Abstract: In the last two decades, there is a micro-level tendency in the academia of strategic management. The studies focused on the individual, and tried to discover the relation between individual behavior as well as outcome and meso-level as well as macro-level issues. Some scholars argue that there are well-known theories and models at the macro level in the studies of strategic alliance, but the details inside the alliance still are not clear. This implies that it is necessary to involve deeper level, such as micro level, to improve the studies and theories. This study illustrates the tendency of micro-level study in the domain of strategy management during the last two decades, concludes the core and significance of micro-level study; combing with the uniqueness and the micro foundation of concepts about strategic alliance, the study argues the necessity and feasibility of the micro-level study on strategic alliance; finally it suggests the possible problems and directions of the micro-level study.
