We use goods export data at the SITC 3-digit level to analyse countries’ world market-share developments in 2002–2024. We divide the data into technological
categories and use an existing econometric method with annual weighted-OLS to divide the market-share changes into estimated structural composition effects (export destinations and exported products) and performance effects. Typically, emerging economies have grown stronger through performance, but older industrialised countries have partly compensated their performance-induced market-share losses with a better product composition of exports. Finland and Italy are exceptions as countries that have also had a weak export product composition. We further analyse the performance changes of European countries’ exports using an econometric panel data analysis with data for GDP variables, nominal unit labour costs and effective exchange rates, investment, and statistics on the activities of multinational corporations. We find that investment and FDI activity are positively associated with performance.
