Other than serving as the introduction to this special issue, this paper looks at the question of how an underdeveloped or a developing economic entity can manage to acquire the knowledge and ability to overcome various barriers, be they social, cultural, or institutional, to establish its desired momentum of self-sustained growth. It addresses the question by surveying relevant literatures, first, about what factors, both internal and external, positively determine the innovativeness of an economic entity; and second, regarding what steps are necessary for an underdeveloped or a developing entity to engineer its momentum of self-sustained growth and for an established entity to maintain its existing momentum. By doing so, we demonstrate the theoretical significance and practical importance of this issue and the works contained in this issue.
