Related Variety, Unrelated Variety and Regional Functions: Identifying Sources of Regional Employment Growth in Germany from 2003 to 2008
Matthias Brachert, Alexander Kubis, Mirko Titze
Abstract
This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that facilitate economic development. However, we argue that the sole reliance of related variety on standard industrial classifications remains debatable. Hence, we offer estimations for establishing that conceptual progress can indeed be made when a focus for analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety. Our findings suggest that related variety only in combination with a high functional specialization of the region facilitates regional growth in Germany. Additionally, also unrelated variety per se fails to wield influences affecting development of regions. It is rather unrelated, but functionally proximate variety in the groups “White Collar” and “Blue Collar Workers” positively affects regional employment growth.

Metropolitan Area „Central Germany“: How Strong are the Commuting Flows between the Cities?
Albrecht Kauffmann
Wirtschaft im Wandel,
No. 2,
2011
Abstract
Die Metropolregion Mitteldeutschland ist ein Bündnis zur Kooperation zwischen den großen Städten in den Ländern Sachsen, Sachsen-Anhalt und Thüringen. Angesichts der Vielzahl der beteiligten Städte sowie der großen Entfernungen zwischen den Städten an den Rändern und dem geographischen Zentrum der Region stellt sie einen Sonderfall innerhalb der derzeit elf in Deutschland existierenden Europäischen Metropolregionen dar. Eine Besonderheit ist auch der Umstand, dass bislang eine Festlegung des Umlands der Kernstädte fehlt. Der Beitrag untersucht die Vernetzung zwischen den beteiligten Städten anhand von Pendlerverflechtungen. Darüber hinaus werden erstmals mögliche Abgrenzungen des Umlands der Metropolregion Mitteldeutschland im Sinne einer funktionalen Stadtregion diskutiert. Es erweist sich, dass die Vernetzung innerhalb der vormaligen Metropolregion Halle/Leipzig-Sachsendreieck und der Thüringer Städtekette deutlich stärker in Erscheinung tritt als die Pendlerbeziehungen
zwischen diesen historisch gewachsenen Regionen. Als funktionale Stadtregion besäße die Metropolregion Mitteldeutschland ein weit gespanntes, jedoch eher dünn besiedeltes Umland, das nur mit den nahegelegenen Kernstädten enge Verflechtungen aufweist. Insgesamt zeigt sich, dass zwischen den traditionell einander näher stehenden Städten eine bessere Basis für Kooperationen vorhanden ist, deren verstärkte Nutzung dem Anliegen der Metropolregion Mitteldeutschland jedoch nicht zuwiderlaufen muss.

Abstract
Die Abteilung Stadtökonomik des IWH veranstaltete am 2. und 3. Dezember 2010 das dritte „Halle Forum on Urban Economic Growth“. Auf der im zweijährigen Turnus stattfindenden Konferenz werden Forschungsergebnisse zu wesentlichen Einflussfaktoren der wirtschaftlichen Entwicklung von Städten präsentiert. Das dritte „Halle Forum“ widmete sich der Frage nach den Formen und Vorteilen von Kooperationen und Vernetzung für die wirtschaftliche Entwicklung von Städten und Metropolregionen. In den Vorträgen und Diskussionen wurden die Effekte und Determinanten von inter- und intraregionalen Kooperationen zum einen zwischen Unternehmen, zum anderen zwischen benachbarten Kommunen thematisiert. Ein besonderer Fokus lag dabei auf der Zusammenarbeit von Städten im Rahmen der Etablierung von Metropolregionen, mit denen die nationale und internationale Wettbewerbsfähigkeit der betreffenden Städte verbessert werden soll.

Political Institutionalisation and Economic Specialisation in Polycentric Metropolitan Regions – The Case of the East German ‚Saxony Triangle‘
Peter Franz, Christoph Hornych
Urban Studies,
2010
Abstract
The rising focus of politicians as well as scientists in the EU on the large urban agglomerations as centres of economic growth is accompanied by political efforts to identify and to demarcate such agglomerations under the label ‘metropolitan regions’. This study develops a theoretical framework broaching the issue of cooperation between municipalities from the perspective of regional economics as well as political science. The framework is applied to the empirical case of the polycentric metropolitan region of the ‘Saxony triangle’ in east Germany. The results show that various intervening factors prevent intense co-operation between the actors in the region. Policy implications and conclusions for future research are discussed.

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.

Knowledge Spill-overs for Knowledge-based Development: Progression in Theory and Obstacles for Empirical Research
Peter Franz
International Journal of Knowledge-Based Development,
2010
Abstract
As scientists and policymakers tend to interpret changes in the economy as a trend towards an increasingly knowledge-based economy, their recommendations and strategies for regional economic development frequently contain elements how to intensify the knowledge flows in the region concerned. Knowledge flows come into existence from intentional action, but also in an unintended way as externalities or knowledge spillovers. This paper reviews the ways regional and urban economics has dealt with the concept of knowledge spillovers. Knowledge spillovers are defined within a conceptual framework that points out different uses of knowledge in economics. The concept’s operationalisations in diverse empirical studies are systematised and discussed. After a critical review of the current state of research, policy strategies aiming to intensify knowledge spillovers are classified. The paper concludes with an outlook on promising new approaches to research knowledge spillovers and on the elaboration of more efficient policy strategies.

How to Make a City Attractive for Knowledge-Intensive Firms? – The Formation and Stagnation of Media Industry in the Old Industrial Region of Halle (Germany)
Christoph Hornych, Martin T. W. Rosenfeld
The Regeneration of Image in Old Industrial Regions: Agents of Change and Changing Agents. Mönchengladbacher Schriften zur wirtschaftswissenschaftlichen Praxis, Bd. 22,
2009
Abstract
In many regions with development problems, which had – in the past – been the domain of traditional industries, policymakers are trying today to stimulate entrepreneurial activities in knowledge-intensive and creative industries. The question is whether this strategy could really be successful. This paper reports on a case-study for the region of Halle an der Saale, which is located in the state of Saxony-Anhalt (East Germany), where the strategy of policymakers has recently been the attempt to support firms from Media Industry (“MI”).

Urban Growth in Germany – The Impact of Localization and Urbanization Economies
Christoph Hornych, Michael Schwartz, Annette Illy, Martin T. W. Rosenfeld
IWH Discussion Papers,
No. 19,
2009
Abstract
This study examines the impact of localization and urbanization economies as well as the impact of city size on urban growth in German cities from 2003 to 2007. Although, from a theoretical perspective, agglomeration economies are supposed to have positive impacts on regional growth, prior empirical studies do not show consistent results. Especially little is known about agglomeration economies in Germany, where interregional support policy and the characteristics of the federal system are further determinants of urban growth. The results of the econometric analysis show a U-shaped relationship between specialization and urban growth, which particularly holds for manufacturing industries. We do not find evidence for the impact of Jacobs-externalities; however, city size shows a positive (but decreasing) effect on urban growth.
