市场分割是现阶段中国统一大市场建设的重要阻碍，也是影响企业-供应商分布距离的重要因素。文章利用2010-2023年中国上市公司数据，基于信息捕获视角考察了市场分割对企业-供应商分布距离的影响及其作用机制。研究结果发现：市场分割与企业-供应商分布距离之间呈现“倒U型”关系，即在市场分割程度较低的情况下，市场分割程度上升会扩大企业-供应商分布距离，但是当市场分割程度超过一定水平时，市场分割程度上升会缩短企业-供应商分布距离，且上述结论在经过一系列敏感性检验后依然成立。机制分析表明，市场分割分别通过影响企业、供应商两者信息捕获能力进而影响二者之间的分布距离；而且，市场分割对企业-供应商分布距离的影响在低信任水平地区、供应链依赖度低和非国有制的企业中更为显著。

Currently, market segmentation is an important obstacle to the construction of a unified national market in China. Besides, it is an important factor affecting the distribution distance between enterprises and suppliers. Using the data of Chinese listed companies from 2010 to 2023, this paper examines the influence of market segmentation on the enterprise-supplier distribution distance and its mechanism of action from the perspective of information capture. The results indicate that there exists an inverted U-shaped relationship between the market segmentation and enterprise-supplier distribution distance. Specifically, when the degree of market segmentation is lower than the threshold, an increase in the degree of market segmentation will expand the enterprise-supplier distribution distance; otherwise, it will shorten the enterprise-supplier distribution distance. The findings remain robust after a series of sensitivity tests. Mechanism analysis shows that market segmentation affects the distribution distance between enterprises and suppliers by influencing their information capture capabilities. Furthermore, market segmentation exerts a more pronounced influence on enterprise-supplier distribution distance for low-trust regions, enterprises with low supply chain dependence and non-state-owned enterprises.
