Co-location of skill-related suppliers: advancing coagglomeration research using firm-to-firm network data
研究了供应链伙伴在交换商品的同时也交换知识时更可能共定位的现象，利用匈牙利微观数据验证了集聚渠道的超加性，发现供应链主要促进技能相关行业的企业共定位。
Abstract Firms in industry clusters benefit from locating close to suppliers and customers. However, the pervasiveness of global value chains questions the need for co-location in buyer–supplier relationships. We propose that supply-chain partners are more likely to co-locate if they exchange not only goods but also know-how, implying superadditivity of Marshallian agglomeration channels. We test this in a coagglomeration framework using microdata for Hungary—a small, open economy deeply embedded in global value chains—examining co-location, labor flows, and value chains between firms and industries. We find that supply chains foster co-location primarily among firms in skill-related industries.
