4.3.2Variables at the Industry Level

This section describes data on output, capital and hours at the aggregate industry level. Table 4.7 describes the average values for each variable between 1977 and 1997. Not surprisingly, the top 10 most IT intensive industries (highest IT ratio) belong to the service sector, except for the “Electronic, instruments and related equipment” manufacturing industry. In these 10 industries, the IT capital stock represents more than 15% of the total capital stock. This ratio is highest for the “Communications” industry, where almost half of the total capital stock is IT capital.
