Abstract:

Our study aims at assessment of sustainable development of 30 municipalities and provincial capitals in China. First, we designed an assessment indicator system, which is composed of economic, social, and environmental subsystems. Secondly, we used the entropy method to calculate each indicator's weight and then applied grey relational analysis to evaluate sustainable development capacities of these cities. The results show that, although cities in the east generally have greater sustainable development capacities, the developments among the three subsystems are uneven. Some cities in central and western China are well-developed in terms of their economic and social systems. However, the pollutant emission intensities of most cities in the west are relatively high, which may lead to poor performance in environmental sustainability.

Key words: entropy method, grey relational analysis, sustainable development
