Instituto Superior de Economia e Gestão. DE Working papers nº 27-2010/DE/UECE0874-4548http://hdl.handle.net/10400.5/2865We use constant market share (CMS) analysis to measure the variations in the market share of 82 of the world’s principal exporting countries between 1995/97 and 2005/07. The results of this analysis serve to stress the importance of competitiveness in explaining export performance. Furthermore, the existence is observed of a spatial tendency, reflected in the fact that countries that are geographically close to each other tend to display a similar behavior with regard to market share evolution and the components into which the variation is broken down.engConstant Market ShareCompetitivenessExport PerformanceInternational Tradeworking paper
