Purpose

The study aims to extend the conventional triple bottom line (TBL) framework (prosperity, people and planet) to the quadruple bottom line (QBL) by newly adding a “prophet” dimension for Islamic banks seeking compliance with Islamic law in their pursuit of sustainability.

Design/methodology/approach

Employ Chapra's corollaries of maqasid al-shari'ah (the goals of Islamic law) to develop constructs for a survey of 504 Islamic bank stakeholders from five Indonesian provinces to gather primary data to quantitatively verify the dimensions and items in the proposed QBL framework. Categorical principal component analysis (CATPCA) then identifies the sustainability of ten Islamic banks from ten countries as a trial application of the resulting QBL index.

Findings

Using the dimensions and items identified using CATPCA, the authors develop a QBL index to assess the sustainability of the ten Islamic banks. The findings suggest that half of the banks are sufficiently sustainable, with three being proactive (doing more than is required) and two being accommodative (doing all that is required). The remaining five banks are unsustainable, with two banks being defensive (doing the least that is required) and three being reactive (doing less than is required). Most of the banks perform relatively poorly according to the “planet” (38%) and “people” (41%) dimensions and perform better on the “prosperity” (53%) and “prophet” (63%) dimensions. Nonetheless, there is ample room for improvement across all dimensions of sustainability.

Research limitations/implications

The generalizability of the findings is limited by the small-scale single-country survey used in the CATPCA part of the analysis. Only ten Islamic banks were included in the QBL scoring and ranking exercises

Practical implications

Islamic banks can improve their sustainability by increasing green financing and reaching out to rural areas and disadvantaged populations. In countries with Islamic banking systems, regulators can support this through training, guidance and incentives.

Originality/value

Pioneering exploration of TBL from maqasid al-shari'ah perspective. First, we develop a QBL index to assess the sustainability of Islamic banks in line with actual stakeholder expectations.

伊斯兰银行业的可持续性：使用新型四重底线框架的理论和证据

目的

该研究旨在通过为寻求遵守伊斯兰法律以追求可持续性的伊斯兰银行新增一个“先知”维度，将传统的三重底线 (TBL) 框架（繁荣、人类和地球）扩展到四重底线 (QBL)。 .

设计/方法/方法

利用 Chapra 的maqasid al-shari ' ah（伊斯兰法的目标）的推论，为来自印度尼西亚五个省的 504 名伊斯兰银行利益相关者的调查开发结构，以收集原始数据，以量化验证提议的 QBL 框架中的维度和项目。然后，分类主成分分析 (CATPCA) 将来自 10 个国家的 10 家伊斯兰银行的可持续性确定为由此产生的 QBL 指数的试验应用。

发现

使用 CATPCA 确定的维度和项目，作者开发了一个 QBL 指数来评估十家伊斯兰银行的可持续性。调查结果表明，一半的银行具有足够的可持续性，其中三个是主动的（做的比要求的多），两个是宽松的（做所有要求的）。其余五家银行是不可持续的，其中两家银行是防御性的（做最少的要求），而三家是被动的（做不到要求的）。大多数银行在“行星”（38%）和“人”（41%）维度表现相对较差，在“繁荣”（53%）和“先知”（63%）维度表现较好。尽管如此，在可持续性的各个方面仍有很大的改进空间。

研究限制/影响

调查结果的普遍性受到 CATPCA 部分分析中使用的小规模单一国家调查的限制。仅 10 家伊斯兰银行被纳入 QBL 评分和排名练习

实际影响

伊斯兰银行可以通过增加绿色融资和接触农村地区和弱势群体来提高其可持续性。在拥有伊斯兰银行系统的国家，监管机构可以通过培训、指导和激励措施来支持这一点。

原创性/价值

从maqasid al-shari ' ah 的角度对 TBL 的开拓性探索。首先，我们开发了一个 QBL 指数，以根据实际利益相关者的期望来评估伊斯兰银行的可持续性。
