The aim of the study is to determine the nature of e-commerce socio and economic effects in Ukraine, Poland, and Austria. For analysis, a modern mathematical apparatus was used – the Cobb-Douglas model and the Markov chain methodology. The study shows a significant positive impact of e-commerce on employment and GDP in the three countries. Thus, with an increase in investment levels in e-commerce and ICT by 1%, employment in Ukraine will increase by 0.02%, in Poland – by 0.14%, and in Austria – by 0.17%.
