这项工作的目的是衡量冰岛捕捞公司和港口配额持有量集中的发展情况。在1990年至2014年期间，该分析追踪了经营大型船舶的最大行为者以及雇用仅允许使用钩绳的小型船舶的公司的相对配额持有量的发展。一个更详细的数据集用于2001 - 2014年期间，允许更彻底的调查合并在两个舰队部分使用赫芬达尔-赫奇曼指数，基尼系数和洛伦兹曲线。在此期间，这两个船队中最大的公司增加了配额份额，但配额市场仍然竞争激烈。各公司之间的配额分配变得更加不平等，而且有明显的证据表明，港口之间的转让越来越多，特别是在钩钓船的配额份额方面。然而，研究结果也表明，在所考虑的时期内，空间集中度远低于公司层面的整合度。这将表明，公司的规模大多是通过与当地公司合并或收购当地较小的运营商而扩大的。(C)2016年6月，作者。爱思唯尔有限公司出版
The aim of this work is to measure the development of the concentration of quota holdings by harvesting companies and harbours in Iceland. For the period 1990-2014, the analysis traces the development of relative quota holdings of the biggest actors operating large vessels as well as firms that employ smaller boats that are only allowed to use hook-and-line. A more detailed data set is used for the period 20012014 which allows for a more thorough investigation of consolidation in both fleet segments using Herfindahl-Hirchman Indexes, Gini coefficients and Lorenz-curves. The biggest firms in the two fleet segments increased their share of quotas throughout the period but the quota market is though still quite competitive. The distribution of quotas between firms has become more unequal, and there is also clear evidence of increasing transfers between harbours, especially in the case of the quota shares of hook and -line boats. However, the results also indicate that spatial concentration has been much less than consolidation at firm level during the period under consideration. This would indicate that firms have mostly grown in size by merging with local firms or buying out smaller local operators. (C) 2016 The Authors. Published by Elsevier Ltd.
