The aim of this paper is to provide empirical analysis of the geographical mobility of PhDs during the beginning of their career, by using long term data (1970-2000) about France. First of all, we highlight the low mobility of PhDs: more than 60% of them supervise their first PhD in the region...

The purpose of this article is to provide possible answers, at an empirical level, to the question "Does geographical proximity still matter in collaborations for innovation?", since the lack of available data has made it impossible to provide real answers up to now. Relying on two real...

The aim of this paper is to provide explanatory elements of the geography of collaboration by testing various potential factors related to the partners' features (sector of activity, location, affiliation to a parent firm, ...) and to the pair of regions involved in the partnership (economic and...

The aim of this paper is to provide new insights about the dynamic of the geography of knowledge collaborations and structural effects, such as size effects. We propose, in a first part of the paper, a theoretical model of partners adoption that highlights the potential roles in the geography of...

La littérature économique qui traite de la géographie de l'innovation se focalise généralement sur les contraintes qui pèsent sur les acteurs au moment du processus de collaboration, en insistant notamment sur la dimension tacite des connaissances, qui imposerait des rapports de face à...

L'objectif de cet article est de se prononcer sur l'évolution de la dimension spatiale des collaborations pour l'innovation et sur l'existence d'éventuels effets de structure et notamment d'effets-taille. Nous développons dans un premier temps un modèle d'adoption des collaborateurs, qui met...

Social embeddedness appears to be a promising way to analyze knowledge collaborations, notably to better understand their build up and their spatial patterns. Nevertheless, measurement problems and an over-territorialized conception of the notion exist. When studying the formation of these...

This paper attempts to give explanations of environmental collaborations, as few works have focused empirically on this topic, given the lack of precise data. We aim to explain what, why, where, and with whom firms collaborate (or not)? We used more than 300 data on environmental innovations...

Based on a Marshallian perspective, most of the spatial analysis underlines the importance of two elements for innovation: the sectoral specialization, on the one hand, and the spatial agglomeration, on the other. Technological clusters are thus highly recommended by several developed countries...
