Urbanization of Chongqing Municipality: Regional Contributions and Influencing Mechanisms

Enhancing the level and quality of urbanization and embarking on a new path toward the sustainable development of urbanization are the forces that are driving the achievement of stable and healthy economic and social development. Based on data from three population censuses and official statistics spanning from 1997 to 2021, this study decomposed the changes in the urbanization rates in Chongqing during this period. We employed a fixed-effects model to conduct a regression analysis on the factors influencing the regional contributions of urbanization and provide a comprehensive analysis of their mechanisms. The study findings are as follows: 1. The central urban area has been the primary region driving the urbanization in Chongqing since the establishment of the Chongqing municipality; however, since 2017, the new urban area has gradually become the new “main force” driving the urbanization in Chongqing. In different stages, dynamic regions have exhibited a pattern of “diversification—centralization—diversification”. 2. Local urbanization is the main factor promoting the urbanization development in Chongqing, whereas remote urbanization has only played a supplementary role. The overall urbanization pattern in Chongqing is characterized by “local urbanization and population inflow”. The central urban area has primarily propelled the urbanization of Chongqing through remote urbanization, whereas the new urban area, as well as the northeastern Chongqing area and southeastern Chongqing area, have predominantly driven the urbanization of Chongqing through local urbanization. In the four major regions and 38 counties, the predominant urbanization type was often “local urbanization and population outflow”. 3. The level of the contribution of different regions to the urbanization development in Chongqing is the combined result of factors such as economic development, local administrative capacity, improvement in public services, and enhancement in transportation infrastructure.
