Based on the subjective approach to economic research, the author presents a comparative analysis of the nature of market and non-market economic relations. While market relations are essentially cost-based materialized relations, realized through spontaneous mechanisms, non-market relations are based on person-to-person relations. These relations are based on mutual personal interactions among people as economic subjects and involve their subjectivities and volition.

The author discusses the role of infrastructural projects in the formation of the New Eurasian wave in the XXI c.
