与非试点城市相比,NIPDC政策使试点城市的城市碳排放量减少了8.64%。特别是,NIPDC政策的“碳减排红利”是长期的,而不是短期的。第二,影响机制分析表明,NIPDC政策可以通过刺激技术创新促进碳减排,尤其是突破性创新。第三,空间溢出分析表明,NIPDC政策可以减轻邻近地区的碳排放,产生明显的空间辐射效应。第四,异质性分析证实,NIPDC政策的碳减排效果在低行政等级城市更为明显,中小城市,西方城市。因此,中国决策者应有序推进国家创新发展计划的建设,加强技术创新,充分发挥NIPDC的空间辐射作用,优化政府作用,从而更好地释放知识产权制度的碳减排效果。
Institutions are the fundamental determinants of carbon emission performance. However, the environmental impact of intellectual property institution, especially its impact on carbon emissions, has been paid little attention. Therefore, the main purpose of this study is to assess the effect of intellectual property institution on carbon emission reduction, revealing a new solution to control carbon emissions. To achieve the goal, this study regards the National Intellectual Property Demonstration City (NIPDC) policy in
China as a quasi-natural experiment of intellectual property institution construction and exploits the difference in difference approach to objectively evaluate the impact of intellectual property institution on carbon emission reduction based on the panel data of
China\'s cities. The study draws the following important conclusions. First, compared with non-pilot cities, the NIPDC policy has reduced urban carbon emissions by 8.64% in pilot cities. In particular, the \"carbon emission reduction dividend\" of the NIPDC policy is in the long term but not in the short term. Second, the influence mechanism analysis shows that the NIPDC policy can promote carbon emission reduction by stimulating technology innovation, especially breakthrough innovation. Third, the space overflow analysis reveals that the NIPDC policy can mitigate carbon emissions in adjacent areas, resulting in obvious spatial radiation effect. Fourth, the heterogeneity analysis confirms that the carbon emission reduction effect of the NIPDC policy is more obvious in low administrative hierarchic cities, small and medium-sized cities, and western cities. As a result, Chinese policymakers should orderly promote the construction of NIPDCs, strengthen technology innovation, give full play to the spatial radiation role of NIPDCs, and optimize the role of government, so as to better release the carbon emission abatement effect of intellectual property institution.
