基于改进主成分的省域投资环境竞争力评价指标体系研究

The Competitiveness Evaluation Research for Provincial Investment Environment in China Based on Modified Principal Component Analysis

以全国31个省(直辖市、自治区)的面板数据为基础,从社会环境、经济环境、基础设施和自然环境四个维度出发,基于改进的主成分与聚类方法,构建了省域投资环境竞争力评价指标体系与竞争力评价模型,对省域投资环境竞争力评价进行排名和区域分类。研究发现,我国省域投资环境竞争力排名呈现东强西弱的阶梯状分布,与我国区域经济发展水平分布格局基本一致,且各省域的投资环境竞争力与其吸引外资的业绩呈显著正相关;我国省域投资环境竞争力可分为4大类7小类,体现了部分省份投资环境的相似性和差异性。经Wilcoxon符号秩检验,排名与凤凰湖北发布的竞争力排名基本一致。

The paper uses the data from 31 provinces all over China in 2013 to study the provincial investment environment competitiveness,making rankings and regional classifications for it. To achieve that,we start from four demotions which are social environment,economy environment,infrastructure,and natural environment to construct the index system for competitiveness evaluation of provincial investment environment with the basement of competitiveness evaluation model and clustering analysis. It is found that the provincial investment environment competitiveness rankings show the feature of ladder-like distribution that the rankings in eaten areas are higher than that in western areas. The feature is almost the same as the regional economic development level in China. Also,there is a significantly positive correlation between the provincial investment environment competitiveness and the performance of absorbing foreign capital. In China,we could divide the provincial investment environment competitiveness into four categories and seven small classes to indicate the similarities and differences among different investment environment in some certain provinces. Besides,through Wilcoxon signed rank test,the ranking result is consistent with that published by Phoenix of Hubei. The conclusion helps the improvement for investment environment of all provinces in China and provides guidance and advice for foreign tradesmen to make scientific decisions of area investment.
