出口企业的空间集聚如何影响出口国内附加值

How Does the Spatial Agglomeration of Export Firms Affect Domestic Value Added in Exports

本文利用中国制造业企业数据,研究企业的空间集聚对出口国内附加值的影响。研究发现,企业空间集聚程度的提高有助于增加中国企业的出口国内附加值,其影响效应大小与企业参与贸易的方式、所有制性质、出口产品的技术复杂度以及出口目的地密切相关。加工贸易企业的出口国内附加值显著受到空间集聚的影响,但对一般贸易企业这一影响并不显著。产品技术复杂度越高,空间集聚对出口国内附加值的影响效应越大。本文研究表明空间集聚产生的中间品替代效应和资源再配置效应是提升出口国内附加值的重要渠道。

manufacturing firm-level data.The study finds that firms spatial agglomeration induces an increase in the DVAR among Chinese exporters,and the difference of magnitude of such impact is closely related to firms trade-type,ownership nature,technological sophistication and export destination characteristics. Positive effects are in particular more pronounced in processing,foreign-owned and more sophisticated firms than in ordinary,indigenous and less sophisticated firms.The mechanism analysis shows that the intermediate substitution effect of domestic for imported materials and the resource reallocation effect are two potentially significant channels through which spatial agglomeration increases the exporters DVAR.
