【摘要】 欠发达地区是中国推进高质量发展的重点难点区域，该类地区高质量发展既要立足区情走因地制宜的差异化发展道路，又要把握数字化带来的机遇实现跨越式追赶。本文借鉴空间经济学经典模型，在识别欠发达地区经济地理特征基础上，阐释了数字化赋能欠发达地区高质量发展的机理，并以武陵山区为例探讨了欠发达地区高质量发展路径。主要发现：(1)“远距离、高分割、低密度、高异质”等经济地理特征制约了欠发达地区的高质量发展；(2)数字化通过缩减距离、消除分割、提升密度和放大异质性重塑经济地理格局，并借助创新驱动、协调引领、绿色转型、开放发展、共享包容等举措，重组生产要素、升级产业体系、优化空间格局与和谐人地关系促进欠发达地区高质量发展；(3)武陵山区高质量发展的关键在于克服远距离制约推进融通性发展、突破低密度制约推进集聚性发展、消除高分割制约推进协同性发展、避免同质化竞争推进差异性发展、加快数字化赋能推进融合性发展。更多还原

【Abstract】 Underdeveloped regions represent critical and challenging areas for China’s pursuit of high-quality development. Achieving high-quality development in these regions necessitates not only a differentiated development approach rooted in local conditions but also the strategic embrace of opportunities presented by digitalization to foster leapfrog advancement. This paper applies classic models of spatial economics to identify the economic and geographical characteristics of underdeveloped regions, elucidating the mechanism through which digitalization empowers their high-quality development. Focusing on the Wuling Mountain Area as a case study, we explore nuanced development pathways for such regions. Our key findings include:(1) Economic geographical features such as "long distances, high fragmentation, low density, and high heterogeneity" significantly impede the high-quality development of underdeveloped regions.(2) Digitalization and intelligent technologies are instrumental in reshaping economic geographical patterns by mitigating distance, overcoming fragmentation, enhancing density, and amplifying heterogeneity. This transformation, coupled with strategies centered on innovation-driven growth, coordinated leadership, green transformation, open development, and inclusive sharing, facilitates the reorganization of production factors, the upgrading of industrial systems, the optimization of spatial layouts, and the harmonization of human-land relationships, thereby propelling high-quality development in underdeveloped regions.(3) For the Wuling Mountain Area, the pivot to high-quality development hinges on overcoming long-distance constraints to foster integrated development, breaking through low-density limitations to promote agglomerated development, eliminating high-fragmentation barriers to achieve coordinated development, averting homogeneous competition to ensure differentiated growth, and accelerating digital empowerment to drive integrated progress.更多还原
