Quelle intelligence peut-on trouver dans les données massives ? La cas des marchés publics français

Mis en avant

L’objet de cet article est d’expliquer comment les données des marchés publics peuvent être considérées comme des « big data », dans lesquelles il est possible de trouver de « l’intelligence ». Pour cela, nous faisons une analyse longitudinale des avis d’attribution issus du Bulletin Officiel des Annonces de Marchés Publics (BOAMP) sur la période 2006-2010. Les résultats montrent que les données massives permettent d’extraire des indicateurs structurels qui facilitent la prise de décision stratégique de l’acheteur public pour structurer ses appels d’offres et renforcer son pouvoir de décision dans la sélection des fournisseurs. Cela pose, ainsi, les fondements de futures applications d’intelligence économique dédiées aux achats publics.

How does performance history impact supplier selection in the public sector?

Mis en avant

The paper studies if the performance history impacts supplier selection in the French public sector context. While French public procurement legislation forbids consideration of the past contract wins in supplier selection, public contractors may still rely on contract win history for highly complex transactions.  Using French Official Journals (BOAMP), we collected all public procurement transactions of 976 suppliers that had at least one transaction per year, over a period of six years (between 2006 and 2011). We conducted a two-level hierarchical linear auto-regression analysis and a feature evaluation analysis for all transactions.  The paper finds significant variation between the transactions of different markets, as well as in the overall positive impact of past wins and in the detailed impact patterns and thresholds of each market. The findings may allow refinement of existing contract awarding strategies and of current legislation.  The paper aims at empirically testing whether a supplier’s degree of success in any given year, measured by the number of public contracts won, may have an impact on the likelihood that the same supplier is awarded a public contract the following year. We conclude that suppliers retained for public contracts could benefit from building public buyers’ loyalty using a key account selling approach rather than systematically seeking to acquire new contracts.

Out of sight, out of mind? Supplier spatial proximity in French public procurement

Mis en avant

The paper studies the impact of spatial proximity on supplier selection in the French public sector. While French public procurement legislation forbids consideration of supplier location in the procurement process, public contractors may still rely on spatial proximity for complex transactions necessitating mutual adjustments with suppliers.
Using French Official Journals (BOAMP), we compiled 565,557 transactions completed on three public procurement markets between 6,182 contractors and 26,570 suppliers, over a period of six years (between 2006 and 2011). We conducted a two-level hierarchical linear auto-regression analysis and a feature evaluation analysis for all transactions.
The paper finds significant variation between the transactions on different markets: a negative effect of spatial proximity on the number of contract notices in the public market and a positive effect of spatial proximity on the number of notices in the services and supplies markets. The difference lies in the levels of mutual adjustment required to optimally manage the relationship between public contractor and supplier.
The research is based on an econometric analysis conducted uniquely in the French context, which calls into question the external validity of the results obtained. The study also rests on segmentation into three aggregate markets, which might be considered too general.
Rather than analyze public contractors’ perceptions of the importance of the criterion of spatial proximity, the paper examines 565,557 actual transactions. The results point to the emergence of a new type of relationship with certain suppliers, which should lead public contractors to integrate relationship management competencies, in addition to legal and economic competencies, in the organization of calls for tenders.
