The Role of Regional Knowledge Sources for Innovation: An Empirical Assessment

We investigate the contribution of different inputs, particularly different knowledge sources, on regional patenting output in the framework of a knowledge production function. The knowledge sources included are R&D employment, size of public research institutions by field of research (budget), amount of university external research funds from private firms, public departments, German Science Foundation (DFG), and from other sources. The contribution of these knowledge sources is tested systematically on the level of German districts (Kreise) by including the respective information for the particular region and for adjacent regions. One main finding is that the quality of the university research makes some contribution to regional innovation while the mere size of the universities is unimportant. Differences in the effect on innovative output can be found according to academic disciplines and type of university.
