It’s difficult to use foreign language specially Chinese to write about some new concepts like Islamic economic thought in Mauritania and Other Muslim world. But it’s Important to introduce a great idea about your country and religion to others. So The present Thesis examines and evaluates research experiences in the area of the history of Islamic economic thought during the last 30 years in Mauritania and around the world with the objective to come across an idea about this science and it’s role to resolve most of modern economics problems in the world, and to see the pace of research and its coverage, both author-wise and idea-wise, and to determine the future research agenda in the light of the past progress and trends of the literature. The Thesis begins with a brief presentation of Mauritania Economics and a brief survey of the early literature on the history of Islamic economic thought, prior to 30-years, to provide a background. Then it studies and evaluates the research during the last thirty years,. It finds that hitherto the research in the history of Islamic economic thought has been language, region and period specific-Arabic, the Middle East and up to 9th/15th century respectively. More attention has been paid to write on economic thought of few personalities than others. The situation is still worse in case of idea-wise research. However, this literature has exerted some effects on scholars of the main stream economic thought and a few of them are trying to rehabilitate it in the main body of economic thought. At the end, the Thesis emphasizes on need for intensive and extensive research to include more personalities, ideas, periods, languages and regions and to write a systematic history of the subject. Research on history of Islamic economic thought during the last thirty years has enriched the discipline with tremendous literature. Writings in this period are characterized by rigorous analysis and professional skills. They provide materials that may be used to make up existing deficiency-the great gap-in the literature on the history of economic thought. It should benefit Western economists as well, who admit on their part the existence of a great gap between ancient Greek thought and scholastic economic thought but are unable to explain it. These works show that Islamic economic thought and the role played by Muslim scholars and its place in development of mainstream economics are increasingly attracting the attention of scholars and researchers.
