Innovationskooperationen deutscher Unternehmen im europäischen und innerdeutschen Vergleich
The study deals with innovation cooperation as a means to improve the competitiveness of enterprises. The empirical study compares the cooperation behaviour of innovative enterprises in Germany to other West European countries as well as between East and West Germany. The database used is the second Community Innovation Survey (CIS-2) of the EU. While German firms exhibit a cooperation frequency slightly below the average of the European Economic Area (EEA), enterprises in North European countries are by far most active with respect to cooperation frequency. The most important cooperation partner for firms in the EEA are other firms within the enterprise group, followed by suppliers and customers while German firms cooperate most frequently with universities. The comparative investigation of innovation cooperation in East and West Germany shows that East German firms cooperate more often than West German firms. However, a productivity advantage of cooperating firms against non-cooperating firms is only observable in West Germany. In East Germany, cooperating firms even exhibit a lower sales productivity than non-cooperating firms, which is explainable most probably through the fact that cooperation activities translate into productivity advantages only in the long run.
