摘要:

旨在对中国各直辖市和省会城市的可持续发展能力进行评估.首先构建包括经济、社会和环境子系统在内的较为合理的可持续发展指标体系.在运用熵值法对各指标客观赋权后,运用灰色关联法计算基于熵权的关联度,对各城市可持续发展能力进行定量评价.结果表明,东部城市总体上可持续发展能力强于中部、西部和东北部地区,但某些城市的各子系统之间发展不均衡,存在制约其进一步发展的短板;部分中西部城市在经济和社会发展方面表现突出,具有很强的发展潜力;由于受到产业结构、技术水平等方面的影响,大多数西部城市的污染物排放强度较高,在环境可持续发展方面表现欠佳.

关键词: 熵值法, 灰色关联, 可持续发展

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
