Abstract-This study, part of an ongoing global study, aims to advance information society research and practice by examining and understanding the information and communication technologies (ICT) adoption in enterprises in the context of the sustainable information society (SIS). In this study, the ICT adoption is described by four components. i.e. outlay on ICT, information culture, ICT management, and ICT quality, whereas the sustainability is composed of ecological, economic, socio-cultural, and political sustainability. This study employs a quantitative approach to identify the levels of ICT adoption and sustainability in enterprises as well as investigate the correlation between these two constructs. The survey questionnaire was used and data collected from 394 enterprises were analyzed. The research findings reveal that there were significant statistical differences between the highest level of outlay on ICT and the lowest ones, namely the levels of ICT quality and ICT management. Moreover, the economic sustainability was at the highest level, whereas the lowest and similar levels were specific to ecological and political sustainability. Finally, it is investigated that the ICT quality, ICT management, and information culture have a significant impact on the sustainability, whereas the outlay on ICT does not have such an impact. This study advances the information society research and practice by measuring the ICT adoption, sustainability and correlation between them in the Polish enterprises.
