Abstract
Our primary goal is to analyse the drivers of evolutionary network change processes by using a stochastic actor-based simulation approach. We contribute to the literature by combining two unique datasets, concerning the German laser and automotive industry, between 2002 and 2006 to explore whether geographical, network-related, and techno-logical determinants affect the evolution of networks, and if so, as to what extent these determinants systematically differ for science-driven industries compared to scale-intensive industries. Our results provide empirical evidence for the explanatory power of network-related determinants in both industries. The ‘experience effect’ as well as the ‘transitivity effects’ are significant for both industries but more pronounced for laser manufacturing firms. When it comes to ‘geographical effects’ and ‘technological ef-fects’ the picture changes considerably. While geographical proximity plays an important role in the automotive industry, firms in the laser industry seem to be less dependent on geographical closeness to cooperation partners; instead they rather search out for cooperation opportunities in distance. This might reflect the strong dependence of firms in science-driven industries to access diverse external knowledge, which cannot necessarily be found in the close geographical surrounding. Technological proximity negatively influences cooperation decisions for laser source manufacturers, yet has no impact for automotive firms. In other words, technological heterogeneity seems to ex-plain, at least in science-driven industries, the attractiveness of potential cooperation partners.

Venture Capitalists on Boards of Mature Public Firms
Ugur Celikyurt, Merih Sevilir, Anil Shivdasani
Review of Financial Studies,
Nr. 1,
2014
Abstract
Venture capitalists (VCs) often serve on the board of mature public firms long after their initial public offering (IPO), even for companies that were not VC-backed at the IPO. Board appointments of VC directors are followed by increases in research and development intensity, innovation output, and greater deal activity with other VC-backed firms. VC director appointments are associated with positive announcement returns and are followed by an improvement in operating performance. Firms experience higher announcement returns from acquisitions of VC-backed targets following the appointment of a VC director to the board. Hence, in addition to providing finance, monitoring and advice for small private firms, VCs play a significant role in mature public firms and have a broader influence in promoting innovation than has been established in the literature.

Network Formation: R&D Cooperation Propensity and Timing Among German Laser Source Manufacturers

IWH-Diskussionspapiere,
Nr. 9,
2013
Abstract
Empirical evidence on the evolution of innovation networks within high-tech industries is still scant. We investigate network formation processes by analyzing the timing of firms to enter R&D cooperations, using data on laser source manufacturers in Germany, 1990-2010. Network measures are constructed from a unique industry database that allows us to track both the formation and the termination of ties. Regression results reveal that a firm's knowledge endowment (and cooperation experience) shortens the duration to first (and consecutive) cooperation events. The previous occupation of strategic network positions is closely related to the establishment of further R&D cooperations at a swift pace. Geographic co-location produces mixed results in our analysis.

Zunehmende Internationalisierung der Industrieforschung zeugt von dynamischer Entwicklung der Schwellenländer
Die Internationalisierung von Forschung und Entwicklung (FuE) nimmt seit vielen Jahren zu. Dabei gewinnen die Schwellenländer, allen voran China, für Unternehmen mit Sitz in Deutschland deutlich an Attraktivität. Dies ermittelte ein Gutachten mit dem Titel „Internationale FuE-Standorte“, welches das Institut für Wirtschaftsforschung Halle (IWH) in Zusammenarbeit mit dem Deutschen Institut für Wirtschaftsforschung (DIW Berlin), der Universität St. Gallen (HSG) und der Ludwig-Maximilians-Universität München (LMU) vorgelegt hat. Die im Auftrag der Expertenkommission Forschung und Innovation (EFI) verfasste Studie zeigt die Entwicklungstrends der Internationalsierung von Forschung und Innovation aus der Perspektive des Standorts Deutschland auf.

