The main purpose of the paper is to assess the level of EU countries’ ability to compete in a sustainable manner and to compare these results with achievements in the area of sustainable competitive position. In the paper, the definition of the new economic category – sustainable competitiveness and its main components: sustainable competitive capacity and sustainable competitive position, as well as these new terms’ measurement proposal were presented. The study is also an attempt to the exploration of relationship existing between those categories. For this purpose, the selected statistical methods were applied. The taxonomic measure of development as well as the correlation coefficients, were used to measure the multilevel relationship between those considered areas. Until now, those categories were presented only in the context of examining the countries’ ability to compete sustainably. However, the aspects of sustainable competitive position have been completely ignored. That’s why it should be emphasized that this kind of investigation is a novelty in the area of sustainable competitiveness. The research results confirmed the existence of relationship between the various areas that consist to the holistic concept of sustainable competitiveness. These relationships are not always strong though and this is the crucial fact for further research in this area.

可持续竞争力作为一个新的经济类别——定义和衡量评估

本文的主要目的是评估欧盟国家以可持续方式竞争的能力水平，并将这些结果与可持续竞争地位领域的成就进行比较。本文提出了新经济类别——可持续竞争力的定义及其主要组成部分：可持续竞争能力和可持续竞争地位，以及这些新术语的衡量建议。该研究也是对这些类别之间存在关系的探索。为此，应用了选定的统计方法。发展的分类测量以及相关系数被用来测量这些考虑区域之间的多层次关系。到现在，这些类别只是在审查各国可持续竞争能力的背景下提出的。然而，可持续竞争地位的方面被完全忽略了。这就是为什么应该强调这种调查是可持续竞争力领域的新事物的原因。研究结果证实了构成可持续竞争力整体概念的各个领域之间存在联系。然而，这些关系并不总是牢固的，这是该领域进一步研究的关键事实。研究结果证实了构成可持续竞争力整体概念的各个领域之间存在联系。然而，这些关系并不总是牢固的，这是该领域进一步研究的关键事实。研究结果证实了构成可持续竞争力整体概念的各个领域之间存在联系。然而，这些关系并不总是牢固的，这是该领域进一步研究的关键事实。
