摘　　要：作为应对全球气候变化的重要杠杆,碳排放权交易政策不仅有力推动了减排目标的达成与低碳经济的蓬勃发展,而且在引领城市迈向绿色创新之路上发挥着关键作用。基于2006—2021年城市层面绿色专利数据构建双重差分模型,实证检验碳排放权交易政策对城市绿色创新的激励作用以及区域异质性、政策机制异质性在其中的影响。研究结果显示,碳排放权交易政策对城市绿色创新有显著的促进作用,特别是在策略性创新领域。碳排放权交易政策在东部地区的实施效果优于中、西部地区,在非资源型城市的实施效果优于资源型城市,其中在Ⅱ型大城市效果最强。此外,政策机制设计也会对其实施效果产生重要影响,研究表明,有偿配发和高交易价格更能激励绿色创新。因此,为推动城市绿色创新和经济可持续发展,应加强绿色创新审查与补贴,优化碳排放交易政策,制定试点城市差异化策略,推行有偿配发模式,并建立健全严格的监管体系,加强碳排放权交易市场的透明度和信息披露。As an important lever in addressing global climate change,carbon emission trading policies have not only significantly facilitated the achievement of emission reduction targets and the vigorous development of a low-carbon economy,but also played a crucial role in leading cities towards the path of green innovation.This study employs a difference-in-difference model based on green patent data at the city level from 2006 to 2021,to empirically examine the impact of the policy on urban green innovation and the influence of the heterogeneity in terms of the region and policy mechanism.Findings reveal a significant boost in urban green innovation,particularly in strategic innovations,under the carbon trading regime.The policy exhibits stronger effects in eastern regions compared to central and western areas,and non-resource-dependent cities outperform those reliant on resources,with II-type megacities experiencing the most pronounced effects.Furthermore,policy design factors matter.Results indicate that compensated allocation and higher transaction prices enhance green innovation incentives.Therefore,to propel urban green technological advancements and sustainable economic growth,governments should enhance green innovation assessments and subsidies,refine carbon trading policies,implement differential strategies for pilot cities,promote a fee-based distribution system,and establish robust regulatory frameworks,ensuring transparency and adequate information disclosure in the carbon market.
