Purpose: Family businesses gain notoriety in academic research because they have peculiarities found only in this type of organization, and it is because of these attributes that this work aims to analyze, through an epistemological look, the results of a systematization that sought for works that use the unique characteristics of family businesses, called familiness, as well as two other constructs that showed attractive adherents and little researched in parities with familiness, organizational entrepreneurship, better known as entrepreneurial orientation and the ability to adapt, called absorption capacity. Design/methodology/approach: To achieve this goal, an investigation of national and international academic production was carried out through a systematization called Proknow-C, being possible to identify the main categorical groups of authors in the area, main journals, besides identifying and analyzing the main objectives and contributions of selected scientific articles. Findings: Among the results obtained, it was possible to consolidate some research intentions inherent to the junction of such constructs, besides directing, which can be the best and most promising fields of research for the application of these constructs and the most indicated methods, based on the three epistemological positions, subjectivism, objectivism and constructivism. Originality/value: This study adds value to the literature on familiness, pointing to a relationship between entrepreneurial orientation and absorption capacity, in contrast to studies focused on other dimensions of social capital, which obtained divergent results. In addition, this study reinforces the unique characteristics of family enterprises, in which this work intends to consolidate a methodological proposal with arguments linked to positivism or interpretativism in the midst of epistemology. The study provides a valuable theoretical framework of familiness determinants connecting the cognitive perspective of the entrepreneur theory to a view of the absorptive capacity.
