【摘要】 21世纪以来，中国发生了剧烈的国土空间变化，多层次尺度重组是当前格局的基础。在全球化与逆全球化交织等复杂背景下，理解其尺度重组特征、现象、机制等至关重要。研究通过尺度重组与调节学派理论，基于土地出让数据，结合区位商指数刻画了公共品在国家、区域、地方层级的演变过程。国家层面结果显示，三大城市群逐渐聚焦于公共品投入、中西部地区持续以公共品配置方式形成尺度重组；区域层面根据其发展阶段、组织与跨区交流等呈现出极化到多级化特征；多利益主体参与地方区划调整、新城建设等城市尺度扩张政策，共同形成了空间格局变化的普遍路径。规划调节为尺度重组提供动力源，国土空间规划体系表现了“积累体制”的再中心化，形成了规划制度的尺度上移。不同的规划调节为尺度重组提供动力，使嵌套交叠的多元主体能够持续引入新资本重塑经济社会环境。土地资源的“尺度错配”现象也同步存在于众多地区。严守国土空间规划框架、提升土地资源的配置效率，发挥大城市聚集效应、调动多方积极性将是空间格局优化的重点。更多还原

【Abstract】 Since the 21st century, China has undergone drastic changes in its territorial space, and multi-level re-scaling is the foundation of the current pattern. In the complex context of the interweaving of globalization and deglobalization, it is significant to understand their re-scaling characteristics, phenomena, mechanisms, etc. The study adopts the theory of re-scaling and regulation, based on land transfer data, and combined with the location quotient index to depict the evolution process of public goods at the national, regional, and local levels. At the national level, the results show that urban agglomerations are gradually focusing on public goods investment, and the central and western regions continue to form re-scaling through the allocation of public goods; At the regional level, polarization to multilevel characteristics are presented based on its development stage, organization, and cross regional communication; The participation of multiple stakeholders in local zoning adjustments, new city construction, and other urban scale expansion policies has jointly formed a universal path of spatial pattern changes. This phenomenon indicates that planning regulation provides a driving force for re-scaling, and the national territorial spatial planning system exhibits a decentralization of the "accumulation regime", forming a scale shift in the planning system. At the same time, different planning adjustments provide impetus for re-scaling, enabling nested and overlapping diverse entities to continuously introduce new capital to reshape the economic and social environment. The phenomenon of "scale mismatch" of land resources also exists simultaneously in regions. Therefore, strictly adhering to the national territorial spatial planning framework, improving the efficiency of land resource allocation, leveraging the agglomeration effect of large cities, and mobilizing the enthusiasm of multiple parties will be the focus of optimizing the spatial pattern.更多还原
