No. 6,

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.

European Planning Studies,
No. 11,
2013
Abstract
The spatial evolution of the German solar industry is analysed in the light of the “window of locational opportunity” and the “selection environment” approach. The paper argues that differences in the regions' ability to promote the emergence of local external economies contribute to increasing regional differentiation in the German structure of the industry. Applied empirical methods enclose longitudinal firm entry and network analysis. A special focus is given upon the realignment processes in the science system. Our findings show a relatively rapid spatial concentration of production in eastern Germany since the year 2000. This process is accompanied by intensified networking between firms and between firms and universities as well as research institutes. The responsiveness of regional institutions and the self-organizing capabilities of the solar firms substantiate some propositions of the “selection environment” approach.

Determinants of Evolutionary Change Processes in Innovation Networks – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Andreas Pyka, Jutta Günther
Abstract
We seek to understand the relationship between network change determinants, network change processes at the micro level and structural consequences at the overall network level. Our conceptual framework considers three groups of determinants – organizational, relational and contextual. Selected factors within these groups are assumed to cause network change processes at the micro level – tie formations and tie terminations – and to shape the structural network configuration at the overall network level. We apply a unique longitudinal event history dataset based on the full population of 233 German laser source manufacturers and 570 publicly-funded cooperation projects to answer the following research question: What kind of exogenous or endogenous determinants affect a firm’s propensity and timing to cooperate and enter the network? Estimation results from a non-parametric event history model indicate that young micro firms enter the network later than small-sized and large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected yet quite interesting findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of contextual determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

Wirtschaft im Wandel,
No. 12,
2011
Abstract
Der Beitrag analysiert das Kooperationsgeschehen in der deutschen Photovoltaik-Industrie. Ausgehend von den theoretischen Vorteilen, die Kooperationen in stadt- und regionalökonomischen Ansätzen zugeschrieben werden, wird geprüft, inwieweit die tatsächlich bestehenden Kooperationsmuster in den verschiedenen Bundesländern den aus theoretischer Sicht günstigen Kooperationsmustern entsprechen. Hierzu erfolgt eine vergleichende Beschreibung der Kooperationsstrukturen der Industrie in und zwischen den einzelnen Bundesländern. Die Untersuchung basiert auf der „IWH-Unternehmensdatenbank Photovoltaik“, die u. a. Informationen zu den Kooperationsbeziehungen zwischen den in der Datenbank enthaltenen Unternehmen und öffentlichen Forschungseinrichtungen enthält. Die Ergebnisse zeigen, dass sich die Kooperationsintensitäten in und zwischen den Bundesländern deutlich voneinander unterscheiden. Dabei sind insbesondere die mitteldeutschen Bundesländer Sachsen, Sachsen- Anhalt und Thüringen durch eine starke gegenseitige und deutschlandweite Vernetzung gekennzeichnet. Hingegen sind die Akteure in der Region Berlin-Brandenburg, die ähnlich wie Mitteldeutschland durch eine hohe
Konzentration an Photovoltaikunternehmen gekennzeichnet ist, deutlich weniger in Netzwerkstrukturen eingebunden.

Cooperation propensity and public cooperation funding in the German Laser Industry
Muhamed Kudic, Katja Guhr, I. Bullmer, Jutta Günther
Wirtschaft im Wandel,
No. 3,
2011
Abstract
Die Hightech-Strategie der Bundesregierung definiert acht Schlüsseltechnologien, zu denen unter anderem die optischen Technologien und somit die Laserstrahlquellenhersteller zählen. Der Beitrag stützt sich auf aktuelle empirische Auswertungen und gibt einen ersten deskriptiven Überblick über den wissensintensiven Industriezweig der Laserstrahlquellenhersteller in Deutschland zwischen 1990 und 2010. Es zeigt sich, dass die Industrieentwicklung im Betrachtungszeitraum Schwankungen unterlag, in der Summe jedoch durch Expansion gekennzeichnet war. Zudem lässt sich eine hohe Präsenz vor allem von Großunternehmen der Laserstrahlquellenindustrie in Bayern, Baden-Württemberg und Thüringen feststellen. Diese regionalen Verteilungsmuster lassen sich im Hinblick auf die Partizipation an öffentlich geförderten Kooperationsprojekten wiederfinden, allerdings nur bei Betrachtung der absoluten Zahl von Verbundprojekten je Bundesland. In Relation zur Anzahl der Firmen im jeweiligen Bundesland wird die öffentliche Kooperationsförderung insbesondere in Thüringen, Rheinland-Pfalz und Hamburg stark nachgefragt. Somit ergibt sich für die räumliche Verteilung der Kooperationsintensität und Kooperationsförderung pro Firma ein differenziertes Muster.

Analyzing Innovation Drivers in the German Laser Industry: the Role of Positioning in the Social and Geographical Space
Muhamed Kudic, Peter Bönisch, Iciar Dominguez Lacasa
Abstract
Empirical and theoretical contributions provide strong evidence that firm-level performance outcomes in terms of innovativeness can either be determined by the firm’s position in the social space (network effects) or by the firm’s position in the geographical space (co-location effects). Even though we can observe quite recently first attempts in bringing together these traditionally distinct research streams (Whittington et al. 2009), research on interdependent network and geographical co-location effects is still rare. Consequently, we seek to answer the following research question: considering that the effects of social and geographic proximity on firm’s innovativeness can be interdependent, what are the distinct and combined effects of firm’s network and geographic position on firm-level innovation output? We analyze the innovative performance of German laser source manufacturers between 1995 and 2007. We use an official database on publicly funded R&D collaboration projects in order to construct yearly networks and analyze firm’s network positions. Based on information on population entries and exits we calculate various types of geographical proximity measures between private sector and public research organizations (PRO). We use patent grants as dependent variable in order to measure firm-level innovation output. Empirical results provide evidence for distinct effect of network degree centrality. Distinct effect of firm’s geographical co-location to laser-related public research organization promotes patenting activity. Results on combined network and co-location effects confirms partially the existence of in-terdependent proximity effects, even though a closer look at these effects reveals some ambiguous but quite interesting findings.

