文化在时间和空间的维度上是流动的,文化必须以占有时间和空间为前提:以广阔的空间兼收并蓄,以充裕的时间让其积累沉淀。经济和文化是互动的,文化对经济也有反作用,表现为经济的文化化和文化的经济化。汉语言文字不仅是文化流动的镜像,也是文化流动的桥梁,而移民文化是文化流动理论的最好注脚。 Culture is flowing in the dimension of time and space. Culture must take the time and space as its preconditions: it should be accumulated in a vast space and accumulate in ample time. Economy and culture are interactive. Culture also has an adverse effect on the economy, manifested in economic and cultural economy. Chinese language is not only a mirror of cultural flow but also a bridge of cultural flow, while immigrant culture is the best footnote of cultural flow theory.
