1.国家或民族在世界上的政治、经济地位是决定其图书外向型程度的外部条件。1978年前,中国出口的图书很少,版权贸易几近于零。随着我国改革开放不断深化,我国图书的外销和版权转让等,也步入了一个新的台阶。仅就1992年第四届北京国际图书博览会为例,一次达成合作出版就有500多项,加上全年其它时间签署的协议,数字相当可观。 1. The political and economic status of a nation or nation in the world is the external condition that determines the degree of extroversion of its books. Before 1978, China exported very few books and copyright trade was almost zero. With the continuous deepening of China’s reform and opening up, China’s book export and copyright transfer, etc., have also entered a new level. As for the Fourth Beijing International Book Fair in 1992, for example, there were over 500 cooperation and publishing agreements at one time, and the number of agreements signed at other times of the year was quite impressive.
