Firms’ embeddedness into knowledge networks has received much attention in the literature. However, little is known about the composition of firms’ ego-networks with respect to different types of proximities. Based on survey data of 295 firms in eight European regions, we show that the...

A growing body of work emphasizes the importance of regional factors for regional innovativeness. In this paper, about seventy variables approximating the social-economic characteristics of regions are aggregated to twelve regional factors. In four industry-specific set-ups their influence on...

The importance of geographical proximity for interaction and knowledge sharing has been discussed extensively in economic geography in recent years. There is increasing consensus that it is just one out of many types of proximities that might be relevant. We argue that proximity may be a crucial...

Studies analyzing the importance of intra- and inter-regional cooperation for regional innovation performance are mainly of qualitative nature and focus strongly on the positive effects that high levels of cooperation can yield. For the case of the German labor market regions and the Electrics &...

The importance of R&D subsidies for innovation activities is highlighted by numerous firm-level studies. These approaches miss however the systematic regional character of innovation activities and potential firm-spanning effects of this policy measure. The literature on regional innovation...

Although a rich literature has emerged analyzing the impact of localization, urbanization, and Jacobs externalities on regional innovativeness, the findings are still contradictory. Traditional studies differ mainly in the employed data but rely on similar empirical approaches. This paper argues...

The paper investigates the impact of R&D subsidies on regional innovation efficiency. Building on a rich panel data set covering 270 German labor market regions and four industries, it is particularly shown that subsidies for R&D cooperation are a suitable policy measure for stimulating the...

Measuring the innovation performance of regions or nations has been repeatedly done in the literature. What is missing in the literature is a discussion of what innovation performance of a region means. How do regions or nations contribute really to the innovation output of firms? And how can...

We investigate the lead-lag relationship between growth of patent applications, growth of R&D, and growth of total sectoral employment for 270 German labour market regions over the period 1999-2005. Our unique panel dataset includes information on four two-digit industries, namely Chemistry,...

A key question raised in recent years is which factors determine the structure of inter-organizational networks. While the focus has primarily been on different forms of proximity between organizations, which are determinants at the dyad level, recently determinants at the node and structural...
