Abstract
Digital transformation is central to customs modernization, yet empirical evidence on how regulatory digitization translates into employees’ job proficiency through capability-building remains limited in Peru. This study aims to test the relationships among digital customs regulations, digital transformation, professional competencies, and job proficiency in Peruvian customs agencies, including the mediating role of professional competencies, using PLS-SEM. A quantitative explanatory–predictive, cross-sectional design was applied. Data were collected via a five-point online survey of 104 employees in Peruvian customs agencies (Lima–Callao) in October–November 2025, recruited through WhatsApp-based convenience/snowball sampling. The model was estimated in ADANCO 2.4.1 with a two-stage approach for the higher-order digital transformation construct and bootstrap inference. Digital customs regulations strongly predicted digital transformation (β = 0.872, p < 0.001) and generated a sizeable total indirect effect on job proficiency (β = 0.757, p < 0.001). Digital transformation increased professional competencies (β = 0.853, p < 0.001) and had a direct effect on job proficiency (β = 0.464, p = 0.026), while professional competencies also enhanced job proficiency (β = 0.473, p = 0.023). Mediation was supported for the pathway digital transformation → competencies → job proficiency (β_ind = 0.403, p = 0.034), yielding a total digital transformation effect of β = 0.867. Explanatory power was high (R²: DT = 0.761; competencies = 0.725; job proficiency = 0.814; SRMR = 0.041). The findings indicate that regulatory-driven digitization improves work proficiency primarily when accompanied by systematic competency development, highlighting training and institutional enablers as priorities in customs reform.
