Baltic Europe, i.e. the sea and inland hinterland, form a unique macro-regional unit. Strong collaboration links as well as competition in the Baltic Sea Region are an inherent feature of the region from the beginnings of its civilization development. The article shows the forty-year-long Baltic integration process and the Polish scientific contribution to the process. Since 2004, the Baltic has become an internal EU sea. This fact no doubt strengthened cooperation of the countries around the Baltic Sea. In many spheres, these ties take the form of networking. An important stimulus for further integrations is the EU Strategy for the Baltic Sea Region. Political stabilisation and economic development may transform, in a longer time span, the emerging transnational Baltic Europe into a new economic and cultural European centre.
The purpose of the author was to indicate the deficiency of development management instruments currently used to the territorialization of policies in stimulating intra- and intersectoral partnership cooperation. Her reflections were based on the results of research commissioned by the Polish Ministry of Development and Investment by a team in which the author participated. These studies have revealed that the weakest impacts of the so-called territorial instruments include the ability to mobilize various stakeholder groups to take action and to create partnership cooperation. Against this background, the author has undertaken the analysis of the potential impact of territorial tools on the partnerships development and has attempted to present recommendations for practice and further research in this area.
