摘　　要：文章基于2000~2018年中国285个地级及以上城市绿色专利授权数据,运用Dagum基尼系数、分布动态分析、空间Markov链等方法实证考察中国城市绿色创新水平的空间差异及分布动态。研究结果表明:(1)中国城市绿色创新水平具有较严重的空间非均衡态势,北京、上海、深圳等城市绿色创新水平大幅高于其他城市。(2)随着时间推移,区域间差异对于总体空间差异的贡献逐渐上升,超变密度的贡献逐渐降低。区域间差异的拉大主要表现为高水平城市之间差异扩大,而中等水平与低水平城市之间相对差异缩小。(3)空间效应在中国城市绿色创新发展过程中发挥了显著作用,高水平的空间滞后类型能够显著提高城市绿色创新向更高水平转移的概率,未来中国城市绿色创新的发展存在空间收敛趋向。强化区域间协调、激发协同创新势能成为打破当前中国城市绿色创新严重空间非均衡态势的重要途径。Based on the green patent data of 336 China’s cities from 2000 to 2018, this paper uses Dagum Gini coefficient,distribution dynamic method, and spatial Markov chain analysis to empirically investigate the spatial differences and dynamic evolution of green innovation in China’s cities. The results show firstly that the spatial distribution of green innovation in China’s cities presents a serious non-equilibrium situation;Beijing, Shanghai and Shenzhen have substantially higher levels of green innovation than other cities. Secondly, during the sample period, the contribution of inter-regional differences to the overall spatial difference gradually increases and the contribution of transvariation gradually decreases. The widening of inter-regional differences is mainly manifested in the widening of differences between high-level cities, while the relative differences between medium-level and low-level cities are narrowing. Finally, spatial effects play a significant role in the development of green innovation in China’s cities, and a high level of spatial lag type can significantly increase the probability of transferring urban green innovation to a higher level. The development of green innovation in China’s cities has a spatial convergence trend in the future. Strengthening inter-regional coordination and promoting inter-regional collaboration momentum have become important to breaking the current serious spatial imbalance of green innovation among China’s cities.
