Abstract：The rural construc.on planning permit system has played an important role in regula.ng rural construc.on ac.vi.es. However, issues such as illegal construc.on, land encroachment, and ecosystem damage remain frequent in prac.ce. Using content analysis and focusing on key policy texts since the reform and opening up, this paper, based on the framework of the discon.nuous equilibrium theory, reviews the policy evolu.on of the rural construc.on planning permit system. It iden.fies that under the interac.on between the policy landscape and policy field, the system has evolved from simplified management to standardized management, and further to comprehensive spa.al control. The administra.ve and execu.on mechanism reforms around the concept of “integra.on of mul.ple plans” have temporarily alleviated contradic.ons between planning management, but have failed to fundamentally address the problem of “divided governance” in spa.al management systems. The execu.on issues of the rural construc.on planning permit system are the result of the complex and systema.c interplay between ins.tu.onal and mechanism factors in spa.al governance. The paper proposes future op.miza.on direc.ons, including enhancing the central-local management system, op.mizing interdepartmental collabora.on mechanisms, establishing a full life-cycle land use control system, and strengthening the poli.cal and legal nature of the planning permit system.
