Using geometric methods, this study constructed a space-time path method to characterize the space-time relationship between municipal district adjustment and built-up area expansion, and drew the space-time path sets of major prefecture level cities from 2000 to 2010 by constructing a coordinate system of the standardized built-up areas and municipal district areas. This divided them into four quadrants, namely, H-H, L-H, L-L, and H-L, based on the relative mean value to evaluate overall and individual stability by three indexes of the trajectory vectors, namely, direction, length, and slope. Results provide the following conclusions. 1) Municipal district adjustment is an effective spatial expansion way for city-scale promotion in China. Since 2000, municipal district adjustments have been mainly distributed in the eastern coastal regions and mid-western capital cities along with their surrounding cities. 2) Municipal district adjustment affects the scale and status of a city in China. Many cities that have expanded municipal districts behave stably and cross quadrants. 3) Great majority second-tier cities have effectively promoted their scale and status through municipal district adjustment. The municipal district adjustment of medium and small cities in the mid-west area is relatively advanced compared with city development. 4) Municipal district adjustment with minimal magnitude is severely restricted from upgrading the scale and status of a city. The transformation from entirely incorporated counties or cities to municipal districts should be the mainstream in future municipal district adjustment.展开更多

It has become an integral part of the transformation of China's urban and regional governance. Based on an analysis of ADA cases at the metropolitan level since 1997, this paper suggests that the stages and characteristics of ADA in China are closely related to the metropolitanization process. The internal dynamics and external constraints jointly created two stages of ADA at the metropolitan level in China, namely, a first stage from 1997 to 2007 and a second stage from 2008 to now. In the first stage, ADA primarily aimed at turning counties into districts, to meet the metropolis' demands for expansion. In the second stage, local governments laid equal stress on the two approaches of ADA, i.e., turning counties into districts and district restructuring. Such a change corresponded to the diversification of development demands of the metropolitan area. The evolution of ADA from the first stage to the second not only reflects the changing characteristics of metropolitanization at different times, but also demonstrates the viability of ADA as a means to improve the governance structure of the metropolitan area. ADA at the metropolitan level in China since 1997 basically accommodates the development of space and governance in the metropolitan area, which promotes the rapid development of a large metropolitan area.展开更多
