Sustainable Procurement Practices and Household Purchase Decisions in Oyo State

Abstract

This study explored the influence of two sustainable procurement strategies, Strategic Sourcing
and Green Procurement on household purchasing behaviour in Oyo State, Nigeria. Responding to
a gap in existing literature that predominantly focuses on corporate procurement contexts, the study
adapted procurement constructs to the domestic domain, anchored on social cognitive theory. A
descriptive survey design was employed, with a sample size of 399, data was gathered using a
structured questionnaire and analysed. Findings revealed that strategic sourcing with regression
coefficient of 0.1346 and a t-statistic of 8.2048 (p < 0.001) and green procurement with regression
coefficient of 0.1124, a t-statistic of 6.9069 (p < 0.001) is statistically significant and has a positive
influence on household purchasing decisions. The study concludes that sustainable procurement
philosophies are increasingly reflected in household consumption patterns. It recommends that
stakeholders promote procurement literacy and sustainability values through community
programmes, vendor partnerships and locally grounded environmental initiatives. The research
contributes to existing procurement theory by demonstrating that strategic sourcing & green
procurement which was traditionally associated with corporate and institutional settings are also
relevant and impactful in household-level decision-making. The study broadens the conceptual
boundaries of sustainable procurement and validates its applicability beyond organizational
contexts.
