How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?

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 externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

A Control Group Study of Incubators’ Impact to Promote Firm Survival
Michael Schwartz
Wirtschaft im Wandel,
No. 7,
2010
Abstract
For more than half a century, publicly funded business incubators (BIs) are at the heart of urban and regional technology and innovation policies. However, it is widely unclear as to whether start-up firms supported by publicly-initiated incubator initiatives have higher survival rates than comparable start-up firms that have not received support by such initiatives. The present article contributes to the underlying discussion by performing an empirical analysis of the long-term survival of 371 incubator firms (after their graduation) from five German BIs and contrasting these results with the long-term survival of a control group of 371 comparable non-incubated firms. The analysis covers a 10-year time span. For neither of the five incubator locations, we find statistically significant higher survival probabilities for firms located in incubators compared to firms located outside those incubator organizations. For three incubator locations the analysis even reveals statistically significant lower chances of survival for those start-ups receiving support by an incubator. We therefore arrive at the conclusion that being located in an incubator does not increase the chances of long-term business survival.

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-model of Interregional Migration Flows in Germany
Lutz Schneider, Alexander Kubis
Schmollers Jahrbuch,
2010
Abstract
The article analyses the question of whether women and men differ in their tastes for location factors. The question is answered by quantifying the impact of location characteristics on interregional migration flows across Germany. The analysis is based on a grouped conditional logit approach. We augment the framework by controlling for violation of the independence of irrelevant alternatives assumption and for overdispersion. As a result we find no differences in terms of direction of impact; however, the regressions confirm gender differences, mostly in terms of intensity, regarding regional wage levels and the availability of educational institutions. Moreover, even after controlling for place attributes women seem to be more migratory than men.

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.

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.

A Panel Data Analysis on China's Intra-Industry Trade in the Capital Goods Sector
Yiping Zhu
IWH Discussion Papers,
No. 18,
2009
Abstract
This paper adopts the Hausman-Taylor 2SLS error components approach in estimating the determinants of China's Intra-Industry Trade (IIT) in the capital goods sector with its 26 partner countries. It disaggregates IIT into horizontal IIT (HIIT) and vertical IIT (VIIT). Capital goods final products and intermediates are separately estimated in order to reveal the differentiated trade patterns. It finds that economic similarity is very significantly negatively correlated with the intermediates IIT, but to a less extent correlated with the final products IIT. Factor endowment is of no significance in determining IIT in the intermediates, although it is significantly positively correlated with the final products IIT. Economic size is significantly negatively correlated with both final products and intermediates IIT. Distance is not yet dead in impacting the level of final products IIT, but of less importance in influencing the intermediates IIT. China is exchanging intermediates in a less intraindustry manner with ASEAN nations. However, because VIIT is dominating TIIT, no significant differences exist between the estimation results of TIIT and VIIT.

Abstract
The contribution analysis the impact of the average age and experience of employees on the firm’s productivity using the linked employer employee data set from the IAB (LIAB). The inquiry is restricted to the manufacturing sector and distinguishes between a low-tech and a high-tech sector. We find an inverted u-shaped relationship between age and productivity. Experience supports productivity, however, the experience based effects are too small to compensate the negative impact of age at higher stages.

Out-migration and Regional Convergence
Alexander Kubis, Lutz Schneider
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
Since 1989, the migration deficit of East Germany has accumulated to 1.8 million people. Against this background, the contribution analyses the relationship between regional migration and regional growth. From a theoretical point of view, one might find reasons in favour and in opposition to a convergence supporting function of migration. If migrants are taken from the upper tail of the human capital distribution of a poor region, divergence is the probable outcome. If on the other hand people with low human capital endowment move to richer regions, migration might enhance regional convergence.
The empirical analysis how regional migration and convergence are interrelated is performed on the basis of German districts within a period from 1995 to 2006. The concept of ß-convergence is applied and a cross-section model controlling for spatial correlation between the error terms is estimated.
The results indicate convergence on the regional level; East German regions seem to catch up particularly fast. The effect of migration is twofold. Out-migration from poor region is correlated with strong growth in these regions. However, the corresponding migration towards richer region is accompanied with growth in these regions, too. Therefore, the impact of migration on convergence is uncertain. Nevertheless, the outcome is in favour of an aggregate benefit of migration if people move from poor to rich regions.
