The aim of this study was to investigate the theories and research topics that guided the micro-foundations of the strategic management discipline between the years 2000-2020 and to make suggestions about the future of micro-foundations research. In the study, 122 articles were analyzed by the structured literature review method. In the research, qualitative content analyses were used and an inductive analysis was performed. As a result of the analyses, theories were classified based on the disciplines. In research topics, sub-categories were determined by bringing together the similar topics. Then, research topics are coded from subcategories to basic categories. The findings indicated that the micro-foundations of strategic management were dominated by behavioral theory of the firm, evolutionary theories of economic change and Coleman's social theory between the years 2000-2010. In addition to these three theories, the effects of actor-social network theories, theory of practice, behavioral decision theory, goal framing theory, organizational learning theory, upper echelon theory and transactive memory system were present between the years 2011-2020. According to the findings, variables such as cognition, motivation, human resources management, human capital, managers and individual variables were investigated in the micro-foundations of macro-strategic phenomena at the levels of capabilities, organization and network between the years 2000-2010. Between the years 2011-2020, macro-phenomena such as context, acquisition and mergers were also included in micro-foundations research, in addition to macro-strategic phenomena in the previous period. The topics such as psychology and entrepreneurship were included within the scope of micro-phenomena discussed in the studies in the previous period between the years 2011-2020.
