In recent decades, public management has been restructured worldwide for greater efficiency and innovation based on entrepreneurship-driven models such as Reinventing Governance, New Public Management, and post-NPM frameworks. The primary intent of these businesslike models is instilling entrepreneurship, which would encourage risk-taking innovation, managerial autonomy, performance orientation, and customer choice. Such entrepreneurial orientation is embedded in organizationalmanagerial reforms related to human resource management, budgeting framework, performance benchmarking, and so on. These entrepreneurship-driven reforms have significant impacts on administrative structure, procedures, and norms affecting the process of public sector accountability. In line with such global trends, most countries in Southeast Asia have embraced some of these pro-market business-type reforms in public management to enhance its entrepreneurship, innovation, and competition, which have implications for managerial control, neutrality, regulation, and integrity required for public accountability. This article explores these entrepreneurship-driven reforms in the region and evaluates their critical implications for the long-established institutions, structures, and procedures of public accountability.
