Abstract Geographical concentration of industries tends to be important for firms that depend on innovation and are intensive in the use of specialized technology and labor. In this paper, we investigate the interaction between agglomeration and trade performance in the Norwegian aquaculture industry. We include a variable for regional clustering in a standard gravity model and estimate its impact on different margins of trade. When controlling for destination country, we find that firms that operate in clusters obtain higher export prices and ship more frequently and in smaller bulks. For a highly perishable product like fresh salmon, this may suggest that firms in clusters are served by more efficient supply chains bringing the product to market with timely and efficient logistics.

集聚和贸易表现——来自挪威鲑鱼养殖业的证据

摘要 产业的地理集中度对于依赖创新并密集使用专业技术和劳动力的公司来说往往很重要。在本文中，我们调查了挪威水产养殖业的集聚与贸易绩效之间的相互作用。我们在标准引力模型中包含了一个区域聚类变量，并估计了它对不同贸易利润率的影响。在控制目的地国家时，我们发现集群经营的公司获得更高的出口价格并且更频繁地以更小的批量运输。对于像新鲜鲑鱼这样的高度易腐烂的产品，这可能表明集群中的公司得到了更有效的供应链的服务，将产品通过及时有效的物流推向市场。
