Innovation, regional knowledge spillovers and R&D cooperation

چکیده
We investigate the impact of knowledge spillovers and R&D cooperation on innovation activities in three German regions. We begin by estimating the knowledge-production function in order to test for interregional difference with regard to the efficiency of innovation activities. In a second step, we analyze the contribution of spillovers from R&D effort of other private firms and of public research institutions to explain these differences. The inclusion of variables for R&D cooperation in the model indicates that R&D cooperation is only of relatively minor importance as a medium for knowledge spillover. © 2003 Elsevier B.V.

متن کاملA cointegration panel data analysis for international R&D spillovers and R&D cooperation: case study for Mediterranean countries
In this paper, we consider R&D cooperation and direct foreign investment as a channel of international spillovers by an empirical literature on innovation and growth. First, spillovers are limited to the country where R&D is conducted; the growth rate in each country will be determined by the country’s own R&D-efforts and by R&D cooperation ignored a long time in growth literature. Second, spil...
متن کاملInnovation, Demand and Knowledge Spillovers: Theory and Evidence from European Regions
The Importance of innovation for the economic performance of industrialized countries has been largely stressed recently by the theoretical and empirical literature. Very few studies have carefully considered the determinants of European innovation, the productivity of its R&D and the existence of knowledge spillovers across regional boundaries. Here we develop a model which, emphasizing “the d...
متن کاملThe Role of National Innovation Programs in Stimulating International Cooperation in Innovation
Abstract. The impacts of innovation programs may go far beyond improvements in private R&D expenditures and patents. In this paper we propose that domestic-level programs, not necessarily designed to increase international links in science and technology, may indirectly foster international cooperation in innovation, by providing additional funding, experience in domestic collaboration, and lea...
