SANCHEZ GOMEZ, Julia; RENDON MEDEL, Roberto  e  CERVANTES ESCOTO, Fernando. Effect of the intervention of an agent of change in local innovation networks. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.spe15, pp.3023-3037. ISSN 2007-0934.

The aim of this research was to analyze over time the impact of the intervention agency innovation management (AGI) in small sheep farms in the State of Mexico. The network of 78 sheep producers in Atlacomulco and Jilotepec Mexico State delegations were mapped for three time points: moment I, before surgery (2007); moment II, with the intervention (2009) and moment III, after the intervention (2011). The unequal attention (direct and indirect) provided by the agent of change to sheep farms caused significant differences between groups. During the intervention of the AGI, producers with direct care improved their position in the network, the value of social indicators (grade and input coverage) and their level of adoption of innovations was higher (p< 0.01) than indirect attention. The impact of the intervention of the change agent in sheep farms with indirect attention was reflected in the association of social indicators (output level, nodal density and power bonacih) and adoption of innovations (p< 0.1). It is concluded that the change agent to intervene by selecting a population with direct care in network innovation, favors the number of connections between producers, facilitates access, exchange and scope of information between producers.
