The regions development characterisation by diversity/variety of the firms - study case for Romania

In this paper we try to find empirical evidence regarding the region diversity by firm characteristics, using spatial data from Tempo (INS Romania database) at NUTS 1, 2 and 3 region level for the period 1997-2008. Using instruments of statistical analysis of spatial data (Anselin, Varga) we try to sketch the spatial pattern of firm agglomerations and values of main firm's characteristics (size class according to employee's number and economic activity by NACE Rev.1 sections). Starting point is represented by the discussion made by Saviotti(*) regarding the efficiency vs diversity/variety in economic development respectively development versus growth. The pattern variation of the regions "profile" by diversity/variety of the firms could offer an image for the structural transformation of economic development tendencies of it in the last decade.
