This study investigates the motivating factors behind the formalization of small informal enterprises in Bangladesh, an emerging economy, employing the lens of institutional theory. It emphasizes how regulatory structures, normative pressures, and cognitive understandings shape the decisions of SME owners in emerging economies like Bangladesh. A significant portion of small enterprises in Bangladesh remain informal, leading to concerns over economic development, productivity, and efficiency. Informal enterprises often face challenges such as limited access to finance, market entry barriers, and regulatory hurdles. Recognizing the need for formalization, this research aims to understand the drivers behind this transition. A questionnaire survey of 304 informal enterprises reveals that streamlined regulatory systems, particularly one‐stop solutions and simplified registration processes, are primary motivators for formalization. Additionally, flexible collateral requirements for financing and lower levels of technological adoption also significantly influence this transition. These findings contribute to the academic discourse on informal businesses in emerging economies and provide key policy implications for fostering formalization through targeted strategies and policies.
