High-tech and Others

Abstract

High-tech is a kind of frontier science & technology which is based on comprehensive scientific research. It can bring about huge economic and social benefit. Nevertheless, it is a relative concept which has different meanings at different time, in different countries, or in different fields. Modern science and technology develop so fast that high-tech of today may no longer be high-tech tomorrow. In the 1950s transistor computers belonged to high-tech fields, integrated circuit computers take their place today, but tomorrow it may be replaced by optical integrated computers. A traditional technique in developed countries may still belong to high-tech fields in developing countries, e.g. automobile, aircraft manufacturing and so on. Therefore, different countries have different understanding of high-tech. A national high-tech roadmap should be made according to the scientific and technological level, the industrial manufacture level and economical level of the country.
