Interaction Relationship Between Built-Up Land Expansion and Demographic-Social-Economic Urbanization in Shanghai-Hangzhou Bay Metropolitan Region of Eastern China

摘要

Employing coupling coordination degree model (CCDM), this research attempts to reveal the interaction relationships between built-up land expansion (BLE) and demographic-social-economic (DSE) urbanization in Shanghai-Hang-zhou Bay (SHB) Metropolitan Region. It first compared the development trends of four elements, including built-up land expansion level, demographic urbanization, social urbanization, and economic urbanization from 1994 to 2015 through descriptive statistics. Then CCDM was used to identify the spiral escalation trend relationships between built-up land expansion and demographic/social/economic urbanization, respectively. The findings revealed that the degree of coupling coordination between BLE and DSE urbanization had the trend to ascend in SHB, and Shanghai has a more superior balanced development tendency than other cities. It concludes that CCDM can be implemented as an effective approach to evaluate the coupling relationship, and the related agencies in SHB can strengthen the coordination to provide suggestions and make decisions for the coordinated development of urban agglomeration.
