Trends in innovation and productivity: The case of chemical and textile industries in the U.S.

This paper attempts to investigate an empirical linkage between technological innovation and productivity in two industries in the United States. During the period 1967—82, the chemical and textile industries experienced different rates of productivity growth. In spite of stiff competition from foreign manufacturers, American textile firms maintained a steady growth in productivity. This industry benefitted from major technological innovations occurring in industries supplying to it. The chemical industry faced crisis due to sudden changes in petroleum prices. Changes in regulatory requirements also imposed a different set of constraints on the chemical industry. Rate of innovation decreased quite severely in this industry during this time period.
Innovation indicators were developed by obtaining data on new product/process announcements in the technical literature. Panels of technical experts from the industries and academia evaluated the data for their technical novelty. The data indicate a relationship between innovation and productivity growth.
