Purpose This study aims to fill three theoretical gaps in previous literature on exploration and exploitation: the relationship between exploration and exploitation is inconclusive; the influences of exploration and exploitation on firm performance are not consistent; and no empirical studies have integrated the antecedents of exploration and exploitation from the different research fields. Design/methodology/approach The study conducted a meta-analysis to quantitatively synthesize 143 studies with 257 independent samples to understand the relationship between exploration and exploitation and their consequences and antecedents. Findings The results show that exploration and exploitation are positively correlated with each other, and both of them can boost firm performance. Moreover, firm capabilities, firm size, firm age, competitive intensity, market orientation and entrepreneurial orientation positively influence exploration, and firm resources, firm capabilities, firm size, firm age, market orientation and entrepreneurial orientation positively influence exploitation. Competitive intensity negatively influences exploitation. Surprisingly, market turbulence does not significantly influence exploration or exploitation. Originality/value The results not only contribute to the theories by reconciling the inconsistent results but also provide insight for firms with guidance about under what conditions they should use what strategies.
