摘　　要：区域协调发展需要在区域协同的基础上实现人均意义上的区域经济持续增长和平衡发展。数字经济时代,数字知识已成为技术进步和经济增长的源泉,是促进区域协调发展的重要力量。本文基于大语言模型方法和专利引用信息测度了数字知识的跨区域流动,进一步结合夜间灯光和人口栅格数据,深入考察了数字知识流动对区域协调发展的影响,赋予传统增长理论数字时代的新内涵。研究发现,由发达地区流入欠发达地区的数字知识能够促进区域协调发展。机制分析表明,在欠发达地区产业与数字知识适配的前提下,改善供给侧对需求的适配性以缓解要素禀赋差距,是数字知识流动促进区域协调发展的关键路径。异质性分析表明,东部发达城市向中西部欠发达城市的数字知识流动、大型发达城市向小型欠发达城市的数字知识流动,以及发展水平相近城市间的数字知识流动促进区域协调发展的效果更好。拓展分析发现,城市内部中心区县流向外围区县的数字知识能够显著缓解“中心—外围”格局,并且数字知识流动促进区域协调发展的作用是长期存续的。因此,政府应通过优化区域数字产业结构、建立灵活的需求反馈机制等方式,有针对性、有优先级地促进数字知识的跨区域流动,发挥长期积极效应。Regional coordinated development is necessary for China to achieve high-quality economic growth,requiring sustained economic growth and balanced development on a per capita basis.As a key element of the era of the digital economy,digital knowledge flows may significantly impact regional coordinated development.This study focuses on the relationship between digital knowledge flows and regional coordinated development,aiming to provide policy guidance for balancing equity and efficiency in the era of the digital economy.Using patent text data from the China National Intellectual Property Administration,this study employs a large language model to identify digital technologies covered in patents.Digital knowledge flows are then characterized based on patent citations.The findings indicate that digital knowledge inflows from developed to less developed regions contribute to regional coordinated development.Mechanism analysis reveals that under the premise of industry compatibility to digital knowledge in less developed regions,enhancing supply-side compatibility to demand to mitigate the gap in factor endowments is a key pathway for digital knowledge flows to promote regional coordinated development.Heterogeneity analysis shows that digital knowledge flowing from developed cities in the eastern region to less developed cities in central and western regions,from large developed cities to small less developed cities,and between cities with similar development levels has a more significant impact on regional coordinated development.Extended analysis shows that within cities,digital knowledge flowing from central districts to peripheral districts significantly enhances intra-city coordinated development.Moreover,the positive effect of digital knowledge flows on regional coordinated development is sustained in the long run.This study carries significant policy implications.The findings suggest that the government should strategically and selectively promote cross-regional flows of digital knowledge by optimizing regional
