摘要
本文分析了中国1998-2007年间大规模建设的国道主干线对出口的影响,我们基于地理特征构建施工成本最低的公路网络,以此作为实际公路路线的工具变量,解决了内生性问题。研究结果表明,1998-2008年与国道主干线连接的地区、与国道主干线距离近的地区有更高的出口额增长率。我们估算了1998和2008年各地区到重要港口的交通成本,发现交通成本下降越多的地区,出口额增长率越高。进一步分析表明,以上效应具有异质性:出口产品的重量价值比越高的地区,受国道主干线影响越大;地势崎岖的地区,受国道主干线影响较小。
This paper investigates the impact of China＇s National Trunk Highway System on export. To address endogeneity concerns, we calculate the least-cost network connecting all the targeted cities based on geographic characteristics. The estimation results suggest that counties that were connected to the highways and that were close to the highways experienced more rapid export growth during 1998-2008. In addition, if the counties＇ trade costs to seaports declined more, then their exports grew faster. These effects are more significant for counties exporting goods with higher weight-value ratio, and are less significant for counties with more rugged terrains.
