A technology index based on R&D, skilled labour and capital vintage was developed and used to characterise industrial firms by technology level, facilitating the analysis of relationships between technology and economic performance at the firm level. The results show that technology-intensive firms are important players in industrial performance, accounting for a disproportionate share of total production. Compared to other kinds of firms, technology intensive firms are larger, more productive, offer higher average salaries, generate a higher value added and a highcr profit per employee and capital. They also tend to operate in more highly concentrated industries and are more involved in external trade. While down-sized as a group, high-tech firms show net job creation during the 11-year period surveyed.
