English

This study evaluates Nigeria's digital procurement reforms and proposes a Policy-Driven Digital Governance Framework (PDGF) integrating AI anomaly detection, OCDS, and gender-responsive green procurement. Simulation suggests potential savings of NGN 1.8 trillion annually and 330,000 green jobs by 2030.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では公共調達のグリーン化が進むが、本論文のAI活用やOCDS導入は日本の調達DXに示唆を与える。特にSSBJ開示やサプライチェーン排出量算定に繋がるグリーン調達指標の設計は参考になる。

In the global GX context

This paper contributes to global discourse on sustainable public procurement, offering a framework that integrates AI and open data standards. It provides empirical evidence from Nigeria on the impact of digital reforms, relevant for countries implementing green procurement policies under ISSB or CSRD.

👥 読者別の含意

🔬研究者:Provides a mixed-methods framework for evaluating digital procurement reforms and a simulation model for green procurement impacts.

🏢実務担当者:Offers a blueprint for integrating sustainability criteria into procurement systems, including AI-based monitoring and gender-responsive clauses.

🏛政策担当者:Highlights the need for legislative changes to mandate ESG indicators in procurement and proposes a Sovereign Green Procurement Index.

📄 Abstract（原文）

Although 15–20% of Nigeria's GDP comes from public procurement (World Bank, 2022; OECD, 2021), systemic leakages, elite capture, and gender exclusion still exist 17 years after the Public Procurement Act of 2007 (The A & E Law Partnership, 2024; Oyewobi et al., 2017). Using a sequential-explanatory mixed-methods design, this study evaluates the causal effects of BPP's digital reforms (2012–2023) on procurement efficiency (Creswell, 2014; Tashakkori & Teddlie, 2010). Additionally, it suggests a Policy-Driven Digital Governance Framework (PDGF) that incorporates AI-enabled anomaly detection, a sovereign Open Contracting Data Standard (OCDS) cloud hosted by the National Data Exchange (NDX), and gender-responsive green procurement (GRGP) regulations (Lawal Rasheed Ajibola et al., 2025; OBAZELE & OSUJI, 2025). Only after the 2021 Executive Order on OCDS required granular transparency did e-bidding implementation reduce average cycle time by 22% (p<0.01) and bid-rigging red flags by 18% (p<0.05), according to difference-in-differences estimates on 4,000 federal contracts (OBAZELE & OSUJI, 2025; Krasnolutska, 2020). Qualitative elite interviews (n=37) show that sustainability clauses are still optional rather than required because the PPA 2007 does not include provisions for environmental, social, and governance (ESG) indicators (The A & E Law Partnership, 2024; Federal Ministry of Environment, 2023) (Onyango, 2019; Feiock, 2013). In order to close this gap, the paper drafts a Procurement Sustainability Bill 2025 that modifies Sections 16, 30, and 58 of the PPA to include requirements for the circular economy, a 30% set-aside for women-owned SMEs, mandatory life-cycle costing, and a Sovereign Green Procurement Index (SGPI) (Bolton, 2021; UN Women, 2023). According to simulation modeling, SGPI could save NGN 1.8 trillion (€USD 2.4 billion) a year by 2030 and create 330,000 green jobs (Oyewobi et al., 2017; Geels, 2020). According to the report (Lawal Rasheed Ajibola et al., 2025; The A & E Law Partnership, 2024), BPP has the potential to lead the continent in inclusive, sustainable, and sovereign procurement governance.
