Resumen
This paper highlights the importance of scientific publications produced by Mexican researchers in journals that are listed in Scopus and Web of Sciences (WoS). This research found that 98% of these publications were written by members of the National System of Researchers (SNI, by its acronym in Spanish), hence the importance of strengthening this organization. The paper also analyses the evolution of the funds that have been invested in science and technology; financing represented only 0.40% of the GDP (Gross Domestic Product) from 2000 to 2017. Therefore, it is concluded that such a variable is not determining enhancing scientific production among Mexican researchers. It is stated that per capita income growth within a country could improve the conditions for scientific production; however, in Mexico, this indicator was barely 0.8% annually; therefore, it is not a significant variable regarding the growth of Mexican publications. Mexico has gained importance in world science explained by a growth in the number of researchers and their willingness to participate in the production of knowledge.
