基于R应用的县级城市综合竞争力比较分析—以X自治区为例

County Urban Comprehensive Competitiveness Comparative Analysis Based on the Application of R—Taking X as an Example

摘要: 城市之间的竞争是市场经济的产物，提高城市的综合竞争力已经吸引了来自各个城市的关注。而X地域辽阔，资源丰富，但地区间的经济差异十分显著，且X城市总体竞争力不高，而如今“一路一带”的构建，使得提高X城市的竞争力迫在眉睫。本文选取了6个一级指标和21个二级指标，构建指标体系，基于R软件运用主成分分析法对X地区19个县级市竞争力进行分层评价。在分析X城市竞争力综合排名的基础上，找出各县级市之间的差异，最终根据评价的结果提出提高各县级市竞争力的对策建议。

Abstract: The competition between cities is the product of market economy. Improving the comprehensive competitiveness of the city has attracted attention from each city. X region has vast territory and rich resources, but the economic differences between regions are very significant, and the X overall urban competitiveness is not high. Now “area” all the way to build and improve the competitiveness of X cities is imminent. This paper has chosen six first-level indexes and 21 secondary indexes, constructing index system, using principal component analysis (pca) based on the R software in X for layered 19 county-level city competitiveness evaluation. On the basis of the analysis of X comprehensive competitiveness ranking, we can find out the difference between each county, finally according to the result of evaluation, put forward some suggestions to enhance the competitiveness of each county.
