第二次世界大战中 ,日本陆军的武器装备与美、苏、英等列强相比 ,一直存在着质差量小的问题。本文从日本的综合国力、军工生产和建军思想等方面探求其原因。指出 :日本经济孱弱、军费缺乏以及重海轻陆的军工建设实践 ,使陆军的兵器生产缺乏有力的物质和技术保证。同时日本建军思想中存在着浓厚的唯意志论倾向 ,也使日军军工生产的现代化受到阻碍。 In the Second World War, the Japanese army’s weapons and equipment, compared with the powers of the United States, the Soviet Union and Britain, have always had the problem of small qualitative difference. This article explores the reasons for Japan’s comprehensive national strength, military production and the idea of ​​army building. He pointed out: Japan’s weak economy, the lack of military spending and the heavy military construction in light of its land use have made the Army’s weapons production lacking strong material and technical guarantees. At the same time, there is a strong propensity for voluntarism in Japan’s military establishment and hinders the modernization of Japanese military production.
