The apparel and textile industry is the backbone of the Sri Lankan economy,
contributing significantly to the country’s gross domestic product (GDP). The
coronavirus (COVID-19) pandemic, which also triggered the ongoing economic
crisis in Sri Lanka, has a profound effect on the organizational performance of
apparel sector firms in Sri Lanka. In this context, the study examines the
impact of multi-dimensional corporate sustainability practices on organizational
performance in the said sector. The study employed the partial least squares
structural equation modelling (PLS-SEM) technique for analysing and testing the
hypothesis of the study while using Smart PLS 4.0 software as the analysis tool.
Relevant data were collected through a questionnaire from 300 apparel firms
registered with the Board of Investment of Sri Lanka (BOI). The study results
indicated that "economic vigour,” “ethical practices," and "social equity" have
a significant impact on organizational performance, while "corporate governance"
and "environmental performance" have an insignificant impact. Unique discoveries
from this study would be useful to prosper organizational performance and
formulate novel sustainable future strategies not limited to the garment
industry even during harsh economic conditions.
