This study conducts an across-the-board comparative analysis of the impact of the main measures used by the 10 leading maritime nations of the EU on the relative competitiveness of the fleets that they control, covering the period from 1996 to 2011. We propose two models to compare the relative effectiveness of the maritime policy measures implemented: one for the full set of countries and measures and the other specifically for each maritime nation. The estimation results make us conclude that generally the measures adopted in national-level maritime policies (tonnage tax, second register and other measures) seem to have been effective in that they have had a positive effect on the competitiveness of controlled fleets, but with uneven impact on the fleets of each country.

国家援助，欧盟海上运输政策以及欧盟国家船队的竞争力

这项研究对1996年至2011年期间欧盟的10个主要海事国家所采用的主要措施对其所控制船队的相对竞争力的影响进行了全面的比较分析。我们建议采用两种措施比较执行的海事政策措施的相对有效性的模型：一种适用于整套国家和措施，另一种专门针对每个海事国家。估算结果使我们得出结论，总体而言，国家级海事政策中采取的措施（吨位税，二次登记和其他措施）似乎是有效的，因为它们对受控船队的竞争力产生了积极影响，但效果不均对每个国家机队的影响。
