“三金”工程——金卡、金关、金桥,是国务院推进国民经济信息化的代表性工程,本期特以“三金”工程为专题,帮助读者了解“三金”工程,支持“三金”工程,参与“三金”工程。今天,计算机与通信为代表的信息技术所引起的社会生产力的跃进将不下于三百年前的蒸气机、本世纪初的电力。以至于一国经济发展的速度很大程度上取决于这种关键技术推广应用的程度。因此,在今天,信息技术的应用水平已成为国际竞争力的关键。必须承认,目前在信息技术的应用上,我们与发达国家还有很大的差距。美国的信息高速公路是多媒体通信进入家庭的高速公路,而我们现在的“三金”工程还只是字符通信进入企业的信息中级公路。但是,也应看到,由于我们的起点低,这样的公路也是一种跃进,它对于国 “Three gold ” project - Golden Card, Golden Gate, Golden Bridge, is the State Department to promote the national economy, a representative project of information technology, this issue special “three gold ” project as a topic to help readers understand “Project, support ” three gold “project, to participate in” three gold “project.
