| 中文摘要 |
| 科学理解数字生态文明建设水平、时空格局和作用机制，对新发展格局下国家加快建设绿色智慧的数字生态文明具有重要意义. 基于2011~2022年282个地级市面板数据，采用Dagum基尼系数、高斯核密度估计、俱乐部收敛检验和二次指派程序，分析数字生态文明建设水平、时空格局及作用机制. 结果表明：①中国数字生态文明建设水平综合指数及其子系统指数虽不够高，但均呈现稳步上升态势；②全国及八大综合经济区数字生态文明建设水平存在明显的地区差异，且差异主要来源于超变密度，地区间差异的作用次之，地区内差异的影响最小；③数字生态文明建设的地区内差距在不断扩大，除东北地区外，全国及其他地区均存在极化现象；④城市数字生态文明建设的不平衡局面尚未得到根本扭转，且城市间存在显著空间分化，全国及八大综合经济区均已形成以高水平俱乐部为引领、其他城市持续追赶的梯度发展格局；⑤缩小数字生态文明建设成效差异是推进数字生态文明建设协调发展的根本动力，且提升城镇发展的空间协调性和加强差异化金融服务对缩小数字生态文明建设区域差异具有显著的积极作用. 研究为有效推进数字生态文明建设提供了重要启示，国家应充分发挥高水平地区的示范引领作用，引导各地区结合自身特点探索差异化数字生态文明建设路径，并针对不同区域的发展阶段实施梯度化政策支持. |

| Scientific understanding of the construction level， spatial and temporal patterns， and mechanisms of digital ecological civilization is of great significance for the country to accelerate the construction of a green and intelligent digital ecological civilization （DEC） under the new development pattern. This study， based on panel data from 282 prefecture-level cities in China from 2011 to 2022， employed the Dagum Gini Coefficient， Gaussian kernel density estimation， club convergence test， and the quadratic assignment procedure to analyze the construction level， spatio-temporal pattern， and mechanisms of DEC. The findings reveal： ① Although the comprehensive index of China's DEC construction level and its subsystem indices remained relatively low， they showed a steady upward trend. ② Significant regional differences existed in the construction level of DEC across the nation and within the eight major economic zones. The main source of differences was hyper-variation density， with inter-regional differences playing a secondary role， and intra-regional differences having the minimal effect. ③ While maintaining certain commonalities， the national and eight economic zones' kernel density distribution curves also exhibited obvious regionally differentiated characteristics. During the sample period， the level of DEC construction nationwide and across regions exhibited an upward trend， with widening regional gaps. Except for in the northwest region， polarization phenomena existed nationwide and in other regions. ④ Urban DEC construction remained imbalanced， and cities showed significant spatial differentiation. Across the nation and within the eight major economic zones， high-level city clusters led a gradient development pattern， and other cities continually caught up. ⑤ The basic conditions， construction support， and construction effectiveness of DEC all had significant positive impacts on differences in digital ecological civilization construction， with construction effectiveness having the largest impact coefficient， making it the primary source of differences. Additionally， enhancing the spatial coordination in urban development and st rengthening differentiated financial services helped narrow regional differences in digital ecological civilization construction. Notably， various driving factors exhibited significant heterogeneity across different comprehensive economic zones. This study provides important insights for effectively advancing DEC construction. The government should fully leverage the demonstrative and leading role of high-performing regions， guide different regions to explore differentiated paths for DEC construction based on their unique characteristics， and implement gradient-based policy support according to the development stages of different regions. |
