The research analyzing and assessing the influence of history, culture, religion, lifestyle and other, difficult to measure, quality factors - defining the identity of societies and nations - on the functioning and development of enterprises, are carried out, among others, by applying the central conceptual category, i.e. national management style (NMS). The question is whether and why the concept of national knowledge management style (NKMS) creates the new cognitive framework and quite likely opens the interesting areas of scientific expansion? You can venture the hypothesis, that the conditions are created by history, culture, religion, legislation, lifestyle and other factors which altogether establish the unique space for running a business, stimulate particular attitudes, behaviours and decisions referring to e.g. knowledge management. The examples of developed countries and their socio-economic systems indicate that in this respect we face the specific factors creating the unique relations of adequate determinants. National economies of such countries as USA, Japan, Germany, France, Great Britain, etc. represent the best examples. The study identifies the Japanese, German and American approach to knowledge management (Nonaka, Takeuchi 1995; Yoo, Torrey 2002). Currently this conceptual category can be used for analogous research and searching for an answer to the question about the specific nature of knowledge management in Eastern and Central European countries. This category, as the research direction, practically does not occur at the background of management science in Poland (Mroziewski 2002). In the context of presented discussion the important research problem should be considered as defining the specific characteristics of Polish national knowledge management styles (NKMS), their influence on the selected business functioning areas: human capital management, for example.