Innovation im maritimen Cluster von Québec – Auswertung einer regionalen Studie in Québec
Sabine Freye
Presses Académiques Francophones, Saarbrücken,
2013
Abstract
Grundlage der Untersuchung ist die Annahme, dass das Entwicklungspotential einer Industrie bzw. einer Region von ihrer Innovationstätigkeit abhängt. Im Speziellen werden Antworten auf folgende Fragestellungen gesucht: Lässt sich das Cluster-Konzept auf die maritime Industrie der maritimen Region Québecs übertragen? Kann dieser Sektor eine solch große Bedeutung und Wirtschaftskraft erlangen, dass er zu einem wirtschaftlichen Standbein dieser Region werden kann? Der Untersuchung liegen die Umfrageergebnisse einer regionalen Studie zugrunde, die insbesondere die Unternehmenseigenschaften, wie beispielsweise, Größe, Umsatz oder Anzahl der im Unternehmen tätigen Ingenieure, erfasste. Die Ergebnisse zeigen, dass der Großteil der Unternehmen in der untersuchten Stichprobe kleine und mittelständische Unternehmen sind, die nur wenig Innovationsaktivitäten haben. Insgesamt deuten die Ergebnisse darauf hin, dass der untersuchte maritime Sektor nicht die geeigneten Eigenschaften aufweist um dort das Konzept eines Clusters als Regionalentwicklungsstrategie anwenden zu können.

Towards a Theory of Climate Innovation - A Model Framework for Analyzing Drivers and Determinants
Wilfried Ehrenfeld
Journal of Evolutionary Economics,
2013
Abstract
In this article, we describe the results of a multiple case study on the indirect corporate innovation impact of climate change in the Central German chemical industry. We investigate the demands imposed on enterprises in this context as well as the sources, outcomes and determining factors in the innovative process at the corporate level. We argue that climate change drives corporate innovations through various channels. A main finding is that rising energy prices were a key driver for incremental energy efficiency innovations in the enterprises’ production processes. For product innovation, customer requests were a main driver, though often these requests are not directly related to climate issues. The introduction or extension of environmental and energy management systems as well as the certification of these are the most common forms of organizational innovations. For marketing purposes, the topic of climate change was hardly utilized so far. As the most important determinants for corporate climate innovations, corporate structure and flexibility of the product portfolio, political asymmetry regarding environmental regulation and governmental funding were identified.

Exkurs: FuE und Innovation deutscher Unternehmen in Mittel- und Osteuropa – Eine umfragebasierte Analyse
Jutta Günther, Andrea Gauselmann, Björn Jindra
Internationale FuE-Standorte. Studien zum deutschen Innovationssystem Nr. 11-2013,
Nr. 11,
2013
Abstract
Trotz fortschreitender Internationalisierung ist das Gros technologischer Aktivitäten multinationaler Unternehmen in den Konzernzentralen angesiedelt, die sich in den führenden Industrienationen befinden. Allerdings führen multinationale Unternehmen zunehmend Innovationen sowie Forschung und Entwicklung (FuE) auch an ausländischen Standorten durch. In diesem Kontext steigt auch die Bedeutung nachholender Ökonomien als Standorte für FuE sowie Innovation. Dies gilt nicht nur für die rasch wachsenden Wirtschaften Chinas und Indiens sondern auch für die mittel- und osteuropäischen Transformationsökonomien in der Europäischen Union.

Cooperation Events, Ego-Network Characteristics and Firm Innovativeness – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Katja Guhr
IWH-Diskussionspapiere,
Nr. 6,
2013
Abstract
We study how firm innovativeness is related to individual cooperation events and the structure and dynamics of firms’ ego-networks employing a unique panel dataset for the full population of 233 German laser source manufactures between 1990 and 2010. Firm innovativeness is measured by yearly patent applications as well as patent grants with a two year time-lag. Network measures are calculated on the basis of 570 knowledge-related publicly funded R&D alliances. Estimation results from a panel data count model with fixed effects are suggestive of direct innovation effects due to individual cooperation events, but only as long as structural ego-network characteristics are neglected. Innovativeness is robustly related to ego-network size and ego-network brokerage whereas ego-network density reveals some surprising results.
