Abstract
Was treibt regionale Entwicklung? Warum wachsen einige Regionen schneller als andere? Diese Fragen stehen im Mittelpunkt regionalökonomischer Forschung. Einen besonderen Anwendungsfall stellen die ökonomischen Anpassungsprozesse im Gefolge der Wiederherstellung der Deutschen Einheit dar. Nach einem fulminanten Start in der ersten Hälfte der 1990er Jahre hat sich der Aufholprozess seit Mitte der 1990er Jahre verlangsamt und kommt seitdem nur noch in sehr kleinen Schritten voran. Im Jahr 2017 betrug die Produktivität Ostdeutschlands (mit Berlin) 82% des westdeutschen Niveaus. Über die Ursachen dieses Rückstands gibt es intensive Diskussionen.

Delineation of City Regions Based on Commuting Interrelations: The Example of Large Cities in Germany

Abstract
The comparison of cities with regard to their economic or demographic development may yield misleading results, if solely the cities in their administrative borders are the object of consideration. Frequently, historical borders of cities neither conform to the contemporary settlement structures, nor do they consider the mutual dependencies between cities and parts of their hinterland. Therefore, it is often claimed to use city regions as objects of comparison or for the sake of urban planning. Commonly, the delineation of functional regions is based on commuting flows from the municipalities in the hinterland of the core cities directed to the cores. A municipality is regarded as belonging to a certain city region if the share of out-commuters from this municipality to the respective core in the total mass of those employees who reside in that municipality is the largest one, and if this share exceeds a certain threshold value. However, commuting flows in the opposite direction are not considered. The method presented here delineates city regions on the base of bidirectional commuting flows. Hereby, various modifications regarding the characteristics of the employment base, the possibility of overlaps of regions, the formation of polycentric city regions, and of the minimum threshold value of mutual connectivity are applied to the sample of 81 German cities with more than 100 000 inhabitants. Finally, the effects of different kinds of regionalisation on the coefficients of regional specialisation of these cities and city regions are demonstrated.

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.
