The Integration of Digital Technology dimension measures the digitisation of businesses and e-commerce. By adopting digital technologies, businesses can enhance efficiency, reduce costs and better engage customers and business partners. Furthermore, the Internet as a sales outlet offers access to wider markets and potential for growth. As for the Integration of technology, businesses are the most advanced in Denmark, Finland and Ireland, and the least developed in Romania, Poland and Bulgaria. European businesses are increasingly adopting digital technologies, such as the use of a business software for electronic information sharing (from 26% in 2013 to 34% of enterprises in 2017), sending electronic invoices (from 10% in 2013 to 18% of enterprises in 2016) or using social media to engage with customers and partners (from 15% in 2013 to 21% of enterprises in 2017). eCommerce by SMEs also grew slightly (from 14% in 2013 to 17% of SMEs in 2017). Nevertheless, less than half of these companies sell to another EU Member State.
