The 'cluster theory' has become one of the main concepts promoting regional competitiveness, innovation, and growth. As most empirical applications focus on measures of concentration of one industrial branch in order to identify regional clusters, the appropriate analysis of specific vertical relations is developing in this discussion. This paper tries to identify interrelated sectors via national input-output tables with the help of minimal flow analysis (MFA). The regionalization of these national industry templates is carried out with the allocation of branch-specific production values on regional employment. As a result, the paper shows concentrations of vertical clusters in only 27 of 439 German Nomenclature des Units Territoriales Statistiques (NUTS)-3 regions.

This paper explores the impact of industrial clusters on regional growth at the German labour market region level using a regional convergence model. Based on the results of an exploratory study of the geography of German industrial clusters, we are able to differentiate the impact of industrial clustering from a horizontal and a vertical perspective while taking regional convergence into consideration. The results indicate that in addition to an all-German process of convergence, a specific East German one can be identified. The different types of industrial clusters show mixed effects within this framework. While vertically isolated industrial clusters have a negative impact on regional growth in this period, positive growth effects can be identified when industrial clusters show an intra-regional vertical interconnectedness.

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 to identify the predominant concentrations of economic activity in one industrial sector in a region. This paper is based on a multidimensional approach developed by Titze et al. With the help of the combination of concentration measures and input–output methods they were able to identify horizontal and vertical dimensions of industrial clusters. This paper aims to refine this approach by using a superior measure of spatial concentration and by integrating information about spatial interdependence of industrial cluster structures to contribute to a more adequate framework for industrial cluster identification.

Die vergangenen Jahrzehnte waren weltweit durch eine Zunahme der außenwirtschaftlichen Ungleichgewichte gekennzeichnet. Den Leistungsbilanzüberschussländern, insbesondere Deutschland, wird in diesem Zusammenhang zunehmend vorgeworfen, durch zu moderate Lohnsteigerungen wesentlich zum Aufbau der Ungleichgewichte beigetragen zu haben. Vor diesem Hintergrund werden im vorliegenden Beitrag auf Basis einer Paneldatenanalyse die Determinanten der Leistungsbilanzungleichgewichte in der Europäischen Union ermittelt. Die Ergebnisse zeigen, dass die internationale preisliche Wettbewerbsfähigkeit der Länder nur eine von vielen erklärenden Variablen darstellt. Vielmehr gehen die Ungleichgewichte wesentlich auf unterschiedliche Sparneigungen, sowohl der öffentlichen Hand als auch des privaten Sektors, zurück. Folglich wären die an Deutschland gerichteten Forderungen, zum Abbau der Ungleichgewichte die moderate Lohnpolitik zu beenden, allein nicht zielführend. Stattdessen müssen andere Wege gefunden werden, die Binnennachfrage in den Leistungsbilanzüberschussländern zu stärken und die Ausschöpfung bestehender Sparpotenziale in den Leistungsbilanzdefizitländern zu erhöhen.

Folgt man der Überlegung, dass das Clusterkonzept für die regionale Wirtschaftspolitik Ansatzpunkte bildet, um Wirtschaftswachstum sowie Wettbewerbsfähigkeit von Regionen zu fördern, so setzt dies voraus, industrielle Cluster umfassend zu identifizieren. Bisherige Untersuchungen bedienen sich dazu einer methodischen Vielfalt, ausgehend von spezifischen regionalen Fallstudien über Input-Output-Methoden hin zu verschiedenen Konzentrationsmaßen. Der vorliegende Beitrag verwendet ein für die empirische Clusterforschung neues Instrument – die Qualitative Input-Output-Analyse. Ihr wohnt nach Ansicht der Autoren die Möglichkeit inne, in Verbindung mit Konzentrationsmaßen einen Beitrag zur flächendeckenden Identifikation industrieller Cluster zu liefern. Insbesondere erlaubt die vorgestellte Methodik die Zusammenführung des Tatbestandes einer kritischen Masse von Unternehmen mit dem Merkmal der Interaktion dieser über Input-Output-Beziehungen auch auf größeren regionalen Untersuchungsebenen. Wendet man die Methodik auf die deutschen Arbeitsmarktregionen an, so wird ersichtlich, dass 103 von 270 Arbeitsmarktregionen über Ansätze horizontaler Cluster verfügen, weitere 28 Regionen beherbergen vertikale industrielle Cluster. 139 Arbeitsmarktregionen weisen gemäß dem gewählten Untersuchungsdesign weder horizontale noch vertikale Cluster auf.

Even though state aid in order to rescue or restructure ailing companies is regularly granted by European governments, it is often controversially discussed. The aims for rescuing companies are manifold and vary from social, industrial and even political considerations. Well-known examples are Austrian Airlines (Austria) or MG Rover (Great Britain). Yet, this study aims to answer the question whether state aid is used effectively and whether the initial aim why aid has been paid has been reached, i.e. the survival of the company. By using data on rescued companies in the EU and applying a survival analysis, this paper investigates the survival rates of these companies up to 15 years after the aid has been paid. In addition, the results are compared to the survival rates of non-rescued companies which have also been in difficulties. The results suggest that despite the financial support, business failure is often only post-poned; best survival rates have firms with long-term restructuring, enterprises in Eastern Europe, smaller firms and mature companies. However, non-funded companies have an even higher ratio to go bankrupt.

The paper presents estimates for the impact of related variety, unrelated variety and the functions a region performs in the production process on regional employment growth in Germany. We argue that regions benefit from the existence of related activities that facilitate economic development. Thereby the sole reliance of the related and unrelated variety concept on standard industrial classifications (SIC) remains debatable. We offer estimations for establishing that conceptual progress can be made when the focus of analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety and test our hypothesis by the help of spatial panel approach. Our findings suggest that related variety as same as unrelated variety facilitate regional employment growth in Germany. However, the drivers behind these effects do differ. While the positive effect of related variety is driven by high degrees of relatedness in the regional “R&D” and “White-Collar”-functions, the effects of unrelated variety are spurred by “Blue Collar”-functions in this period.
