This study is a summary of a master's thesis defended at the Faculty of Economic Sciences of the University of Warsaw. The aim is to examine what factors condition the absorption of modern technologies. Particular attention was focused on determinants related to human capital, organizational capital and the broadly understood business environment. Using a series of regressions based on data on 14 sectors in 21 OECD countries from 2012-2018, it was shown that both human and organizational capital are important complementary factors to modern technologies. Moreover, market regulations, especially those related to the labor market and stimulating the innovation of economies, play an important role in the adoption of digital technologies and strengthen the positive impact of human and organizational capital in the diffusion of modern technological solutions.
