This paper explores the localness of Greek prefectures according to the methodological approach of economic base and, specifically, the minimum requirements technique, which leads to the estimation of a localness index for each group of prefectures of similar population size. Hence, through the definition of the types of areas that enhance their localness, the determination of the spatial pattern and the causes of these changes could be better investigated. According to the results of the research, a growing localness in all groups of prefectures during the period 2000–2009 has emerged. Localness seems high in a group with the highest population and largest urban concentrations, enhancing their ability to be largely self‐powered locally. Localness is high in the smallest group too, which is characterized by the pattern of integrated spatial development. Thus, without underestimating the importance of exports and imports, it makes more sense to look at localness and extroversion together in order to achieve greater development.

Purpose The purpose of this paper is to examine the multiplier effects of economic activities in the local economy of Greek non-metropolitan prefectures at NUTS3 level according to the Eurostat classification. Design/methodology/approach A disaggregate economic base model using OLS regression with clustered standard errors is implemented in 49 non-metropolitan prefectures and 17 economic activities for 2000 and 2012. The specific model indicates a clear picture of multiplier effects of economic activities among the prefectures as it has a similar logic to the input-output analysis while bearing in mind the spatial effects among prefectures. The specific model has not applied for testing base multipliers in the Greek economy according to the academic literature. Findings Non-traditional export-oriented activities play a significant role in the economic growth of the non-metropolitan prefectures. Their multiplier effects are higher than the traditional basic activities. Especially, some of these activities indicate strong shifts on specific local activities, which tend to be the significant multiplier effects on the overall local economy. Of course, the existence of agglomeration economies plays a considerable role in non-metropolitan prefectures with a significant population and non-metropolitan prefectures which are in insular space or belong to the perimetric and interior mountainous space, which are sparsely populated. Originality/value The specific model applies at the NUTS3 level, according to the Eurostat classification. Also, the model indicates that the multiplier effects come from non-traditional export activities, such as, information-communication, arts entertainment, health services, professional support services and real estate in the overall local economy. Finally, the spatial correlation influences the sectoral multipliers.
