Abstract The aim of this research is to determine the minimum number of uncorrelated dimensions which can describe national competitiveness (NC). NC is thought of as the ability of a nation to provide a conducive environment for its firms to prosper. It is shown that the environment affects national productivity catalytically through the interactions with the production factors while itself remaining unchanged. Selected World Economic Forum’s indicators are used for determining the components of the environment. The Principal Component Analysis has revealed three orthogonal dimensions of NC. Countries are represented by the points in the three-dimensional space. The weighted Euclidean distance from the origin to the ith point is proposed as a novel measure of the ith country’s level of NC.

国家竞争力的维度：基于世界经济论坛数据的实证分析

摘要这项研究的目的是确定可以描述国家竞争力（NC）的最小不相关维数。NC被认为是一个国家为其公司发展提供有利环境的能力。结果表明，环境通过与生产要素的相互作用而催化地影响了国民生产率，而环境本身却保持不变。选定的世界经济论坛的指标用于确定环境的组成部分。主成分分析揭示了NC的三个正交维度。国家由三维空间中的点表示。提出了从原点到第i个点的加权欧几里得距离，作为第i个国家的NC水平的一种新颖度量。
