Coordination Degree of Urban Population, Economy, Space, and Environment in Shenyang Since 1990

Abstract

In the background of China's rapid urbanization, the conflicts between urban population, economy, space, and environment are intensified and complicated. This article aims to establish a coordinate assessment method for studying urban population, economy, space, and environment interactions in city scale by principal component analysis and regression analysis. On the basis of the case study on Shenyang city, the results indicated that the integrated development of urban population, economic, and space was in a poor situation from 1993 to 1999, whereas it turned better after 2000, and the urban environment improved steadily after 1998. The static coordination degree of urban integrated development and environment showed obvious periodical and fluctuant characteristics. Compared with the static coordination degree, the dynamic coordination degree appeared to be smooth and lag. The static coordination degree was elementary discoordinative in 1993, 1994, and 1999; whereas it turned to be elementary coordinative between 1995 and 2005. The dynamic coordination degree was elementary discoordinative from 1993 to 1996, whereas it became elementary coordinative overall after 1997.
