Abstract
The Photovoltaic-(PV)-Industry is a comparatively new industrial sector which is affected by high level of uncertainty. This uncertainty is derived from different technology paths as same as uncertainty about the future market developments. Important instruments to come up with uncertainty are firm networks. Thereby the state of the knowledge about the degree of interconnectedness between the German PV-industry is poor. This article aims to close this gap by giving an overview about the integration of PV-enterprises in firm networks.
The empirical analysis of the network structure of the German PV-industry thereby confirms the expected high level of network relations. Almost nine out of ten firms cooperate with other PV-firms in Germany. Also, the intensity of cooperation turns out to be above the average compared to other industrial sectors. On average one PV-firm cooperates with 5.8 other PV-firms. This indicates possibilities for a better knowledge exchange in the sector. Overall the high cooperation intensity supports the assumption that PV-industry is able to benefit from the spatial concentration of the industry in the region.
Despite the dense network which has already emerged, the promotion of networks can still be an efficient paradigm to support innovativeness and growth in this sector. This is going to be even more successful if the results of the network analysis are integrated into the government supporting scheme.

Market Concentration and Innovation in Transnational Corporations: Evidence from Foreign Affiliates in Central and Eastern Europe
Liviu Voinea, Johannes Stephan
Research on Knowledge, Innovation and Internationalization (Progress in International Business Research, Volume 4),
2009
Abstract
Purpose – The main research question of this contribution is whether local market concentration influences R&D and innovation activities of foreign affiliates of transnational companies.
Methodology/approach – We focus on transition economies and use discriminant function analysis to investigate differences in the innovation activity of foreign affiliates operating in concentrated markets, compared to firms operating in nonconcentrated markets. The database consists of the results of a questionnaire administered to a representative sample of foreign affiliates in a selection of five transition economies.
Findings – We find that foreign affiliates in more concentrated markets, when compared to foreign affiliates in less concentrated markets, export more to their own foreign investor's network, do more basic and applied research, use more of the existing technology already incorporated in the products of their own foreign investor's network, do less process innovation, and acquire less knowledge from abroad.
Research limitations/implications – The results may be specific to transition economies only.
Practical implications – The main implications of these results are that host country market concentration stimulates intranetwork knowledge diffusion (with a risk of transfer pricing), while more intense competition stimulates knowledge creation (at least as far as process innovation is concerned) and knowledge absorption from outside the affiliates' own network. Policy makers should focus their support policies on companies in more competitive sectors, as they are more likely to transfer new technologies.
Originality/value – It contributes to the literature on the relationship between market concentration and innovation, based on a unique survey database of foreign affiliates of transnational corporations operating in Eastern Europe.

Abstract
. If regional development agencies assume the cluster concept to be an adequate framework to promote regional growth and competitiveness, it is necessary to identify industrial clusters in a comprehensive manner. Previous studies used a diversity of methods starting with specific regional case studies, input-output methods and different concentration measures. This article presents a new instrument in empirical cluster research – the Qualitative Input-Output Analysis –, which offers the possibility to identify industrial cluster in conjunction with concentration measures. Especially, this method allows the combination of an identified critical mass of regional firms with the necessity of interaction of these firms within an input-output framework. Applying this method to Germany’s “Arbeitsmarktregionen” we find that 103 “Arbeitsmarkregionen“ show first signs of horizontal industrial clusters, while only 28 regions are able to attract vertical industrial clusters. 139 “Arbeitsmarktregionen” did not show signs of industrial clusters according to the research design.

A Multidimensional Evaluation of the Effectiveness of Business Incubators: An application of the PROMETHEE outranking method
Michael Schwartz, Maximilian Göthner
Environment and Planning C: Government and Policy,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that focused on the effectiveness of incubator initiatives and how to measure incubator performance, there is still a lack of understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, the present article concentrates on this crucial question and compares the long-term effectiveness of five BIs in Germany by applying the multi-criteria outranking technique PROMETHEE. In particular, we investigate whether PROMETHEE is a well suited methodological approach for the evaluation and comparisons in the specific context of business incubation.

Spatial Distribution of East German Innovative Competencies: Significant Increase in the Southwestern Hinterland of Berlin and in the Centres of Saxony and Thuringia
Peter Franz
Wirtschaft im Wandel,
No. 9,
2007
Abstract
Patent applications constitute an essential indicator for the extent of innovative activities in an economy or region. Due to the fact that innovative activities are in general spatially concentrated, policy makers perceive in this information starting points for a growth-oriented regional policy. Against this background, the Halle Institute for Economic Research (IWH) in 2004 had examined the spatial distribution of industries, firm networks and innovative competencies in the context of an area-wide study for East Germany. Newly available data for the patent statistics allow for an updating of these results regarding the innovative competencies for the time period from 2000 to 2005. In comparison to the time period between 1995 and 2000, an increase in innovative competencies becomes evident. This growth takes place almost exclusively in regions where innovative competencies are already domiciled. All in all, the growth dynamics of East Germany with regard to patent applications is slightly behind the West German one. The distribution of technological fields, to which the applied patents refer to, remained largely constant during the two observation periods. In the area of bio-technology, electrical engineering and of health care the standing of East Germany has further improved. With regard to political implications, the data should not be used for imposing technology specific support programs. Instead a tax relief for R&D independent of the used technologies seems to be more adequate.

