Matched firm-level balance sheet and partner- and product-level foreign trade data can be used to examine the relationship between product mix and productivity of firms, as well as other characteristics, such as size or foreign ownership. The conclusions to be drawn on the basis of foreign trade data are supplemented by the results of analyzes with production and domestic sales data. For this and for the longitudinal analysis of foreign trade data, the two classification systems had to be harmonized. It can be stated that the production and domestic sales data only partially support the conclusions that can be drawn from the foreign trade data. However, according to foreign trade data, the important components of the expansion of the export range are the expansion of the import range, the firm size, the productivity, and the foreign ownership.
