Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.

Industry Concentration and Regional Innovative Performance – Empirical Evidence for Eastern Germany
Christoph Hornych, Michael Schwartz
Post-Communist Economies,
2009
Abstract
Regarding technological innovativeness, the transformed economy of the former German Democratic Republic (GDR) clearly lags behind the western part of the country. To face this weakness a broad mixture of policy measures was carried out in recent years. Particular attention is drawn to the development of industry concentrations and economic ‘clusters’. However, little is known about the effectiveness of these policy measures regarding how industry concentrations in fact promote innovative performance in Eastern Germany. The present study tries to fill this gap by analysing the relationship between industry concentration in Eastern Germany and regional innovative performance. Our empirical analysis is based upon the number of patent applications of 22 manufacturing industries in 22 Eastern German planning regions. The estimated regression models indicate an inverted-U relationship between the degree of industry concentration and innovative performance. An exceedingly high degree of industry concentration in one region hampers regional innovative output. We discuss policy implications of our findings and give recommendations for future refinement of ‘cluster’-supporting policy schemes in Eastern Germany.

The Manufacturing Sector in East Germany on a Path from De-industrialization to Re-industrialization: Are there Economically Sustainable Structures?
Gerhard Heimpold
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
Der Beitrag untersucht, welche Entwicklung die ostdeutsche Industrie in der Zeit nach dem Übergang in die Marktwirtschaft genommen hat und ob die hinter den wirtschaftlichen Ergebnissen stehenden Faktoren und Strukturen Merkmale wirtschaftlicher Nachhaltigkeit aufweisen. Gemessen an den wirtschaftlichen Ergebnissen wurde seit Beginn der 90er Jahre viel erreicht: Die Bruttowertschöpfung ist auf das Zweieinhalbfache gestiegen, die industrielle Produktivität liegt bei reichlich vier Fünfteln des westdeutschen Vergleichswertes. Die Produktivitätssteigerung allerdings ging mit einer Halbierung der Industriebeschäftigung im Zeitraum von 1991 bis 2008 einher, trotz eines leichten Zuwachses in den Jahren 2006 bis 2008. Die Lage und Entwicklung der Industrie in den einzelnen Neuen Ländern stellt sich allerdings sehr unterschiedlich dar. Beim industriellen Beschäftigtenbesatz liegt das Bundesland Thüringen vor einigen westdeutschen Bundesländern.
Bei den hinter den Ergebnissen stehenden Faktoren und Strukturen deutet nicht alles auf ökonomische Nachhaltigkeit hin. Zwar wurde im Vergleich zur westdeutschen Industrie überdurchschnittlich viel in die Modernisierung des Sachkapitalstocks investiert, und beim Humankapital verfügt die ostdeutsche Industrie über einen Anteil von Beschäftigten mit Hoch- und Fachschulabschluss, der jenem in Westdeutschland entspricht. Doch bei den Forschungs- und Entwicklungs-(FuE-)Aktivitäten, die für ökonomisch nachhaltige, sprich zukunftsgerichtete, Industrieaktivitäten stehen, offenbaren sich gemessen an wichtigen Inputgrößen Defizite. Letztere resultieren aus den strukturellen Besonderheiten der ostdeutschen Industrie, zu denen nicht zuletzt die Dominanz kleiner und mittlerer Unternehmen und das Fehlen größerer Unternehmen gehören. Mit der inputseitig schwach ausgeprägten FuE im Unternehmenssektor korrespondiert ein vergleichsweise geringer Anteil technologieintensiver Branchen, während der Anteil arbeitsintensiver Branchen höher als in den Alten Bundesländern ausfällt. Ein weiterer Wandel hin zu nachhaltigeren Industriestrukturen wird also nottun. Denn aus wachstumstheoretischer Sicht lässt sich ein dauerhafter Wachstumspfad hauptsächlich mit technologieintensiven Produktionen verwirklichen. Arbeitsintensive Branchen stehen dagegen im internationalen Wettbewerb besonders unter Kostendruck. Auch die funktionalen Strukturen offenbaren in puncto ökonomischer Nachhaltigkeit Defizite. Der Anteil von Beschäftigten in industriellen Fertigungsfunktionen liegt über den westdeutschen Verhältnissen, und jener in hochwertigen -Dienstleistungs- ebenso wie in den übrigen Dienstleistungsfunktionen liegt darunter. Dies weist erneut auf den Mangel an Unternehmen mit Führungsfunktionen in den Neuen Ländern hin. Will die ostdeutsche Industrie auf dauerhaftem Wachstumskurs bleiben, wird demnach ein weiterer Strukturwandel zugunsten technologie- und humankapitalintensiver Produktionen erforderlich sein, den die Wirtschaftspolitik durch günstige Rahmenbedingungen unterstützen sollte.

Regional Growth and Finance in Europe: Is there a Quality Effect of Bank Efficiency?
Iftekhar Hasan, Michael Koetter, Michael Wedow
Journal of Banking and Finance,
No. 8,
2009
Abstract
In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures of financial institutions. Contrary to the usual quantitative proxies of financial development, the quality of financial institutions is measured in this study as the relative ability of banks to intermediate funds. An improvement in bank efficiency spurs five times more regional growth then an identical increase in credit does. More credit provided by efficient banks exerts an independent growth effect in addition to direct quantity and quality channel effects.

Einzelveröffentlichungen,
No. 4,
2008
Abstract
Modern biotechnology is one of the key enabling technologies of the 21st century with a potentially wide range of applications in many sectors, including health, agriculture and industrial processes. Considering the potential of modern biotechnology to contribute to the achievement of major European Union policy goals, such as economic growth and job creation, public health, environmental protection and sustainable development, the European Parliament has requested the European Commission to carry out an assessment of modern biotechnology. The European Commission welcomed the initiative and announced to undertake a study “to conduct a cost benefit analysis of biotechnology and genetic engineering, including genetically modified organisms in the light of major European policy goals formulated in the Lisbon Strategy,

Is There a Way for Old Industrial Districts to Become Attractive for Cultural Industry? The Case of Media Businesses in Halle (Saale), Germany
Martin T. W. Rosenfeld, Christoph Hornych
IWH Discussion Papers,
No. 15,
2008
Abstract
manufacturing have collapsed are trying to stimulate entrepreneurial activities of businesses in the cultural industry. The question is whether this strategy could be successful. This article examines the strategy of supporting the sector of Media Industry (´MI´) by policy makers in the region of Halle in East Germany, where a strong de-industrialization has taken place after the German reunification. Stimulated by the policy makers’ support measures, there actually was a remarkable development of MI. However, the number of MI firms and their employees did not further increase in recent years, after having reached a certain level. This illustrates the limits of political measures for turning a city’s path of industrial development voluntarily.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 58,
2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.
