摘　　要：本文从商业信用视角,基于中国分省分行业数据,考察了地理集聚对地区出口比较优势的影响。实证研究结果表明,在地理集聚程度高的地区,商业信用依赖度高的行业有更大的出口比较优势,这一结论不受内生性、不同度量指标及其它地区因素作用的影响。进一步分析地理集聚在出口比较优势作用上的地区差异性,发现与西部地区相比,东部地区的高地理集聚程度显著促进了商业信用依赖度高的行业出口,而中西部地区之间的差异较小。From the perspective of trade credit, using provincial and industrial da- ta, this paper examines the effects of geographical agglomeration on regional export comparative advantages. The results indicate that industries with higher dependence on trade credit exhibit greater export comparative advantages in high-degree agglomer- ation areas. Considering the endogeneity of geographical agglomeration and the influ- ence of other regional factors, and using different measures, the paper still proves the result robust. It is also found that there are significant regional differences on the ef- fects of geographical agglomeration on regional export comparative advantages. Com- pared with the western regions, high degrees of agglomeration in eastern regions sig- nificantly promote exports of industries with higher dependence on trade credit, and the difference between middle regions and west regions is small.
