In the modern context, “fellow countrymen” is closely related to urbanization, reflecting the influence on the “city”. However, in today’s rural revitalization, its role in the “township” is increasingly valued. From the perspective of type research, the “fellow countrymen” can be divided into “aggregation production”, “aggregation consumption”, “decentralization consumption” and “decentralization production”. Different types of “fellow countrymen” have different mechanisms on rural revitalization. The “gathering production” type often promotes rural revitalization through the characteristic industries in real estate and the return of talents. The “gathering consumption” type contributes to the rural areas through returning to their hometown for consumption or donating to their hometown. “Decentralized production” and “decentralized consumption” combine the above two types of functions, and their external development makes the mechanism of rural revitalization similar to that of “agglomeration consumption”. However, their establishment of local brands and development of original industrial forms in their hometown make them similar in mechanism to “agglomeration production”. Therefore, if different types of “fellow villagers” want to give full play to their roles in rural revitalization, the guiding mechanism of the government will be different.
