传统的中国士人一向以“清高”自命，他们热衷于仕途，而不屑于商务。但由于种种原因，士人经商者代有所见。本文以唐宋时期整个社会变革为背景，全面考察了此时期的“士人经商”现象。分析了唐前期“士人经商”稀缺的原因及唐宋之际“士人经商”的两个变化趋势，并对此时期士人经商的原因及最终归宿作了论述。 Traditional Chinese scholars have always been “noble” self-proclaimed, they are keen on career, and disdain in business. However, for various reasons, scholars have been seen doing business. Based on the whole social change in the Tang and Song Dynasties, this paper comprehensively examines the phenomenon of “businesspeople doing business” during this period. This paper analyzes the reasons for the scarcity of “scholars’ business” in the early Tang Dynasty and the two changing trends of “businesspeople” during the Tang and Song dynasties. It also discusses the reason and eventual return of the scholars during this period.
