||At this stage this paper presents only an outline of a challenging problem. Current statistical data on euroregions continually contribute many interesting elements to be employed by the economic policy of borderline gminas. A detailed formal framework of transborder co-operation, defined by international treaties, stipulates maintaining different forms of such activity. Over the past few years 13 agreements and treaties were made, encompassing all the countries neighbouring with Poland. Euroregions constitute formal entities located along the borders of Poland that are engaged in transborder co-operation. The data disposable indicate that the new idea of euroregions is emerging as a significant political and economic venture. The project is based on the following premise: - Euroregions are located on the territories of 13 countries, including Poland and all of its neighbours / - Euroregions occupy the total of 425 square kilometres and they are inhabited by 36 million people- Euroregions accommodate 33% of Polish population and 27% of its territory. The idea of euroregions is a new, serious challenge for Poland both as a long-term commitment as well a current task. // The following facts indicate the scale of that commitment: - 13 Polish euroregions are located within 14 out of 16 new voivodships / - 13 euroregions accommodate 852 gminas at the Polish side of the border / - 29 % of Polish economic entities listed by the Census Office function within the euroregions territory. //Among the whole community of euroregions four mature regions seem especially promising. These are Pomerania, Pro Europa Viadrina, Sprewa-Nysa-Bóbr, and Nysa. All of them border with the European Union and as such are a real springboard for international co-operation. They include 28 thousand square kilometres of Polish territory, are inhabited by 2.6 million people and accommodate 174 gminas. The paper will describe real estate resources found in those euroregions and indicate the possibilities for their current and future use.
