Foreign Direct Investment (FDI) are regarded as the most effective form of international capital flows. The term FDI is often used in conjunction with globalisation, liberalisation and internacionalisation of the world economy. This paper deals with analysis of development of FDI in Visegrad countries (V4) after eastern enlargement of the EU, especially development of geographical and structural trends. The main analysis comes out of an analysis of business environment in individual Visegrad countries. Last but not least, the paper deals with FDI effects concerning not only positive aspects of FDI but also negative aspects connected with the FDI inflows in V4 which are arising currently as a consequence of global financial and economic crisis.
