Medium risk #10 Concentration

Supplier concentration (HHI)

Markets where an authority's money went to a few suppliers, although the country had hundreds.

The Herfindahl-Hirschman index (HHI) shows how concentrated a market is: 10,000 means a single supplier; the lower it is, the more suppliers share the money. Here a market is one authority, one CPV group and one year. The CPV group matters: over all of an authority's suppliers the index would measure what it bought, not who it bought from. The same authority can have competition for fuel and a single supplier for IT services.

Concentrated money, by CPV group

The 12 largest CPV groups by value; the other 101 are added into a single tile.

National concentration index by year

The index, like the rate in the year chart, is computed on every market checked, not only the flagged ones.

How it is computed

The index is computed per market, not per authority, and only on money spent.

  1. Every award in the three streams (tenders, direct purchases and offline purchases) since 2018 is taken.
  2. Each award gets its CPV group (three digits), supplier and year: the contract date for tenders, the finalisation date for the others. A contract over several lots is split by estimated value; an association's contract is split among its members.
  3. Money is added up by authority, CPV group, year and supplier. Each market is also tested once over the whole period, on the money of every year together, where a supplier present in three years holds one share.
  4. The index is the sum of the squared supplier shares, times 10,000. The lowest possible value is 10,000 divided by the number of awards.
  5. Only markets large enough are included: above the money and award thresholds. A market with three awards cannot go below 3,333, however fairly it was shared.
  6. Markets with an index above the threshold are flagged, if the country had enough suppliers in the CPV group for a choice to exist.

Thresholds

  • Flagging threshold: an HHI of at least 7,000
  • At least 10 awards in a year, 30 over the whole period
  • At least 500,000 RON in a year, 3,000,000 RON over the whole period
  • At least 20 suppliers active in the CPV group nationally

The index says nothing about lawfulness: a concentrated market can come from fair tenders won by the same bidder every time. Markets below the thresholds above are left out, and framework agreements are excluded.

The CPV group approximates the market. Some groups are local monopolies (waste, water, district heating), where the national supplier count overstates the buyer's real choice, and the indicator will flag them. The Suppliers in the market column helps recognise them.

The full explanation, on the methodology page

The markets flagged in 2024, with shares and floors (10 awards, 500,000 RON) taken on that year's money alone. The whole period is a separate test, not the sum of the years.

Rows per page: 25 50 100
Contracting authority
The authority that spent. The name leads to its profile.
CPV group
The three-digit CPV group: the market the index is computed on.
Year
The year the market was tested in. Whole period is a separate test on the money of every year together, with higher floors; it is not the sum of the years, and a market flagged in a year can be missing from it.
Spent
The money spent in this market. Underneath, by stream (tenders, direct, offline), each linked to the listing it was computed from.
Awards
How many awards the market holds. The lowest possible index depends on it: 10,000 divided by this number.
Suppliers used
How many suppliers were paid. Click the figure to list them under the row, with each one's share.
Suppliers in market
How many suppliers sold in this CPV group across the country that year. A high index with five suppliers nationally is the market; with nine hundred, it is a choice.
HHI
The sum of the squared shares, times 10,000: 10,000 means a single supplier. The hint beside the figure shows the lowest possible value for the number of awards.
Leading supplier
The supplier with the largest share, and its share. The supplier filter searches every supplier in the market.
