Analysis:

Compared with traditional industries, employees in high-tech industries have high-level knowledge and skills, among which scientists and engineers account for a large proportion, and item A is correct; Compared with traditional industries, high-tech industries grow faster, change greatly, the product renewal cycle is short, and item B is wrong; R&D expenses of high-tech industries account for a high proportion of sales, and item C is wrong; High-tech industrial products are not only for developed countries, but also for D.

Compared with traditional industries, the main features of high-tech industries are:

(1) among the employees, scientific and technological personnel account for a relatively large proportion; ② A large part of sales revenue is spent on research and development; (3) the product is updated quickly (two answers at three o'clock are enough).

The characteristics of high-tech industry are: rapid product upgrading; A large proportion of sales revenue is spent on research and development; High-tech industry is an industry with electronic information industry as the "leader", and its products have high scientific and technological content; Among the employees, scientific and technological personnel account for a large proportion.

High-tech industry is a collection of enterprises engaged in the research, development, production and technical services of one or more high-tech and its products based on high-tech. The key technologies owned by this industry are often difficult to develop, but once they are successfully developed, they have higher economic and social benefits than ordinary ones.

High-tech industries are knowledge-intensive and technology-intensive industries. The leading technology of the product must belong to the established high-tech field, and must include the technology or technological breakthrough in the high-tech field. According to this standard, high-tech industries mainly include information technology, biotechnology and new material technology.
