城市生态-社会-经济综合分析指标体系筛选方法

Research on Screening Methods of Indicators System on Urban Ecology-Society-Economy Synthetical Analysis

通过对国内外可持续发展、全面发展、协调发展以及生态文明建设等指标体系的借鉴,初选出城市生态-社会-经济综合分析指标体系。基于指标设计原则,构建了城市综合分析基本指标。综合运用相关系数法和变异系数法,建立了我国城市综合分析指标体系。研究结果表明,相关性分析删除相关系数大的指标,避免了信息重复;变异系数分析删除变异系数偏小和偏大的指标,能够使指标既有较强的鉴别能力,又有较好的稳定性,从而保证了指标体系的科学性。

The indicators system on urban ecology-society-economy synthetical analysis is firstly selected after domestic and overseas indicators systems on sustainable development,integrated development,coordinated development,and ecological civilization construction are used for reference. Based on the principles on indicator design,then the basic urban synthetical analysis indicators are constructed. Furthermore,urban synthetical analysis indicators system in China is established by combination of correlation methods and variable coefficient methods. The result shows that correlation analysis has the advantage of avoiding of information repetition by deleting the indicators with high correlation coefficient. And variable coefficient analysis can improve the resolution capability and stability of the indicators by deleting the higher or lower variable coefficient. Both of the two methods ensure the scientificness of the indicators system.
