存量更新阶段的土地混合利用治理框架OACHSSCD

As urban development shifts from incremental expansion to stock renewal,mixed land use has emerged as a core instrument for alleviating spatial resource con-straints and advancing refined governance.The governance focus has correspondingly evolved from the question of"whether to adopt mixed use"to a systematic demand for"how to achieve effective and adaptive mixed-use outcomes".This paper traces the conceptual evolution of mixed land use from"physical superimposition"and"functional integration"toward"systematic governance",and examines the practical dilemmas inherent to stock renewal contexts,with a attention on the central chal-lenge of"flexible transition and dynamic adjustment".A tripartite"space—rights-governance"framework is developed,delineating the logics of the three dimensions:the space dimension,encompassing land-use allocation,cadastral management,and land value assessment;the rights dimension,encompassing property rights clarifica-tion,interest balancing,and value increment sharing;and the governance dimension,encompassing multi-stakeholder co-governance,cross-departmental coordination,and long-term oversight.The paper further proposes four implementation pathways:regula-tory adaptation and flexible control;property rights coordination and institutional in-novation;benefit balancing and value-sharing mechanisms;and organizational optimi-zation with sustained supervision.This study offers a theoretical framework and prac-tical insights to support the refined governance of mixed land use in the era of stock renewal.
