本文研究了自单一内部市场创建以来欧洲银行市场的生产效率是否有所改善和趋同。使用源自 DEA 估计的效率指标，使用 Tobit 回归模型方法评估欧洲银行效率的决定因素。然后，通过认识到 DEA 效率得分在回归分析中使用时的固有依赖性问题，对银行效率决定因素建模的现有文献进行了扩展。为了克服依赖性问题，应用了引导技术。总体而言，结果表明，自欧盟单一市场计划以来，银行效率水平略有提高，尽管没有证据表明这些水平已经趋同。结果还表明，从非自举回归分析中得出的对银行效率决定因素的推论可能存在偏见和误导。
This paper investigates whether there has been an improvement in and convergence of productive efficiency across European banking markets since the creation of the Single Internal Market. Using efficiency measures derived from DEA estimation, the determinants of European bank efficiency are evaluated using the Tobit regression model approach. The established literature on modelling the determinants of bank efficiency is then extended by recognizing the problem of the inherent dependency of DEA efficiency scores when used in regression analysis. To overcome the dependency problem, a bootstrapping technique is applied. Overall, the results suggest that since the EU's Single Market Programme there has been a small improvement in bank efficiency levels, although there is little evidence to suggest that these have converged. The results also suggest that inference on the determinants of bank efficiency drawn from non-bootstrapped regression analysis may be biased and misleading.
