Plant Age and Technology use in U.S. Manufacturing Industries
利用1988年美国制造业技术调查数据，描述先进技术使用如何随工厂年龄和规模变化，发现新旧工厂使用频率相近，但大工厂更可能采用新技术。
In this article, I use a new dataset on advanced technology usage in U.S. manufacturing plants to describe how technology use varies by plant age and size. The data come from the 1988 Survey of Manufacturing Technology (SMT) and cover a wide range of technologies and a large group of fabrication and assembly industries. Both old and young plants appear to use advanced manufacturing technology at similar frequencies. As in previous studies, I find that larger plants are more likely to employ newer technologies than are smaller plants.
