Zmiany wartości polskiego eksportu w ujęciu Trade in Value Added na tle krajów Grupy Wyszehradzkiej

Abstract

Research on export based on domestic value added greatly complements the knowledge about the gross export of a given country. This measure provides not only information on trade flows, but also makes it possible to determine how much they are the result of work carried out in a given country and to what extent they depend on other links of value chains. The Trade in Value Added (TiVA) database, created by OECD and the WTO, provides such information. However, the data tend to be rarely analysed and presented in public discourse. The aim of the study presented in the paper is to show the changes in Polish export based on TiVA. In order to create a complete picture of the situation of Poland, the data covering TiVA for Poland were compared with analogous results obtained for the other Visegrad Group countries, whose economies share similar historical and geopolitical conditions: the Czech Republic, Slovakia and Hungary. The study uses data covering the period between 2004 (the year Poland joined the EU) and 2018 (the last year available in the database) and applies descriptive and statistical methods. The main hypothesis of the paper, stating that TiVA in Polish export grows relatively slower than the value of export measured in the traditional way, was verified. Additionally, a supporting hypothesis, assuming that TiVA in Polish export increases relatively slower than in the other researched countries, was also examined. The analysis shows that Poland has a significantly higher percentage of domestic value added in export and the dynamics of the changes in this factor is higher compared to the other Visegrad Group countries. Nevertheless, the growth rate of Polish gross export measured in the traditional way is higher than the export measured according to TiVA.