On the Determinants of the Cooperative Behavior of Firms in the German Photovoltaic Industry
Christoph Hornych, Matthias Brachert
IWH Discussion Papers,
No. 20,
2010
Abstract
Wenn gleich die positiven Effekte von Kooperationen bereits in einer Vielzahl von Untersuchungen nachgewiesen werden konnten, erfährt die Frage nach den Determinanten der Neigung von Unternehmen, Kooperationsbeziehungen einzugehen, in der Forschung zu Unternehmenskooperationen bisher nur geringe Aufmerksamkeit. Dabei könnte die Kenntnis der relevanten Einflussfaktoren Aufschluss darüber geben, inwieweit sich unterschiedliche Kooperationsintensitäten in Regionen auf Unterschiede im Unternehmensbesatz zurückführen lassen. Vor diesem Hintergrund untersucht das Diskussionspapier, welche Einflussfaktoren die Anzahl der Kooperationspartner von Unternehmen in der Photovoltaik-Industrie bestimmen. Ausgehend von einem Überblick über die möglichen Effekte der Kooperation von Unternehmen mit Partnern innerhalb und außerhalb der eigenen Region werden Hypothesen über die Zusammenhänge zwischen sowohl unternehmensspezifischen als auch regionsspezifischen Variablen und der Kooperationsneigung von Unternehmen aufgestellt. Diese werden im Rahmen von Regressionsmodellen anhand eines Datensatzes zu 178 deutschen Photovoltaikunternehmen getestet. Die Ergebnisse zeigen, dass insbesondere große Unternehmen sowie Unternehmen mit hohen absorptiven Fähigkeiten eine Vielzahl an Kooperationsbeziehungen unterhalten. Kooperationen innerhalb der eigenen Region gehen die Unternehmen vor allem dann ein, wenn eine Vielzahl potenzieller Partner am Standort vorhanden ist. Zudem kooperieren Niederlassungen ausländischer Unternehmen besonders häufig mit Partnern aus der Region, in der sie angesiedelt sind.

Mutual Perception of Science and Industry in Innovation Networks – Evidence from East Germany
Jutta Günther, Cornelia Lang
D. Dyker (ed.), Network Dynamics in Emerging Regions of Europe, Imperial College Press,
2010
Abstract
The paper examines how science and industry perceive each other. Cooperation in the field of innovation and research and development has increased in recent years. But comprehensive empirical research on the mutual perception of science and industry is lacking so far. The article presents the results of explorative research based on a number of qualitative interviews with representatives from science and industry on that topic. The interviews were carried out in the Central German Region which is a centre of manufacturing industry especially of chemicals. So the two selected industries are chemical industry (high-tech based) and food processing (low-tech based). The paper provides remarks on the German innovation system. The empirical section summarizes the interview reports. We found only little evidence of conflict of interests between market-oriented industry and science organisations. Cooperation exists and works. The key issue is trust.

Cooperation Patterns of Incubator Firms and the Impact of Incubator Specialization: Empirical Evidence from Germany
Michael Schwartz, Christoph Hornych
Technovation,
2010
Abstract
The article examines cooperation patterns of 150 firms located in German business incubators (BIs). More specifically, this study distinguishes between networking within the tenant portfolio and the academic-industry linkages of the tenant firms. We further contribute to the relevant literature by explicitly considering differences in cooperation patterns between firms located on diversified and specialized incubator facilities. Empirical results do not support the common assumption that specialized incubation strategies increase the effectiveness of incubator-internal networking compared to diversified BIs. Also, incubator specialization is not superior to diversified incubators with respect to the promotion of linkages of their tenants with academic institutions. For academic linkages, industry effects matter more than incubator characteristics.

Challenges for Future Regional Policy in East Germany. Does East Germany really show Characteristics of Mezzogiorno?

Abstract
Despite extensive government support the gap between East and West Germany has still not been successfully closed nearly 20 years post German unification. Hence, some economists tend to compare East Germany with Mezzogiorno – underdeveloped Southern Italy. East Germany is still subject to sever structural problems in comparison to West Germany: lower per capita income, lower productivity, higher unemployment rates, fewer firm headquarters and fewer innovation activities. There are East German regions with less than desirable rates of development. Nevertheless, the new federal states have shown some evidence of a convergence process. Some regions have developed very positively – they have improved their competitiveness and employment levels. As such, the comparison of East Germany with Mezzogiorno does not seem applicable today.
According to Neoclassical Growth Theory, regional policy is targeted enhancing investment (hereafter the notion ‘investment policy’ is used). has been the most important instrument in forcing the ‘reconstruction of the East’. Overall, the investment policy is seen as having been successful. It is not, however, the only factor influencing regional development – political policy makers noted in the mid 1990s that research and development (R&D) activities and regional concentrated production networks, amongst other factors, may also play a part. The investment policy instrument has therefore been adjusted. Nevertheless, it cannot be excluded that investment policy may fail in particular cases because it contains potentially conflicting targets. A ‘better road’ for future regional policy may lie in the support of regional production and innovation networks – the so-called industrial clusters. These clusters would need to be exactingly identified however to ensure effective and efficient cluster policies.
