1949年,在日本通产省发表的《技术白皮书》中,政府承认:与当时欧美的工业技术水平相比,日本的差距达10至30年。然而四十年后的1989年,在美国获得技术专利件数前三名的却都是日本企业,而在前十名中,日本企业竟占了5家!“二战”后美、日两国科技实力差距的急剧缩小,原因是多方面的,本文仅从国家科技政策的角度做些探索。 In 1949, in a “technical white paper” published by Japan’s MITI, the government admitted that Japan had a 10 to 30 year gap compared to the level of industrial technology in Europe and the United States at that time. However, four years later, in 1989, the top three patents in the United States were Japanese companies, while in the top ten Japanese companies accounted for only five. After World War Two, the technology between the United States and Japan The sharp decline in the strength gap, for many reasons, this article only from the perspective of national science and technology policy to do something to explore.
