The Statistic on scientific research and technological development (R&D) activities has the main objective of measuring economic and human resources for research by all the economic sectors of the country (companies, public institutions, higher education institutions and private non-profit institutions) with the aim to:

  • To provide an instrument for management, planning, decision-making and control in terms of national scientific policy.
  • To provide statistical bodies with the information that they request, obtained in accordance with the international regulations that allow for comparability between the different countries.
