“…They have emphasized different aspects of scientific collaboration, including (a) the cognitive/disciplinary factor; for example, the emerging interdisciplinary areas that require collaboration, and so on (Beaver, 2001;Katz & Martin, 1997;Hara, Solomon, Kim, & Sonnenwald, 2003); (b) the geographic factor; for example, researchers who are geographically closer are more likely to collaborate (Katz, 1994;Luukkonen et al, 1992;Schubert & Braun, 1990); (c) the organizational factor; for example, leadership and management of scientific collaboration also play a noticeable role (Finholt & Olson, 1997); (d) the political factor; for example, governments are keen to encourage the level of participation in scientific collaboration (Clarke, 1967;Smith, 1958); (e) the socioeconomic factor (Maglaughlin & Sonnenwald, 2005); (f) resource accessibility (Cohen, 2000); and (g) social networks and personal factors; prestige and productivity of researchers also impact their participation in scientific collaboration (Egghe, Goovaerts, & Kretschmer, 2008;Glänzel, 2000;Glänzel & Schubert, 2001). However, most of the previous studies have either analyzed various possible factors theoretically and qualitatively or verified only an individual factor with quantitative evidences.…”
