Measures of Innovation in Selected High-Technology Industries

这是一项研究的更新，旨在检查美国工业中产生的技术创新的数量和质量的趋势。生物技术和光波工程这两个特定领域的创新，将从数量和质量两方面进行研究。如果可能的话，这些创新趋势将与相关行业的生产率变化相关。该项目旨在提供美国在这些重要新技术方面的表现指标，并通过关注底层技术来增加对生产率趋势的理解。

This is a renewal of a study to examine trends in the number and quality of technological innovations produced in U.S. industry. Innovations in two specific fields, biotechnology and light-wave engineering, will be studied in terms of both their number and their quality. These innovation trends will be related if possible to productivity changes in the related industries. The project is intended to provide indicators of U.S. performance in these important new technologies and to add to the understanding of productivity trends by focusing on the underlying technologies.
