Abstract
In the article the Polish transfrontal policy is analysed at the end of ХХ – at the beginning of ХХІ ages, that is characterized the wide palette of connections in political, economic, ecological, infrastructural, educational, cultural and humanitarian spheres. Development of transfrontal collaboration of Poland for period 1995–2005 was very much an important factor not only from point of development actually of boundary regions but also in the context of acceleration of the European integration process of country on the whole. Among Central Europe countries Poland was one of more active participants of transfrontal collaboration. It is found out, that RP is the transfrontal leader of region of Central Europe. Indisputably, that every boundary region has the specific descriptions, both positive and negative. However, will mark that a level of development of transfrontal collaboration of regions of Poland is excellent, in fact every level has both the features and depends on a nearby partner for other side of border. To our opinion, political will of sides, activity of territorial organs of power is the base condition of transfrontal collaboration. Coordination of efforts of sides is sent, foremost, on implantation of the European legal field in a national legislation, overcoming of asymmetry of development. An Ukrainian-Polish transfrontal collaboration is characterized prevailing of barrier function of border, high level of centralization of power, low bringing in, to the collaboration of local societies. After east expansion of European Union in 2004 – for the Ukrainian side new instruments and mechanisms, new instituty forms, were opened, consequently, new possibilities of transfrontal collaboration.
