The objectives of this study were to 1) examine the impact of strategic management accounting (SMA) that influences business sustainability by integrating comprehensive internal information and external business environment to formulate strategic decision-making to enhance competitiveness, and 2) investigate the serial mediating role of business strategies and competitive advantages. Data were collected from a total of 168 samples of listed companies in the Stock Exchange of Thailand and analyzed by using partial least squares structural equation model. The results showed that strategic management accounting had a positive direct impact on innovation-oriented strategy, efficiency-oriented strategy, and sustainable performance. Innovation-oriented strategy and competitiveness was found to have serial mediating effect on strategic management accounting and performance sustainability. However, both efficiency-oriented strategy and competitiveness had no serial mediating effect on strategic management accounting and sustainable performance. The implications in this present study confirm that strategic management accounting plays a significant role in determining effective business strategies; therefore, executives need to focus on related resources to foster the strategic management accounting which in turn enhances the firm’s competitiveness and sustainable performance.

This paper aims to investigate the factors of competitive success and examine the relationship between Strategic Management Accounting, management accounting information systems and sustainability performance. This research was conducted with a quantitative approach. The survey involved 125 managers of 4- and 5-star hotels in Bali, Indonesia, a research sample of 154 managers was determined to be given a research questionnaire. Analysis of research data was carried out through Structural Equation Modeling. The results showed that strategic management accounting and Information Management Accounting System had a positive effect on sustainability performance. MAS information also mediates the relationship between strategic management accounting and sustainability performance which can involve a variety of factors. This study only focuses on competitive strategy and MAS information variables, so further research is needed on the sustainability performance of the hospitality industry. The positive relationship between strategic management accounting and social and environmental performance supports the argument that hotels use socio-environmental aspects for their strategic management accounting. Hotel managers also need government regulations and information related to social and environmental issues such as the Indonesian occupational health and safety management system and the Indonesia Green Hotel Award.
