摘要：In the creation of a new nomenclature for economic systems theory, Nicklas Luhmannʼs
sociological conceptualism may sometimes perform a heuristic role. In particular, the concepts
of ʻautopoiesis systemʼ and ʻobservation of observationsʼ can be extremely useful for the
analysis of a far-reaching constellation of various economic concepts.
This study develops the elementary terminology of metaeconomics and economic systems
theory, and emphasizes the significance of the ʻobservation of observationsʼ. In most cases when
several fundamental concepts need to be logically constructed, the corresponding mathematical
symbols and notions may often be utilized as the means for representing their formal functions.
Amongst others, ʻcategoryʼ is the most important, because it can formalize the structure of
economic systems and meta-observations from the viewpoint of logical foundations.
