“…Firstly, traditional cluster studies mainly focus on what happens within a cluster itself, such as a geographically spatial perspective (e.g., Maurseth & Frank, 2009;Zhao, 2003), cluster strategies (e.g., Waits, 2000), innovative ability of clusters (e.g., Baptista, 2000;Simmie, 2004), labour mobility of clusters (e.g., Gittelman, 2006;Power & Lundmark, 2004), and so on. In contrast, this paper investigates the relations among clusters, which is a new way of analyzing cluster phenomena.…”
