摘要

城市绿色创新（UGI）对于环境保护、生态保护和高质量的经济增长至关重要。本研究利用绿色专利评估了中国 287 个地级及以上城市的城市绿色创新水平。然后，利用达古姆基尼系数、核密度估计（KDE）和收敛模型，研究了中国各地 UGI 的地区差异、分布动态和收敛情况。研究结果如下(1）总体而言，城市居民人均可支配收入的地区差异趋于缩小，而造成这种差异的主要因素是经济区之间的差异。(2) KDE 显示，UGI 水平呈上升趋势，各经济区内部呈现两极分化。(3) 除东北经济区和黄河中游经济区外，其他经济区的全国 UGI 呈现出明显的 σ 趋同，而各经济区则呈现出绝对和有条件的 β 趋同。

China’s urban green innovation: Regional differences, distribution dynamics, and convergence

Urban green innovation (UGI) is essential to environmental protection, ecological conservation, and high-quality economic growth. Using green patents, our study assessed the level of UGI of 287 Chinese cities at and above the prefecture level. Then, using the Dagum Gini coefficient, kernel density estimation (KDE), and convergence models, we examined regional differences, distribution dynamics, and convergence of UGI across China. The study’s findings are as follows: (1) Overall, regional differences in UGI tended to narrow, and the main contributor to these differences was the difference between economic zones. (2) KDE showed that the level of UGI was rising, which was polarized within each economic zone. (3) The national UGI in economic zones other than the Northeast and Middle Yellow River Economic Zones featured significant $σ$ convergence, while each economic zone showed absolute and conditional $β$ convergence.

期刊介绍： The Chinese Journal of Population, Resources and Environment (CJPRE) is a peer-reviewed international academic journal that publishes original research in the fields of economic, population, resource, and environment studies as they relate to sustainable development. The journal aims to address and evaluate theoretical frameworks, capability building initiatives, strategic goals, ethical values, empirical research, methodologies, and techniques in the field. CJPRE began publication in 1992 and is sponsored by the Chinese Society for Sustainable Development (CSSD), the Research Center for Sustainable Development of Shandong Province, the Administrative Center for China's Agenda 21 (ACCA21), and Shandong Normal University. The Chinese title of the journal was inscribed by the former Chinese leader, Mr. Deng Xiaoping. Initially focused on China's advances in sustainable development, CJPRE now also highlights global developments from both developed and developing countries.
