Abstract

In the face of global climate change challenges, China’s implementation of the carbon emission trading (CET) pilot policy has provided new empirical research opportunities. Based on a dataset covering 281 Chinese cities from 2005 to 2021, this paper employs econometric models to conduct an in-depth analysis of the policy’s impact on urban green innovation (UGI). The findings indicate that the CET pilot policy has significantly promoted green innovation activities in affected cities, with positive effects observed both directly in pilot cities and indirectly in non-pilot cities through spatial spillover effects. In addition, the policy has been found to encourage technological investment and enhance public environmental awareness (PEA), further advancing green innovation. The paper also unveils comprehensive policy effects, indicating that the Big Data Comprehensive Test Zone policy and the New Energy Demonstration City policy work synergistically with the CET pilot policy in advancing green innovation. These findings provide valuable experiences and insights for designing environmental policy tools at the national level, promoting green development, and constructing climate change response strategies.

碳排放权交易对城市绿色创新的影响：来自中国碳排放权交易试点政策的经验证据

面对全球气候变化的挑战，中国实施碳排放权交易（CET）试点政策提供了新的实证研究机会。本文基于 2005 年至 2021 年中国 281 个城市的数据集，采用计量经济模型深入分析了该政策对城市绿色创新（UGI）的影响。研究结果表明，CET 试点政策极大地促进了受影响城市的绿色创新活动，不仅在试点城市直接产生了积极影响，还通过空间溢出效应在非试点城市间接产生了积极影响。此外，该政策还鼓励了技术投资，提高了公众环境意识（PEA），进一步推动了绿色创新。本文还揭示了综合政策效应，表明大数据综合试验区政策和新能源示范城市政策与 CET 试点政策在推进绿色创新方面发挥了协同作用。这些发现为设计国家层面的环境政策工具、促进绿色发展和构建气候变化应对战略提供了宝贵的经验和启示。

期刊介绍： Our natural world is experiencing a state of rapid change unprecedented in the presence of humans. The changes affect virtually all physical, chemical and biological systems on Earth. The interaction of these systems leads to tipping points, feedbacks and amplification of effects. In virtually all cases, the causes of environmental change can be traced to human activity through either direct interventions as a consequence of pollution, or through global warming from greenhouse case emissions. Well-formulated and internationally-relevant policies to mitigate the change, or adapt to the consequences, that will ensure our ability to thrive in the coming decades are badly needed. Without proper understanding of the processes involved, and deep understanding of the likely impacts of bad decisions or inaction, the security of food, water and energy is a risk. Left unchecked shortages of these basic commodities will lead to migration, global geopolitical tension and conflict. This represents the major challenge of our time. We are the first generation to appreciate the problem and we will be judged in future by our ability to determine and take the action necessary. Appropriate knowledge of the condition of our natural world, appreciation of the changes occurring, and predictions of how the future will develop are requisite to the definition and implementation of solutions. Frontiers in Environmental Science publishes research at the cutting edge of knowledge of our natural world and its various intersections with society. It bridges between the identification and measurement of change, comprehension of the processes responsible, and the measures needed to reduce their impact. Its aim is to assist the formulation of policies, by offering sound scientific evidence on environmental science, that will lead to a more inhabitable and sustainable world for the generations to come.
