Integrative Theory of Diversification: Reconciling Conflicting Performance Outcomes through Contingency and Agency Lenses

Existing studies (e.g., Li, 2024; Zhan et al., 2025; Barker et al., 2024) reveal conflicting findings about the effects of diversification on firm success. Rather than treating these contradictions as anomalies, this idea proposes an integrative model that explicitly accounts for contextual moderators: governance structures, industry dynamism, market maturity, and CEO characteristics (as discussed in Inneh et al., 2025). By empirically testing how these variables interact to produce positive or negative diversification outcomes, the research could generate a more nuanced, predictive theory of diversification’s true impact—offering much-needed clarity in a muddled field.
