Strategic Network

To analyze strategic networks, we have chosen to study the responses, through co-transacting, to invitation to tender in French public markets. Our study is based on the analysis of coalition relationships within company groups.

Data used for this study issues from the attribution notices from of the French Official Journals (BOAMP). From transactions made in 2008, we have selected, with key words, the transactions held only by groups of companies.

Table 1 details the census of the observed businesses. It shows the number of parties that we identified within the groups. Obtaining this data goes through a multi-stage process: extraction, cleaning, filtering, formatting, dedoubling and indexing. The nature of the data used to analyze the groups of companies is held by three variables. The first is allotted to the identification of the parties (business reasons). The second is ascribed to the type of beneficiaries of the transactions (company groups). The third variable concerns the cooperative relation which links the parties within a group. We have considered that there is a cooperative relationship with two companies when they obtain a market within the bounds of co-transaction (a belonging to a group of companies).

French contract award records

The data were taken from the contract award records of the Bulletin Officiel des Annonces des Marchés Publics (BOAMP). From 2006 to 2011, 565,557 transactions completed between 6,182 contractors (procurers) and 26,570 suppliers were analyzed.

The BOAMP compiles calls for tenders and contract award results at the state, local community and public establishment levels. The contract award notice states the public procurer’s decision, along with the following information: identification of the principal and the tenderers, the type of market, type of procedure, awarding criteria, and publication date. The distribution of transactions by sector is based on the CPV (for Common Procurement Vocabulary) classification.

The CPV is the reference nomenclature for public markets adopted by the European Parliament. The CPV assigns a nine-digit code to about 6,000 terms generally used in awarding contracts on public markets. To simplify the analysis, we have retained three main sectors.

  • The works market, which covers building construction or civil engineering projects (e.g. construction of a hospital or road repairs).
  • The service market, which covers building cleaning and maintenance, and household waste collection services.
  • The goods market, which covers provision of capital equipment and consumer goods (e.g. furniture or office supplies). provides free access to its datasets.To download datasets click here: french prublic procurement in 2008
