An Anatomy of Bengaluru's ICT Cluster: A Community Detection Approach
使用社区检测方法分析2015-2017年班加罗尔ICT集群的企业间网络，发现企业主要与技术相似的公司建立横向知识联系，形成多个技术社区，而跨越社区的企业更可能进行激进创新。
ABSTRACT We use community detection analysis to investigate the structure of Bengaluru's ICT cluster's inter-organizational network during the period 2015–2017. Building on the knowledge sourcing literature, we conjecture that cluster firms primarily build knowledge-seeking horizontal linkages with technologically similar companies, and that this splits the network into multiple technological communities within which firms are tightly connected, but between which linkages are scarce. We further propose that community-spanning firms which build horizontal linkages that bridge technological communities are more likely to conduct radical innovation than their peers. We finally argue that no relation exists between technological proximity and community formation in the network of vertical buyer-supplier relations. Using a voltage-based algorithm for community discovery, we draw empirical support for these predictions. We discuss the implications of our findings for Bengaluru's upgrading potential.
