This paper seeks to contribute to the analysis of the bank efficiency in the European Union in the aftermath of the recent crisis, using Data Envelopment Analysis (DEA) and considering a sample of 485 banks from all current EU member-states between 2011 and 2017. The results obtained confirm the existence of bank inefficiency,and that this inefficiency is mostly due to inefficient managerial performance and bad combinations of the considered bank inputs and outputs. The results also provide enough evidence of appropriate scale production and dynamic technological changes during the considered interval. Moreover, the results obtained using panel estimates to explain the bank total factor productivity changes allow us to conclude that the choices of the banks in terms of the fixed assets,the profit before tax to the average assets, as well as the ratio of the off-balance sheet items to total assets contribute positively to the productivity changes. On the other side, the ratio of the impaired loans to equity, and the bank interest margins are not in line with the total factor productivity changes of the EU banking sector.

使用数据包络分析评估欧洲银行效率：近期金融危机后的证据

本文旨在通过使用数据包络分析 (DEA) 并考虑 2011 年至 2017 年间来自所有当前欧盟成员国的 485 家银行的样本，为最近危机后欧盟银行效率的分析做出贡献。获得的结果证实了银行效率低下的存在，这种低效率主要是由于管理效率低下和考虑的银行输入和输出的不良组合。结果还提供了足够的证据，证明在所考虑的时间间隔内适当的规模生产和动态技术变化。此外，使用面板估计来解释银行全要素生产率变化的结果使我们能够得出结论，银行在固定资产、税前利润与平均资产方面的选择，以及资产负债表外项目与总资产的比率对生产率变化有积极贡献。另一方面，减值贷款与权益比率、银行息差与欧盟银行业全要素生产率变化不符。
