Abstract

This research article aims to: (1) examine the direct and indirect effects of work competency, transformational leadership, and information technology on the performance of consulting service businesses of accounting and law firms in the Andaman Coast provinces through competitive advantage; (2) analyze the relationships among work competency, transformational leadership, information technology, and competitive advantage influencing the performance of consulting service businesses of accounting and law firms in the Andaman Coast provinces; and (3) develop a causal model of competitive advantage affecting business performance and branch expansion of accounting and law firms in the Andaman Coast provinces of Southern Thailand. The sample consisted of 402 executives or managers of accounting firms and law offices registered with the Federation of Accounting Professions under the Royal Patronage and the Lawyers Council under the Royal Patronage. A mixed-methods research design was employed. The statistical techniques included frequency, percentage, mean, standard deviation, and structural equation modeling (SEM). The findings revealed that: (1) the overall level of importance was high (ð‘ĨĖ… = 4.38, S.D. = 0.63); (2) the model fit indices were acceptable (χÂē/df = 1.169, CFI = 0.999, GFI = 0.982, AGFI = 0.962, RMSEA = 0.021, and SRMR = 0.002); and (3) the proposed model demonstrated a good fit with empirical data. Information technology facilitates customer database management, while personnel expertise has a direct effect on customer trust. The practical implications suggest that business owners who understand local contexts and legal environments, together with the effective application of technology in service delivery, can enhance competitive advantage and improve business performance.
