Spatial–temporal changes of rurality driven by urbanization and industrialization: A case study of the Three Gorges Reservoir Area in Chongqing, China

China is transitioning from a traditional agrarian society into a modern industrial urban society. The main objective of this study is to establish a simple index to characterize the integrated transformation in a fixed area during China's process of urbanization and industrialization. This research focuses on key aspects of the urban rural integration that is occurring land usage, production efficiencies, employment, and household registration structures to establish a "Relative Rurality Index" (RRI). It assesses these measures in the Three Gorges Reservoir Area of Chongqing (TGRAC). This index is not used to identify absolute urban or rural zones spatially, but to represent the gradients between the min a fixed area. RRI evaluations conducted in 2000 and 2010 indicate that a decade of development has led to an across-the-board decline in rurality in all TGRAC counties. Imbalances in area developments have also increased, with a clear rurality spatial differential, and basic correspondence between the spatial distribution of rurality and the urbanization of strategic deployments. Policy and non-Linear regression analyses show that changes in the rurality of the TGRAC are consistent with the derivative of the central government's strategic programs and policies. In short, the urban rural system in the TGRAC has undergone deep and lasting change. The results of this study show that the rurality characterized by RRI is both more accurate and comprehensive than the urbanization level presented in government statistics. Based on an in-depth analysis of the urban rural systems, this study provides an effective framework for policy-making that will support healthy urbanization and industrialization in China.
