International trade statistics are generally classified in the terms of products and trade quantities between countries. Export sophistication is a nascent method of measuring how much the export size of countries has a capital-intensive product composition. Due to export sophistication, which can also be expressed as an index of development based on income levels of exporting economies, research and development expenditures and unit export prices, countries can be characterized by their sophistication in exports. In this study, unit exports prices were calculated by dividing the total exports by the total export unit quantity of each country in each HS Code chapters. Cluster analysis was used with per capita R&D expenditures and the sophistication index based on the unit export prices. The countries were classified due to these criteria. Consequent of this classification analysis, 6 different clusters of countries were identified. As a result of the analysis, it was found that the innovation gap is a decisive factor in the export sophistication.
