In this study we explore market power in 13 euro area banking sectors for the years 2007 to 2019 by means of a structural model framework with demand and supply equations, where the mark-up of price over marginal cost is parameterized as a measure of banks’ conduct that depends on selected factors. Our evidence indicates that EU banks enjoy a significant degree of market power, which shows a decreasing trend over time and some difference across countries. More competition is associated with higher bank density, lower bank capitalization, more efficient and stable banking systems, better macroeconomic conditions, and the establishment of the SSM. Finally, a clear convergence pattern emerges in the behaviour of EU banks.

在这项研究中，我们通过具有需求和供应方程的结构模型框架探索了 2007 年至 2019 年欧元区 13 个银行业的市场支配力，其中价格相对于边际成本的加价被参数化为衡量银行取决于选定因素的行为。我们的证据表明，欧盟银行享有很大程度的市场支配力，随着时间的推移呈下降趋势，各国之间存在一些差异。更多的竞争与更高的银行密度、更低的银行资本、更高效和稳定的银行系统、更好的宏观经济条件以及 SSM 的建立有关。最后，欧盟银行的行为出现了明显的趋同模式。
