TECHNOLOGICAL CATCH‐UP AND GEOGRAPHIC PROXIMITY*
研究了企业生产率增长中追赶效应的作用，发现落后于行业前沿的企业生产率增长更快，且地理上靠近前沿企业会加速这一追赶过程。
ABSTRACT This paper examines productivity catch‐up as a source of establishment productivity growth. We present evidence that, other things equal, establishments further behind the industry frontier experience faster rates of productivity growth. Geographic proximity to frontier firms makes catch‐up faster. Our econometric specification implies a long‐run relationship between productivity levels, where nonfrontier establishments lie a steady‐state distance behind the frontier such that their rate of productivity growth including catch‐up equals productivity growth at the frontier. We use our econometric estimates to quantify the implied contribution to productivity growth of catch‐up to both the national and regional productivity frontiers.
