Protected agriculture producers in Zacatecas are facing the challenge of participating in the global markets with sustainable income. A viable way would be to increase their upgrading capability. This work determines the relationship between upgrading and collective efficiency of the tomato cluster under protected agriculture in Zacatecas. Information was obtained through a survey among technicians, complemented with interviews |with owners of the production units, researchers and government authorities. Applying cluster analysis technique, a classification of production units by technological level was made. By these means we obtained the collective efficiency index, the value chain pattern of governance of the value chain in which enterprises participate and the upgrading pattern. External economies were more dominant than joint actions. Collective efficiency and upgrading were positively correlated. A high technological level is a necessary but insufficient condition for enterprises competitiveness in the global market, so that an increase in upgrading capability is required.

Palavras-chave : external economies; joint action; greenhouses.
