The economic importance of cross-sectional technologies: An input-output approach

Technologies that are used in different production processes of miscellaneous industries are known as cross-sectional technologies. The economic importance of these technologies normally is measured by economic benchmarks of the producing industry. However, the impact of these tech-nologies for the whole economy is often not exactly known. By using a modified input-output ap-proach, it is shown for the welding technology how much the economic importance of a cross-sectional technology exceeds the economic importance of the technology producing industry.
