At present, the implementation of developing the system of territorial spatial planning still centers on three types of permits: site selection and pre-examination on the use of land permit, construction land planning permit, and construction project planning permit. As planning permissions involve a wide scope, extend over a long period, and directly affect the vital interests of residents in surrounding areas, the administrative authority must fulfill the requirement of conducting necessary pre-approval public announcement procedures in accordance with relevant regulations. Based on higher-level laws and related policies, various regions have further refined the pre-approval public announcement process, which can be categorized into two types: general public announcement and notification announcement. In the future, national and local legislation on developing the system of territorial spatial planning should further unify key procedural rules, and clarify the specific content of the general public announcement system and notification announcement system for planning permission. so as to promote the realization of procedural justice and substantive fairness in planning permits.
