This article deals with the evaluation of competitiveness by industries. As a result of the studies of literature and available data, a list of competitiveness indicators is determined and analysed with the perspective of macroeconomic modelling, including the export specialization, the export dependency, the ratio of value added per unit of output, per employee, per unit spent on labour, productivity and unit labour costs. In case of competitiveness studies by industries input-output econometric models are appropriate tools, if adequately specified. Analysis of competitiveness industries shows that high-tech industries are high-value added industries and thus worth focusing on more thoroughly. Medium-high-tech industries seem less developed than medium-low-tech industries in Latvia, thus further studies of factors influencing their development are needed.
