Abstract: Against the backdrop of comprehensive rural revitalization, leisure agriculture has emerged as a pivotal industry form driving rural industrial integration and spatial optimization. However, its compound land demand cannot be fully accommodated by the traditional single-purpose land supply regime. Taking Jiangsu Province as the case study, this paper systematically sorts out the institutional evolution and local practices of leisure agricultural land supply. The findings indicate that Jiangsu's leisure agricultural land supply has generally undergone a transformation from strict land use control to flexible exploration, categorized guarantee and refined governance, forming practical patterns including quota reservation, point-based land supply, flexible land allocation and stock land revitalization. Nevertheless, it still faces dilemmas such as rigid spatial constraints, inadequate planning coordination, unstable policy synergy and weak benefit linkage with local farmers. Accordingly, this paper proposes to advance the collaborative optimization of 'Planning-Governance-Rights Protection' from three dimensions: planning adaptation, policy synergy and rights guarantee, so as to enhance the institutional inclusiveness of the territorial spatial governance system for new rural business forms.
