摘要:Background: Over last years the growing tendency towards the use of barcodes can be observed. They are started to be implemented practically in every activity within the supply chain. The paper presents the analysis of the number of participants of GS1 system in regards to the change of number of companies in Poland and the level of the use of various code systems. The aim of this paper was to identify the main drivers of changes in the implementation of barcodes for multiple packages and trade items among companies in Poland in years 2006-2016. Methods: The decomposition was conducted by the use of LMDI method (Logarithmic Mean Divisia Index). The decomposition analysis was made in the relation to the number of companies enrolled in REGON register. Two indices were used: first one shows the interest in barcodes among companies, the second one relates to total number of companies. Results and conclusions: The results obtained from the decomposition analysis shows factors influencing the interest of companies in code systems: GS1: EAN-13, ITF-14, GS1-128 and SSCC and allows to identify opportunities created by economic growth. They indicate the relationship between the implementation of SSCC identifiers and the interest of companies. The use of GS1 logistics labels should be supported and promoted, and GS1 Poland should play a key role in this activity.
