摘　　要：伴随着先行先试改革创新经验的复制推广与制度型开放内涵的不断深化,探索绿色低碳模式上升为国家推动自由贸易试验区高质量发展的一项重要举措.聚焦自由贸易试验区制度创新核心任务,测度量化了各片区绿色投资自由化和绿色贸易便利化水平,运用组群-时期平均处理效应估计法(CATT)、插补法(imputation)和堆叠法(stacked DID)等前沿方法探究了自由贸易试验区的碳排放双控效应.结果表明:①自由贸易试验区的分批次设立使碳排放总量下降27.40%,碳排放强度下降14.30%.②自由贸易试验区通过外资进入的绿色创新溢出效应、本土企业的绿色创新直接效应和数字贸易的绿色创新间接效应实现碳排放双控.③市场准入负面清单的全面实施、我国与其他国家签订实施自由贸易协定和国际绿色贸易壁垒的增大,均对自由贸易试验区的碳排放双控产生了显著的正向调节效应.④自由贸易试验区的碳排放双控效应存在显著的空间溢出特征,在其周边550 km的半径表现出最大效能,使周边城市碳排放总量下降18.30%,碳排放强度下降10.10%.⑤异质性分析表明,制度创新水平和政府职能转变程度较高地区比较低地区的碳排放总量控制效果分别高出13.10%和13.70%,碳排放强度控制效果分别高出8.40%和3.40%“;一带一路”沿线城市碳排放总量控制效果比非沿线城市高出9.60%,碳排放强度高出8.80%;开通中欧班列的城市碳排放总量控制效果比未开通城市高出16.80%,碳排放强度高出7.50%.在对接国际经贸规则和实现高质量发展方面,自由贸易试验区须重点关注新注册登记外资企业进入的绿色低碳资质审查和突破绿色贸易技术性壁垒的先行先试,以高水平开放协同助力我国碳排放双控进程.With the replication and promotion of the experience of pilot reform and innovation,as well as the continuous deepening of institutional openness,exploring green and lowcarbon models has become an important measure for the country to promote the high-quality development of free trade pilot zones.This study focused on the core task of institutional innovation in free trade pilot zones,measured and quantified the level of green investment liberalization and green trade facilitation in each region,and explored the carbon emission dual control effect of free trade pilot zones using cutting-edge methods,such as group period average processing effect estimation(CATT),imputation,and stacked DID.The research conclusions were as follows:①The phased establishment of free trade pilot zones reduced the total carbon emissions by 27.40%and the carbon emission intensity by 14.30%.②The pilot free trade zone achieved dual carbon emission control through the spillover effect of green innovation from foreign investment,the direct effect of green innovation from local enterprises,and the indirect effect of green innovation from digital trade.The comprehensive implementation of the negative list of market access,the signing and implementation of free trade agreements between China and other countries,and the increase of international green trade barriers have all had a significant positive regulatory effect on the dual control of carbon emissions in free trade pilot zones.The dual control effect of carbon emissions in the free trade pilot zone exhibited significant spatial spillover characteristics,showing maximum efficiency within a radius of 550 km,resulting in a reduction of 18.30%in the total carbon emissions of surrounding cities and a decrease of 10.10%in carbon emission intensity.Heterogeneity analysis showed that regions with higher levels of institutional innovation and government function transformation had a 13.10%and 13.70%higher total carbon emission control effect compared to that of regions with lower levels and a
