This paper examines the relationship between the structure of corporate governance and performance in the banking sector. A sample has been selected using the generalized method of moment (GMM) approach. The sample consists of data from a total of 33 Turkish, Tunisia, Morocco and Lebanon banks which are listed in stock during the period between 2012 and 2017. Since this paper emphasizes corporate governance, a “Board Characteristics Index” was developed based upon four different aspects of the board composition—board leadership structure, board member characteristics and board committee structure. It also demonstrates how the overall index relates to banking performance. The results show that the governance index, which aggregates with the four sets of board attributes relate significantly and positively with return on assets.

本文研究了银行业公司治理结构与绩效之间的关系。已使用广义矩量法（GMM）方法选择了一个样本。该样本包含来自2012年至2017年期间上市的总共33家土耳其，突尼斯，摩洛哥和黎巴嫩银行的数据。由于本文着重于公司治理，因此根据四种不同的情况制定了“董事会特征指数”董事会组成方面-董事会领导结构，董事会成员特征和董事会委员会结构。它还说明了整体指数与银行绩效之间的关系。结果表明，与四组董事会属性聚合的治理指数与资产收益率显着正相关。
