The Research of the Foreign Trade Competitiveness in Dynamic Approach on the Example of Poland

One of the study proposals of the intensity of the intra-industry trade was presented Glejser et al. (1982). It is competitive with many foreign trade indicators which do not take account of the country specialization in import and export and do not refl ect adequately the effects of trade imbalances. On based the variance of the export and import specialization indicators Glejser et al. (1982) created a tool that overcomes these shortcomings. The proposed method, however, was not equipped with an appropriate statistical and econometric tools, which greatly limits its practical usefulness. This article attempts to improve the method and test it on the example of foreign trade in Poland.