Threshold for employment and unemployment. A spatial analysis of German RLM's 1992-2000
Christian Dreger, Reinhold Kosfeld
External Publications,
2006
Abstract
Changes in production and employment are closely related over the course of the business cycle. However, as exemplified by the laws of Verdoorn (1949, 1993) and Okun (1962, 1970), thresholds seem to be present in the relationship. Due to capacity reserves of the firms, output growth must exceed certain levels for the creation of new jobs or a fall in the unemployment rate. While Verdoorn's law focuses on the growth rate of output sufficient for an increase in employment, in Okun's law, the fall in the unemployment rate becomes the focus of attention. In order to assess the future development of employment and unemployment, these thresholds have to be taken into account. They serve as important guidelines for policymakers. In contrast to previous studies, we present joint estimates for both the employment and unemployment threshold. Due to demographic patterns and institutional settings on the labour market, the two thresholds can differ, implying that minimum output growth needed for a rise in employment may not be sufficient for a simultaneous drop in the unemployment rate. Second, regional information is considered to a large extent. In particular, the analysis is carried out using a sample of 180 German regional labour markets, see Eckey (2001). Since the cross-sections are separated by the flows of job commuters, they correspond to travel-to-work areas. Labour mobility is high within a market, but low among the entities. As the sectoral decomposition of economic activities varies across the regions, the thresholds are founded on a heterogeneous experience, leading to more reliable estimates.The contribution to the literature is twofold. First, to the best of our knowledge, no previous paper has investigated a similar broad regional dataset for the German economy as a whole before. By using a panel dataset, information on the regional distributions around the regression lines as well as theirs positional changes is provided for each year. Second, the methods applied are of new type. They involve a mixture of pooled and spatial econometric techniques. Dependencies across the regions may result from common or idiosyncratic (region specific) shocks. In particular, the eigenfunction decomposition approach suggested by Griffith (1996, 2000) is used to identify spatial and non-spatial components in regression analysis. As the spatial pattern may vary over time, inference is conducted on the base of a spatial SUR model. Due to this setting, efficient estimates of the thresholds are obtained. With the aid of a geographic information system (GIS) variation of the spatial components can be made transparent. With Verdoorn’s and Okun’s law the figures show some significant patterns become obvious over time. In respect to Verdoorn’s law, for instance, a stripe of high values in the north-western part from Schleswig-Holstein via Lower Saxony and North Rhine Westfalia to Rhineland Palatinate is striking in all years but 1994 and 1995. In most periods the spatial component is likewise concentrated in Saxony. Clusters of low values can be found in northern Bavaria and, in some periods, in Thüringen and Mecklenburg-Vorpommern. Other parts of Germany appear to be more fragmented consisting of relative small clusters of low, medium and high values of the spatial component. With Okun’s law some changing spatial patterns arise. In all, spatially filtering provides valuable insights into the spatial dimensions of the laws of Verdoorn and Okun.

Economic Development in Saxony-Anhalt: empirical results and policy recommendations
Franz Barjak, Peter Franz, Gerhard Heimpold, Martin T. W. Rosenfeld
Wirtschaft im Wandel,
No. 3,
2001
Abstract
Though the basic economic problems are still of the same kind all over East Germany, partially considerable regional differences exist in respect to the conditions for further economic development. Therefore, detailed empirical analyses for the individual Länder and their sub-regions are necessary making economic policy recommendations. The following contribution deals with this task taking Saxony-Anhalt as an example.
A multitude of indicators is used to bring out the specific strengths and weaknesses of the economy of this state (Land) and its sub-regions. The outstanding strength of Saxony-Anhalt are the high private investment outlays which served to build a modern capital stock during the past ten years. Another fundamental strength of the Land are the universities and public research institutions. Besides these unambiguous strengths some ‘ambivalent’ growth factors exist which are characterized by strengths as well as by weaknesses. Such ‘ambivalent’ growth factors are the infrastructure and the situation of important sectors and branches of economic activity. The weaknesses of Saxony-Anhalt’s economic structure find expression especially in its low supply with human capital and entrepreneurial initiative as well as in the few research and development efforts of its firms.
The aforementioned strengths of the Land are reflected insufficiently in its economic output. Consequently some economic policy measures are proposed to bring about an improvement: Amongst other things Saxony-Anhalt should develop a clear idea of its economic development (Leitbild). Such a Leitbild could be related to the Land’s strengths or to the elimination of its major weaknesses. This also would facilitate a concentrated use of the different economic policy instruments. The latter shouldn’t only be concentrated on singular economic growth factors but also spatially, on the economically stronger sub-regions, as this can lead to larger growth effects for the entire Land. The good provision with public research institutions in Saxony-Anhalt should be used to bring about an improvement of the economic structure to a larger extent than until now. This could be done for example by means of a further strengthening of applied research vs. basic research, possibly via orienting the public research more towards the existing branches of economic activity. Finally, the Land should intensify its efforts to increase the entrepreneurial initiative in Saxony-Anhalt, e. g. by means of introducing courses in economics in its schools.
