This study aims at identifying the indicators in the fields of science and technology, which factors determine the sustainability of investment policies on science, research and innovation, among Iberoamerican countries. For this, Ricyt indicators have been adopted (Iberoamerican Network of Science, Technology and Innovation), and based on results, two sustainability models are designed focused on two parallel equations. The first model supports sustainability and appropriateness of scientific and technological activities. The second model, however, describes the dependence on sustainability based on social responsibility and structure initiative. It is really expected that the results shown by these two models be more robust than those resulting from each of these models in isolation.
