Purpose

This study aims to investigate the effects of board cultural diversity (BCD) and board gender diversity (BGD) of the board of directors on environmental, social and governance (ESG) performance in the European banking sector using resource-based view (RBV) theory. In addition, this study analyses the linkages between BCD and BGD and knowledge sharing on the board of directors to improve ESG performance.

Design/methodology/approach

This study selected a sample of European-listed banks covering the period 2021. ESG and diversity variables were collected from Refinitiv Eikon and analysed using the ordinary least squares model. This study was conducted in the European context regulated by Directive 95/2014/EU, which requires sustainability disclosure. The original population was represented by 250 banks; after missing data were excluded, the final sample comprised 96 European-listed banks.

Findings

The findings highlight the positive linkages between BGD, BCD and ESG scores in the European banking sector. In addition, the findings highlight that diversity contributes to knowledge sharing by improving ESG performance in a regulated sector. Nonetheless, the combined effect of BGD and BCD negatively impacts ESG performance.

Originality/value

To the best of the authors’ knowledge, this is the first study to measure and analyse a regulated sector, such as banking, and the relationship between cultural and gender diversity for sharing knowledge under the RBV theory lens in the ESG framework.

文化和性别多样性对知识共享 ESG 绩效的影响：来自欧洲银行的经验证据

目的

本研究旨在利用资源基础观（RBV）理论探讨欧洲银行业董事会文化多样性（BCD）和董事会性别多样性（BGD）对环境、社会和治理（ESG）绩效的影响。此外，本研究还分析了 BCD 和 BGD 之间的联系以及董事会知识共享以提高 ESG 绩效。

设计/方法论/途径

本研究选取了 2021 年欧洲上市银行的样本。ESG 和多样性变量从 Refinitiv Eikon 收集，并使用普通最小二乘模型进行分析。这项研究是在受 95/2014/EU 指令监管的欧洲背景下进行的，该指令要求披露可持续性。最初的人口由 250 家银行代表；排除缺失数据后，最终样本包括 96 家欧洲上市银行。

发现

调查结果强调了欧洲银行业 BGD、BCD 和 ESG 评分之间的正相关关系。此外，研究结果强调，多样性有助于提高受监管行业的 ESG 绩效，从而促进知识共享。尽管如此，BGD 和 BCD 的综合效应会对 ESG 绩效产生负面影响。

原创性/价值

据作者所知，这是第一项衡量和分析银行业等受监管部门以及文化和性别多样性之间关系的研究，以在 ESG 框架的 RBV 理论视角下共享知识。
