A retrospective of the current economic situation in Niger shows that the establishment of large companies in Niger has hardly seen a significant increase and that the Nigerian state remains the only source of employment. The few companies that are created hardly have a long lifespan due to multiple and multiform constraints; hence the problem of sustainable management of small and medium-sized enterprises (SMEs) in Niger. However, the rate of firms setting up and continuing their activities over the long term remains a major concern for the State and public authorities. It should be noted that the concept of entrepreneurship is the subject of a rather marked revival of interest on the part of researchers from different disciplines. It also appears that various economic, social, ideological, political, industrial and historical factors contribute to the existence of public, para-public and private companies. The aim of this contribution will be to highlight the factors that hinder the unsustainability of these small and medium-sized enterprises (SMEs) in Niger and to find strategies that allow them to be properly managed based on field data analyses.
