The local and nearby urbanization in the new era is an important content and manifestation of the new urbanization, and its industrial cultivation has played a driving role in accelerating the new urbanization process.Based on the "sub-core" theory, the logical relationship between the industrial cultivation of local and nearby urbanization in the new era and "sub-core" theory was analyzed in the paper. It was believed that the industrial cultivation of local and nearby urbanization in the new era provided the driving force for the "sub-core" construction of country economy, and the formation of "sub-core" of country economy provided a spatial platform for the industrial cultivation of local and nearby urbanization in the new era, and the two were closely related. On this basis, the formation mechanism and realization path for the industrial cultivation of local and nearby urbanization in the new era were analyzed specifically, aiming at providing reference for the industrial cultivation of local and nearby urbanization in the new era.
