Abstract In recent years, European producers of cultured sea bass and sea bream have experienced a highly competitive market with low prices that have caused profitability challenges. An important factor of economic competitiveness for firms is to produce efficiently. In this paper, technical efficiency of European producers of cultured sea bass and sea bream is evaluated for the period 2008–2017 using the stochastic production frontier (SPF) approach. In addition, the effect of a set of specific-firm factors on firms’ efficiency is investigated. The majority of firms in the sample were found to have a technical efficiency over 90% with Cypriot and Greek firms being, on average, the most efficient. We also found evidence that the technical efficiency of these firms is positively related to their size. Moreover, the high degree of average efficiency means that further production growth requires innovations that move up the production frontier.

欧洲公司在地中海养殖鲈鱼和鲷鱼的技术效率：随机生产前沿 (SPF) 方法

摘要 近年来，欧洲养殖鲈鱼和鲷鱼生产商经历了市场竞争激烈，价格低廉，盈利能力面临挑战。企业经济竞争力的一个重要因素是高效生产。在本文中，使用随机生产前沿 (SPF) 方法评估了 2008-2017 年期间欧洲养殖鲈鱼和鲷鱼生产商的技术效率。此外，还研究了一组特定企业因素对企业效率的影响。发现样本中的大多数公司的技术效率超过 90%，平均而言，塞浦路斯和希腊公司的效率最高。我们还发现证据表明这些公司的技术效率与其规模正相关。而且，
