Abstract: The inherent characteristics of small scale, scattered distribution and many governance subjects in China's rural areas lead to numerous obstacles to rural revitalization. To this end, the research introduces the development concept of 'unitary', forms a regional community with unified goals by integrating individuals with similar geographical proximity and attributes, and makes overall allocation of resource elements in a larger spatial scope, thereby enhancing the adaptability of planning and governance. Firstly, the logical basis and identification method for rural revitalization unit construction are clarified, and the empirical research based on rural revitalization unit is put forward by taking Dongguang County as an example. The results identify five kinds of units: ecological oriented type, agricultural oriented type, industrial oriented type, comprehensive developing type, and potential promoting type. According to the characteristics and typical problems of each type, the research constructs a systematic construction framwork centered on county-level rural revitalization unit, and proposes the suitable planning pathway for various types of rural revitalization. Finally, this research suggests the mechanisms of planning transmission, interest coordination and governance consultation should be constructed.
