This study sought to investigate the impact of entrepreneurial orientation (EO) and entrepreneurial bricolage (EB) on frugal innovation (FI), and subsequently, the sustainable performance of small and medium-sized enterprises (SMEs) in emerging markets (EMs). Data were collected from 750 key decision-makers in manufacturing small and medium-sized enterprises (SMEs) in the cities of Dar es Salaam and Arusha, Tanzania, yielding a response rate of 51.47%. The data was analyzed using structural equation modeling in SmartPLS software. The results revealed that EO had a positive and significant effect on both FI and EB.
