随着引进项目的增加,为了维持生产,进口配件和原材料也愈多。据机械系统不完全统计,引进技术中材料国产化程度不到50％,重点骨干企业每年需进口钢材48万吨,价值4～5亿美元。因此,加快引进技术中材料国产化是一项十分紧迫的任务。 引进技术国产化程度,最终应以零配件及所用材料的国产化程度来衡量。因此,材 With the increase in the number of imported projects, the number of imported parts and raw materials will also increase in order to maintain production. According to the incomplete statistics of the mechanical system, the localization degree of imported materials is less than 50%, and key enterprises need to import 480,000 tons of steel every year, valued at 400-500 million US dollars. Therefore, accelerating the localization of materials in the imported technology is a very urgent task. The degree of localization of imported technology should ultimately be measured by the degree of localization of spare parts and materials used. Therefore, wood
