Abstract
In recent decades economic theory has highlighted the benefits produced by networks of organizations in fostering innovation. A number of public policies were put in place to favor these innovation networks throughout Europe. The top-down institution of a number of specialized technological districts in Italy has been one of the main outcomes of this new wave of policies, in mid-2000. The aim of this paper is to explore what impact the institution of technological districts had on collaborative patterns over time. Using a pre-specified blockmodeling, observed network configurations obtained by the co-participation to R&D projects undertaken by organizations involved in a technological district are compared with a theoretical core-periphery structure in a 8-years time interval. The analyses of networks over time show that collaborative patterns have evolved from a core-periphery structure towards a complete network in which each research group is connected with the others.

Notes
- 1.
In this study we use a direct approach consisting of analyzing the original data without transforming them into dissimilarities/similarities measures.
- 2.
We thank the IMAST’s administrative staff who helped us updating the data to July 2012. The network at time 1 (2005) has not been included in the further analysis, given that only one project has been started.
- 3.
In our case it is possible to know the exact year when a link is created/terminated and when a member is entered or withdrawn from the network according to the time duration of each research project.
- 4.
A penalty of 100 was imposed on this block to force the model to be as consistent as possible with a theoretically defined core-periphery configuration. Results both with and without this penalty are not too different.
