This paper deals with the problems of regional economic integration in the
German-Polish border area, focusing on the nature and intensity of cross-bo
rder inter-firm linkages. It firstly emphasizes the differentiation of regi
onal development paths in East Central Europe, contrasting a 'high road' an
d a 'low road' to development. Then the problems of cross-border regional i
ntegration are discussed with regard to exogenous and endogenous influences
. Exogenous influences on the development of the border region include the
investment strategies of western firms in former East Germany and Poland. E
ndogenous influences include communication barriers and a 'low trust enviro
nment' which is rooted in the particular development history of this region
. These factors help to explain why only weak and qualitatively 'low level'
approaches to economic co-operation between regional firms on both sides o
f the border have emerged.
