Previous research in the literature often investigated the associations between management accounting systems and the success of organizations. However, little has been done in regard to the association of business strategies, goals, and firms’ performance while having management accounting tools as mediators. Management accounting systems are classified as traditional and strategic management accounting themes. Each theme, of course, implements different accounting tools. This article explores the degree to which, as mediated by management accounting systems, the business strategies and business goals of large Thai manufacturing companies influence their financial and non-financial performance. To gather the data, a survey questionnaire was developed. Of the 1500 companies selected for inclusion in the survey, 205 provided completed and usable responses for a response rate of 13.67%. Structural equation modeling (SEM) was used to analyze the relationships among the variables. The findings shed some light on what the management of a firm could expect concerning organizational performance from their business strategies, business goals, and the implementation of specific management accounting systems. Corporate strategies and corporate goals had a statistical influence on both the financial and non-financial performance of the large corporations in Thailand when mediated via strategic management accounting systems, while there was no influence when mediated by traditional management accounting systems. A greater understanding of the relationships and effects of which mediators should have been employed in organizations to bring forth business strategies and business goals and generate productive results for organizational performance is provided by this research. Choosing the appropriate performance mediators can help achieve corporate strategies and goals.

This study examines whether audit quality enhances the value relevance of earnings and book value of equity in explaining market prices of common shares in Thailand’s emerging market. Using data from 401 non-financial firms listed on the Stock Exchange of Thailand between 2021 and 2023, we analyze 1203 firm-year observations collected from Bloomberg and company annual reports. Multiple regression results show that earnings per share (EPS), book value per share (BVPS), and audit quality measures are significantly associated with share prices. Audit quality is proxied by audit firm size, audit fees, and financial statement irregularities (Beneish M-score). Big 4 auditors increase the relevance of book value, while higher audit fees strengthen the earnings–price relationship. Conversely, firms with higher M-scores, signaling potential earnings manipulation, display weakened associations between accounting metrics and share value. These findings highlight audit quality’s role in reducing information asymmetry, reinforcing investor trust, and supporting market efficiency in a post-crisis environment. By integrating audit quality into the Ohlson valuation framework, this study contributes to the literature on audit assurance and capital market behavior in emerging economies, offering insights for investors, regulators, and managers regarding the credibility of financial reporting.
