This presentation analyzes the evolution of transdisciplinarity within the community of ecological economics. Using underexploited data until now, we used the methodology of the social network analysis to study the evolution of the network of co-publications in the journal «Ecological Economics». After having describing the global characterization of the networks during 4 periods, the role of authors that have key positions (central or intermediate) in the co-publications' network of each periodis assessed regarding their background and career-path. Results suggest that the ecological economics community is more scattered and that actors having key position do not centralize or intermediate for transdisciplinarity. Reasons may be that the editorial choices prioritize other criteria over transdisciplinarity, or that more and more authors define themselves as «ecological economists».
