For several years now, economic and social crises have led the people of Benin to find survival solutions. For the most part, these players have settled in the informal sector. Through the businesses they have created, they contribute to local development. That's why we chose this topic, whose aim is to study the socio-economic functions of entrepreneurship in the local development process, and hence all the dynamics surrounding business realities. Thanks to the methodology, techniques and tools we have developed, we have arrived at the following results: entrepreneurship is a real field that offers various development opportunities, both economically and socially; the development of businesses increases hiring and consequently improves the flow of migration. It's also worth noting the forms of social organization, policies and mentalities that emerge thanks to business start-ups. However, this area remains to be explored for greater viability and credibility in order to create stable, lasting jobs.
