文摘Different regional cultures in modern China have their own characteristics while sharing some commonness,due to regional traits as well as common routes for development.Shanxi merchants’culture,as a typical representative of Chinese regional culture,reflects Chinese spirits,such as hard work,innovation and honesty and so on from the history of its development,change and cultural connotation,which reveals its macro commonness and micro characteristics.The essence of Shanxi merchants’culture can promote China’s economic development as the excellence of Chinese culture.
