Abstract
This chapter presents an empirical study on formation of multilateral R&D collaboration networks among organizations. The objective of the study is to investigate how geography and heterogeneity in institutional types affect the way organizations come together around consortiums to perform R&D. It makes use of data on project proposals submitted to the 7th Framework Program (FP) in the field of biotechnology to construct a two-mode network. It employs extensions of exponential random graph models (ERGM) (Frank and Strauss, J Am Stat Assoc 81(395):832–842, 1986; Wasserman and Pattison, Psychometrika 61(3):401–425, 1996, for affiliation networks (Wang et al., Soc Netw 31:12–25, 2009). The results show that higher education institutions and research institutions tend to show higher connectivity and hence bridge learning across consortiums. Furthermore, organizations located in the core European countries tend to participate in the same consortium and these consortiums tend to be small in size. Finally, homophily in institutional types and network effects do not affect the formation process.

Notes
- 1.
For statistical and mathematical foundations of ERGM, readers are referred to the joint probability of a Markov field or the extensions of statistical mechanics of Gibbs to the study of networks by Park and Newman (2004), and to the Hammersely Clifford Theorem (Besag 1974) proving the Gibbs-Markov equivalence.
- 2.
Regulation (EC) No 1906/2006; Article 5/(1) states that “at least three legal entities must participate, each of which must be established in a Member State or associated country, and no two of which may be established in the same Member State or associated country”.
- 3.
All estimations are carried out using “BPNet”, which is an extension of the PNet programme (Wang et al. 2006) and bases on MCMCMLE technique.
- 4.
Convergence is measured by t-ratios calculated to check whether the estimate of the parameter vector is capable of producing a graph distribution centered at the observed network (Wang et al. 2009). Snijders (2002) suggests that if the absolute value of t-values for all local configurations (|t Q |) are less than or equal to 0.1 convergence is excellent; if 0.1 < |t Q | ≤ 0.2, it is good, else if 0.2 < |t Q | ≤ 0.3 convergence is fair.
