摘 要: 出口对于生产率的影响是经济学研究的重要论题之一。不同于以往研究,本文从企业异质性视野切入,实证考察了出口之生产率增长效应的非均衡性论题。借助新近兴起的技术前沿距离方法的研究表明,出口对于与技术前沿距离远的落后地区生产率提高的作用要大于与技术前沿距离近的先进地区,意味着出口具有Veblen-Gerschenkron效应,即技术落后地区在出口过程中获得的技术溢出和生产率增长要大于技术先进地区。而且出口的Veblen-Gerschenkron效应还具有时间持续性,随着时间的推移不断强化。针对门槛效应的检验表明,只有在行业出口超过某个临界值后,出口的Veblen-Gerschenkron效应才渐次显现并不断强化。此外研究还显示,新增长理论所强调的人力资本外部性和新经济地理学中的同行业集聚与关联行业协同集聚外部性都是影响生产率增长的重要因素。上述结论对于制定利用出口促进生产率增长的差异化地区政策具有重要的启示意义。 The impact of export on productivity is one of the important issues in economic studies. Different from previous research, this paper examines the imbalanced effect of export on productivity from the perspective of firm heterogeneity. By using the distance to the technological frontier method, the empirical results show that export fosters productivity growth in regions that are far from the frontier, suggesting a significant Veblen-Gerschenkron effect, which means that technologically backward areas benefit more in acquiring technology and economic growth when exporting than areas with advanced technologies and this imbalanced effect keeps a constant trend and is continuously reinforced over time. Considerations of the threshold effect show that the Veblen-Gerschenkron effect exists only when the export volume exceeds certain value. In addition, the study finds that human capital externality and agglomeration economies are positively related to the productivity growth. The above conclusions hold important reference significance when making differential regional policy to promote productivity growth by relying on export.
