在拙作《初论北亚诸文化圈与北亚草原丝道》一文中,作者已基本解决了商周时期中西贸易的路线、内涵等问题。在本文中,作者想就前文所未能展开讨论的问题再做一番议论,故曰“再论”。经研究,笔者发现,早在商周时期,中西方间确已存在着商业间的往来。这种往来基于两个基本条件:其一,东西方社会经济的发展;其二,东方、西方、沿途诸文化圈的形成。经研究,作者还发现,商周时期的中西商业活动,不但活跃了东西方的社会经济,而且还刺激了沿途社会经济的发展。 In his essay “First on the Beauties of North Asian Cultures and the North Asian Grassland,” the author has basically solved the problems of the lines and connotations of the Sino-Western trade during the Shang and Zhou dynasties. In this article, the author would like to discuss some of the issues previously failed to do some talk about it, so saying “re-discussion.” After research, I found that as early as the Shang and Zhou dynasties, there was indeed a trade between China and the West. Such exchanges are based on two basic conditions: first, the development of socio-economic development in the East and the West; and second, the formation of cultural circles along the East, West and the West. After studying, the author also found that the commercial activities between China and the West during the Shang and Zhou Dynasties not only stimulated the socio-economic development of East and West, but also stimulated the social and economic development along the route.
