国内市场一体化与企业出口行为——基于市场可达性视角的研究

Domestic Market Integration and Firm Export Behavior——A Research Based on Market Access Approach

本文通过构建市场可达性指标,研究了交通基础设施建设带来的国内市场一体化对企业出口行为的影响。研究发现,国内市场一体化会显著提升企业的出口概率和出口额,原因是市场一体化降低了企业所在行业的临界出口生产率水平,并促进了既有出口产品的出口市场扩张。对于生产率高的企业、初始具有比较优势的行业,交通基础设施扩张的出口促进作用更大,表明国内市场一体化对于具有发展能力和潜力的企业和行业具有更大的促进效果。

In this paper we build a market access indicator to study the effect of domestic market integration induced by transportation infrastructure on firms’ export behavior. We find that the increase of market access significantly promotes firms’ export probability and export volume. This effect mainly comes from the reduction of the productivity cutoff of exporting firms, and the increase of export volume of incumbent products rather than new products. Further heterogeneous exercises show that for firms with higher productivity, industries with comparative advantage, the promotion effect of the increase of market access on firms’ export is stronger.
