There are many studies in the regional economics literature which have approached
the issues of regional specialisation and industrial concentration. Regional
specialisation depicts the distribution of the sectoral shares in one region,
usually compared to the rest of the country, while geographic concentration of a
specific industry reflects the distribution of its regional shares. In order to explore
the main characteristics and the interaction between regional specialisation and
sectoral concentration in Romania and to achieve a better understanding of the
topic, we have used “traditional” statistical measures like the Herfindahl Index
and Krugman Dissimilarity Index. Concentration of industries and specialisation
of regions were measured for the 1996-2005 period on the basis of the Gross Value
Added and employment data, by branch and by region, provided by Romanian
official statistics.
