摘要：The SME sector is exposed to an arduous and fierce competition to the disadvantage of enterprises that are actually non-competitive. Therefore, the problems of SMEs in developing countries are rich and complex. Algeria isn't immune to these difficult conditions; the SME is exposed to an open and intense environment. Public authorities have developed and have been implementing upgrade programs to promote the SME sector. Thus, the study seeks to find the key success factors of upgrade programs, and explores the dimension of adaptation of SMEs in developing and emerging countries, Algeria is a practical case. The study is theoretical. It aims to determine a theoretical model on the success factors of upgrade programs. The research operates a diverse literature review in emerging and developing countries. To explain this research, we will use the theory of resources dependency. While exploring the literature on upgrade programs in emerging and developing countries; our research was able to theoretically identify different success factors of the upgrade programs. In addition, research has managed to develop a theoretical model on the success factors of the upgrade programs.
