集群商业信用与出口产品质量——来自中国企业层面的证据

Clustering Trade Credit and Export Product Quality:Firm-level Evidence from China

提升出口产品质量是建设贸易强国的重要方面。本文基于中国工业企业数据库和海关数据库2000-2009年的合并数据,研究了城市集群商业信用对我国出口产品质量的影响。研究发现,集群商业信用对出口产品质量具有显著的正向影响,集中体现在促进私营企业和外资企业以及东部地区企业出口产品质量的提升上。具体机制是集群商业信用通过缓解企业融资约束促进了企业出口产品质量的提高。在控制集群企业数目和集聚程度后,结论保持稳健。一系列稳健性检验以及依据企业是否更换经营地点构造拟自然实验检验都证实了本文的基本结论。本文的研究结论是应重视集群商业信用等非正规融资在促进企业出口产品质量提升方面的关键作用。

Improving the quality of export products is an important aspect of building a strong trade country. Using combined data of China Industrial Enterprise Database and Customs Database from 2000 to 2009,this paper studied the impact of urban cluster trade credit on the quality of China' s export products. The study finds that cluster trade credit has a significant positive impact on the quality of export products,which is reflected in the promotion of the quality of export products of private enterprises and foreign-invested enterprises as well as enterprises in the eastern region. The specific mechanism is that cluster trade credit improves the quality of export products by alleviating corporate financing constraints. After controlling the number and concentration of clustering enterprises,the conclusions remain consistent. A series of robustness tests and place tests based on whether firms changed business locations confirmed the basic conclusions of this paper. The conclusions suggest that more attention should be paid to the key role of informal financing such as cluster trade credit in promoting the quality improvement of export products.
