The role of internal auditing on corporate governance: its effects of economic and environmental performance

Internal auditing has been an elementary and powerful component of corporate governance in business strategies. It is highly acknowledged as an important business control system in the realm of quality management. Business performance does not come by itself; it needs plenty of aids and capabilities. Existing studies have investigated the business performance with fewer outcomes in corporate sustainability, firm, and environmental performance. We present analysis and validated improvised hypothesis through structural equation modeling (SEM), using analysis of a moment structures (AMOS), on empirical evidence gathered from 304 Chief Executive Officer (CEOs) in Top Multinational Companies of Pakistan (TMCP). In this paper, we examine the role of internal audit functionality as an influencing factor via corporate governance in corporate sustainability, firm performance, and environmental performance. Moreover, business quality and performance are maintained using functions such as interests of shareholders, personnel and finance. Results suggest that internal audit functionality and corporate governance significantly influence corporate sustainability, firm performance, and environmental performance. Additionally, CEOs and top managers of TMCP are advised to concentrate on internal audit functionality with a mediating role of corporate governance that in turn encourages corporate sustainability, firm performance, and environmental performance.
