摘 要: 本文以"五纵七横"国道主干线建设作为自然实验,实证研究了大型交通基础设施对沿线县域企业的影响方向和机制。结果发现,国道主干线会引致沿线县域企业生产资源向大城市集聚,并且集聚程度存在产业异质性,其原因在于不同生产要素对交通条件敏感度存在差异。尽管国道主干线促进了沿线县域企业专业化分工水平,但由于处于产业价值链低端,这些沿线县域企业难以与大城市企业竞争并分享来自分工深化的效率提升和经济利益。 The "five vertical and seven horizontal" national trunk system(NTS) is taken as a natural experiment to study the impact and mechanism of NTS on county-level enterprises along the system. It is found that the NTS has led to the accumulation of production resources of county-level enterprises along the system to large cities, and the degree of agglomeration has industrial-level heterogeneity. Although the NTS has promoted the specialized division of labor among county-level enterprises, it is difficult for these enterprises to compete with big-city enterprises and share efficiency and economic benefits from the deepening of labor division.
