Abstract According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up a cost-benefit analysis of salmon farming as seen from a municipal perspective. On the benefit side, we count consumer and producer surplus of increased aquaculture production in the region and the region’s share of the national rent in aquaculture received as transfers from the national Aquaculture Fund. Costs are the opportunity cost of the land (sea) use, measured by households’ willingness to pay to avoid aquaculture expansion, using data from a choice experiment. We find that parts of the producer surplus have to contribute to the regional economy for the NPV to be positive for a region.

挪威北极地区水产养殖扩张的成本效益分析

摘要 根据政府计划，挪威面临养殖大西洋鲑鱼产量的巨大扩张。然而，指定沿海地区从事水产养殖活动的是市政当局，他们的动机取决于市政一级从这种使用中获得的净收益。然而，关于利用沿海地区进行水产养殖活动的成本和收益的经验证据很少。我们从市政角度对鲑鱼养殖进行了成本效益分析。在收益方面，我们计算了该地区水产养殖产量增加的消费者和生产者盈余，以及该地区作为国家水产养殖基金转移收到的水产养殖国家租金的份额。成本是土地（海洋）使用的机会成本，以家庭为避免水产养殖扩张而支付的意愿来衡量，使用来自选择实验的数据。我们发现部分生产者盈余必须对区域经济做出贡献，NPV 才能为区域带来正值。
