Seafood is the world’s most traded food product. In recent years, aquaculture has become an increasingly important part of seafood production, facilitating increased trade. However, despite evidence that fish farmers have better ability to target markets and ship their seafood through more efficient supply chains (due to the higher degree of control with the production process), little attention has been given to the fact that this is likely to influence trade patterns as well. This article investigates if trade margins for aquaculture products differ from trade in wild seafood products along three margins of trade, in addition to total export value on export data for Norway, the world’s second largest seafood exporting country. The results indicate aquaculture products are different. In particular, aquaculture products are influenced by more factors than fisheries products (such as transportation costs and per-unit shipment costs), highlighting another dimension where the control of the production process can be used to improve competitiveness. Moreover, exports of aquaculture products increase with a country’s wealth level, reflecting producers’ ability to target higher paying markets.

交付货物：挪威海产品出口的决定因素

海鲜是世界上交易量最大的食品。近年来，水产养殖已成为海产品生产中越来越重要的一部分，促进了贸易的增长。然而，尽管有证据表明养鱼者有更好的能力瞄准市场并通过更有效的供应链运输他们的海鲜（由于对生产过程的控制程度更高），但很少有人注意到这可能会影响贸易模式也是如此。除了世界第二大海产品出口国挪威的出口数据总出口值外，本文还调查了水产养殖产品的贸易利润与野生海产品贸易在三个贸易利润方面是否存在差异。结果表明水产养殖产品是不同的。特别是，与渔业产品相比，水产养殖产品受到更多因素的影响（例如运输成本和单位装运成本），这突出了另一个方面，可以利用生产过程的控制来提高竞争力。此外，水产养殖产品的出口随着国家财富水平的增加而增加，反映了生产者瞄准更高收入市场的能力。
