Entry, Innovation and Productivity Growth
利用1976-79年英国79个行业的数据，发现进入和创新活动对全要素生产率增长有显著且持久的影响，其中创新活动的影响大于国内进入，而外国进入影响不大。
This paper examines the effect of entry and innovative activity on total factor productivity growth. Using a sample of seventy-nine industries in the United Kingdom, 1976-79, significant effects are observed that persist over time, with innovative activity accounting for a larger positive effect on total factor productivity growth than domestic entry. Foreign entry has little apparent effect on productivity growth. Copyright 1989 by MIT Press.
