Methodological note. EIS: Public-private co-publications per million population

Data are two-year averages. The quantity of public-private co-publications is highly skewed across countries and this indicator has no pre-determined maximum value: a square root transformation will therefore be used to reduce the volatility and skewed distribution of scores in this indicators.

The indicator is obtained as a quotient.

Numerator:

Number of public-private coauthored publications. The “public-private co-publications” are defined as all research-related papers (document types: `research articles´, `research reviews´, `notes´and `letters´) published in the Web of Science database. These co-publications have been allocated to one or more countries according to the geographical location of the business enterprise (or enterprises) that are listed in the authors affiliate address(es); as a result the geographical location of the public sector research partener(s) in those addresses is not relevant. Each co-publication is counted as one publication for each country, irrespective of the number of co-authors and (parent) organisations listed in the author affiliate address(es).

Denominator:

Total population as defined in the European System of Accounts (ESA 1995).

Data are two-year averages.
