The ongoing evolution of both the theory and practice of value co-creation has made investigating its antecedents and consequences a central focus within academic discourse. Nevertheless, extant literature reveals notable disparities in empirical findings. Consequently, a comprehensive meta-analysis was undertaken, encompassing 461 effect sizes derived from 139 studies and 141 independent samples. The primary objective was to synthesize and delineate the antecedents and ramifications that shape value co-creation. The analysis reveals that significant antecedents influencing value co-creation among stakeholders encompass 14 variables spanning four dimensions: enterprise characteristics, customer attributes, interaction modalities, and environmental factors. Concerning enterprise characteristics, the influence of corporate capital on value co-creation demonstrates a robust correlation, whereas the impact of technological innovation capability within enterprises on inter-stakeholder value co-creation is found to be nonsignificant. Across various dimensions of customer attributes, factors exhibites a high degree of correlation with value co-creation. Moreover, the study identifies a strong correlation between the convenience of inter-stakeholder interactions and value co-creation within interaction modalities. Furthermore, in examining the consequences of value co-creation, a significant correlation is observed with all outcome variables. More broadly applicable research insights are presented, thereby laying a robust groundwork for further comprehensive investigations into value co-creation.
