Competing at Home to Win Abroad: Evidence from Japanese Industry
利用日本产业数据，用市场份额波动衡量国内竞争，发现国内竞争越激烈，产业的世界出口份额越高，尤其在研发强度高的行业；贸易保护则削弱出口表现。
The study explores the influence of domestic competition on international trade performance, using data from a broad sample of Japanese industries. Domestic rivalry is measured directly using marketshare instability rather than employing structural variables such as seller concentration. We find robust evidence that domestic rivalry has a positive and significant relationship with trade performance measured by world export share, particularly when R&D intensity reveals opportunities for dynamic improvement and innovation. Conversely, trade protection reduces export performance. These findings support the view that local competition - not monopoly, collusion, or a sheltered home market - pressures dynamic improvement that leads to international competitiveness. © 2001 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
