This paper provides evidence about the relevant role of geography on spatial local networks in trade credit between industrial reduced size companies and distin- guishing the spatial behavior according to the firms’ size and technological intensity. Using data from a survey of small and medium companies in the municipality of Madrid (Spain), we find significant spatial effects in trade credit between spatially close industrial companies. Whereas prior work has examined the temporal dynamics in trade credit with aggregated information, the spatial dimension with firm level data has not been considered before in trade credit studies and is the aim of this study. We find significant results for the spatio-temporal networks between geographically close companies which cause interaction effects in the proposed models by concluding that firms’ surrounding local characteristics impact the issue of trade credit for each company.

本文提供了有关地理区域空间网络在减少工业规模的公司之间的贸易信用中的相关作用的证据，并根据企业的规模和技术强度区分了空间行为。使用来自马德里市（西班牙）中小型公司的调查数据，我们发现空间紧密的工业公司之间贸易信贷的显着空间效应。先前的工作已经研究了具有汇总信息的贸易信用的时间动态，而贸易信用研究之前并未考虑具有公司层面数据的空间维度，这是本研究的目的。
