基于动态因子分析法的中部六省省会城市竞争力比较与分析

Central six province capital city competitiveness comparison and analysis based on dynamic factor analysis method

动态因子分析是将主成分分析得到的截面分析结果和线性回归模型得到的时间序列分析结果进行综合的一种多元统计分析方法,这种方法通过加入时间变量能够客观全面地反映城市竞争力的动态变化和综合发展情况。本文通过STATA统计分析工具,试图运用动态因子分析法对我国中部六省省会城市竞争力进行比较分析,结果表明:目前武汉市是中部地区综合竞争力最强的城市,郑州、长沙具有较强的竞争力,合肥、南昌和太原三个城市的综合竞争力排名靠后,在中部六省会城市平均水平之下。

The dynamic factor analysis（DFA）,integrated the cross-section analysis results through Principal Component Analysis（PCA） and time series analysis results through linear regression model,is a multivariate statistical analysis method,which can reflect the dynamic change and development of urban competitiveness objectively and comprehensively by adding the time variable.Using the STATA statistical analysis tools,this paper applies dynamic factor analysis to the comparative analysis of urban competitiveness for the capital city of China＇s six central provinces.The results show that： Wuhan is the most competitive of the central regions.The city of Zhengzhou and Changsha has strong competitiveness.Hefei,Nanchang and Taiyuan is ranked the last three in the comprehensive competitiveness,the level of which are below the average of the six cities.
