摘要：
We examine data from the PC software industry to determine if new forms play an important role in the advance of technology in this industry over the period 1982-1987. We find that new firms have a comparative advantage (over established firms) in creating new software categories, while established firms have a comparative advantage in developing subsequent improvements in existing categories. © 1991.
