| 中文摘要 |
| 借助SBM-DEA模型测算了2006～2020年中国277个城市的碳排放绩效水平,利用ArcGIS平台对其演变特征进行了展示,并使用空间杜宾模型实证检验分析了经济转型对碳排放绩效的本地效应和空间溢出效应. 结果表明：①中国城市碳排放绩效水平总体较高但下降趋势明显,且分布呈现出从均衡分布到“U”型转变的低水平集聚的特征；②当前阶段经济转型对碳排放绩效提升的本地促进效应尚未全部显现. 本地城市经济转型的市场化、全球化和财政分权化水平显著提升了本地城市的碳排放绩效,但行政类别分权化水平、环境规制力度和绿色技术创新水平抑制了碳排放绩效的提升；③碳排放绩效具有空间依赖性. 邻近城市经济转型的全球化水平、环境规制力度、绿色技术创新水平和碳排放绩效提高会对本地城市碳排放绩效产生正向溢出效应,而行政类别分权化水平的溢出效应为负. 明晰城市碳排放绩效水平与分布并从经济转型视角进行解释,对促进中国乃至其它国家“双碳”目标的实现均具有重大现实意义. |
| 英文摘要 |
| This study calculates the carbon emission performance of 277 Chinese cities from 2006 to 2020 with the help of an SBM-DEA model, displays its evolution characteristics using the ArcGIS platform, and empirically tests and analyzes the local and spatial spillover effects of economic transformation on carbon emission performance using the spatial Durbin model. The results showed that： ① The carbon emission performance level of Chinese cities was generally high, but the trend of decline was obvious, and the distribution showed the characteristics of low-level agglomeration from equilibrium distribution to U-shaped transformation. ② At the current stage, the local promoting effect of economic transformation on the improvement of carbon emission performance has not been fully revealed. The marketization, globalization, and fiscal decentralization of local urban economic transformation significantly improved the carbon emission performance of local cities, but the decentralization of administrative categories, the intensity of environmental regulation, and the level of green technology innovation inhibited the improvement of carbon emission performance. ③ Carbon emission performance was spatially dependent. The globalization level of economic transformation, environmental regulation intensity, green technology innovation level, and improvement of carbon emission performance of neighboring cities had a positive spillover effect on local carbon emission performance, while the decentralization level of administrative categories had a negative spillover effect. Clarifying the level and distribution of urban carbon emission performance and explaining it from the perspective of economic transformation is of great practical significance for promoting the realization of the "double carbon" goal in China and other countries. |
