ABSTRACT
The contributions to this volume draw upon a wide range of experience. Nevertheless they share a common interest in planning and policy making at the transnational level. The transnational dimension in planning and policy making takes many different forms ranging from the need to devise statistical measures which promote comparability between many different countries, to indepth investigations of a single country. However, in all cases, the researchers are not primarily concerned with the country or countries in their own right but from the standpoint of comparative analysis, even though this is sometimes implicit rather than explicit in the discussion.
