| 中文摘要:运用我国299个城市的面板数据构建空间杜宾模型，实证研究绿色技术创新对城市碳排放影响的区域差异性和收敛性。结果表明：我国绿色技术创新可以降低碳排放水平，且存在空间关联效应。横向来看，不同区域的绿色技术创新对碳排放的影响具有明显的区域差异性，东部、长三角、珠三角等经济发达地区的影响效应更强，中西部、京津冀等地区相对较弱。纵向来看，2015年以来绿色技术创新对碳排放影响的区域差异持续收敛，根源在于区域经济发展差距的缩小。未来持续推进绿色技术创新、缩小区域发展差距是实现“双碳”目标的必由之路。 |

| Regional Differences and Convergence of Green Technology Innovation on Urban Carbon Emission Reduction—Evidence from Prefecture-level Cities |

| Abstract:The paper uses panel data of 299 China’s cities to construct a spatial Dubin model and empirically studies the regional differences and convergence of the impacts of green technology innovation on urban carbon emissions. The results show that our green technology innovation can reduce carbon emission level, and there is a spatial correlation effect. Horizontally, the impact of green technology innovation on carbon emissions in different regions has obvious regional differences, with the eastern, Yangtze River Delta, Pearl River Delta and other economically developed regions having a stronger impact, while the central and western regions, Beijing, Tianjin, Hebei and other regions being relatively weak. Vertically, regional differences in the impact of green technology innovation on carbon emissions have been converging since 2015, which is due to the narrowing of regional economic development gap. In the future, continuous promotion of green technology innovation and narrowing of regional development gap is the only way to achieve the goals of carbon emission reduction and carbon emission peak . |
