    Dramatical changes in society’s infrastructure require new conceptual approaches towards the research of socioeconomic
phenomena. Nowadays, environment surrounding people experience qualitative changes; it has become possible to use full information
on the history of objects. It is essential to develop a conceptual framework enabling to thoroughly describe the interaction of an
individual and a socioeconomic environment that is changed by digital technologies. In this article, it is suggested to use the concept of
socioeconomic technology in the context of exploration of digitalization processes. These include the Internet of things, big data
processing, widespread implementation of personal tools to process and share information etc. The concept of socioeconomic technology
allows tying up new technologies with the needs of an individual and society as well as with phenomena emerging in socioeconomic
infrastructure. The suggested approach may be used at the development and implementation of the Internet of things, of global
communication infrastructure, of technologies for processing and storage of data, and for the research of other aspects of society’s
digitalization. Today it is possible to research different directions for the development of consumption sphere and technologies taking
into account the emergence of virtual properties of objects. Virtual properties result for example in multiple ways to implement things,
in the possibility to store and use the full history of major objects surrounding an individual. Conceptual framework suggested in this
article allows holistically addressing the issues of commercial efficiency and socioeconomic management in the age of digitalization.
