Integrating Regulatory Capital into Knowledge Capital Measurement Model (KCMM) - Evidence from Ghanaian Service Firms

Abstract

The measurement of knowledge capital has become a cornerstone of organizational research, yet existing models typically emphasize human, structural, and relational capital without fully accounting for institutional and regulatory contexts. This study develops and validates a Knowledge Capital Measurement Model (KCMM) tailored to Ghanaian enterprises, extending the classical triad with a fourth dimension, regulatory capital. Drawing on the knowledge-based view of the firm and absorptive capacity theory, we collected survey data from 210 service-sector firms in Accra, encompassing telecommunications, banking, ICT, consulting, and logistics. Using confirmatory factor analysis (CFA) and structural equation modeling (SEM), we evaluated reliability, validity, and invariance across firm size and tenure.
The results demonstrate that the KCMM is psychometrically sound: Cronbach’s alpha and composite reliability exceeded 0.80 for all constructs, average variance extracted (AVE) values surpassed 0.50, and model fit indices were within recommended thresholds (χ²/df = 2.15; CFI = .943; RMSEA = .052; SRMR = .041). Regulatory capital emerged as a distinct and dominant construct, with the highest standardized loading onto the higher-order knowledge capital factor (β = .85, p < .001), surpassing human (β = .78), structural (β = .74), and relational (β = .69) capital. Multi-group analyses confirmed configural, metric, and scalar invariance across SMEs versus large firms and younger versus older organizations, with latent mean differences indicating stronger knowledge capital stocks among larger and more mature firms.
These findings extend intellectual capital theory by empirically validating regulatory capital as a fourth pillar of intangible assets in regulatory-intensive economies. They also highlight the contextual embeddedness of knowledge management: while relational capital dominates in global studies, Ghanaian firms prioritize compliance-driven knowledge as a strategic resource. Theoretically, this supports a contingent view of the knowledge-based firm, in which the salience of knowledge domains varies by institutional environment. For managers, the KCMM provides a validated instrument for diagnosing and balancing knowledge portfolios, while policymakers can design regulations as learning enablers rather than compliance burdens. Future research should test the KCMM longitudinally, incorporate objective performance indicators, and extend comparative analyses across African economies.
