Este análisis emplea una base de datos con información de 27,667 investigadores mexicanos que han formado parte del Sistema Nacional de Investigadores (SNI), al menos por un año, en el periodo 1991-2011, e integra 122,406 artículos publicados por dichos científicos en revistas ISI. A fin de determinar la cantidad y calidad de la productividad de las IES, se consideraron como unidades de medida los artículos de publicaciones científicas y las citas bibliográficas. Los resultados indican que únicamente el 28% de las IES analizadas emitieron uno o más artículos en el periodo de estudio. Adicionalmente, nuestros resultados muestran que en diez universidades se agrupa tanto la mayor cantidad de artículos publicados, como la mayor cantidad de citas bibliográficas. Por otra parte, se muestra que la edad máxima de productividad es a los 58 años para el caso de las investigadoras y 57 años para los investigadores. Finalmente, una de las contribuciones de este trabajo es que muestra que las actividades de colaboración están en continuo crecimiento entre los investigadores.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The aim of this paper is to analyze how a system of economic stimulus and recognition to the research activities in Mexico has impacted the scientific productivity of Higher Education Institutions (HEI). This analysis uses a database with information of 27,667 Mexican researchers who have been benefited from the Sistema Nacional de Investigadores (SNI) at least for one year among the period 1991-2011 and includes 122,406 articles published by these researchers in ISI journals. In order to determine the quantity and quality of the productivity of HEI we considered as units of measurement the publications and citations. The results indicate that only 28% of the HEI analyzed issued one or more publications in the study period. Additionally, our results show that in 10 universities are grouped both the higher quantity of publications and the higher quantity of quotes. Moreover, it is shown that the maximum age of productivity is at 58 years in the case of the female researchers and 57 years for male re searchers. Finally, one of the main contributions of this work is that it show that collaboration activities are continuously growing among researchers.]]></p></abstract>
