GOMEZ-CARRETO, Tlillalcapatl et al. Critical mass and innovation environment in the tomato production system, Chiapas. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.spe15, pp.2949-2964. ISSN 2007-0934.

The social network analysis applied to the study of local productive systems (innovation networks) contributes to glimpse the complexity of the processes of technological innovation and transfer in the rural sector, by characterizing the links established the various participating stakeholders and that eventually they could be regional innovation environments. This study analyzed in an exploratory manner the innovation network of tomato production system in the Plateau Comiteca, Chiapas, Mexico, using the census triads, in order to glimpse the potential of an analysis algorithm with methodological rigor that contributes to support decisions public policy around improving the process of diffusion of agricultural innovations into local production systems. From 2012 to 2013 the collection of field data was performed, the characterization of the actors of the network and the census UCINET v triads using the program. 6 509. To 52 interviewed snow ball technique was possible to map nodes 218 and 245 promoters evidence it found of triads that are establishing ties of cooperation within the framework of technological innovation process of a total of 1 703 016. This disproportion could explain the incipient consolidation of the productive system.
