Network studies aim to examine relationships between companies, and broadly analyze the structure of networks. The overtime dynamics of networking process, however, remain underexplored. The aims of this study are to explore main network research streams by identifying characteristics and measures of networks and to examine how the content of networks changes through different stages of the company creation process (motivation), planning and establishment. The goal is to incorporate networks into the international entrepreneurship literature and discuss a framework for network dynamics in the firms’ creation process. In this chapter we draw a model of main network research perspectives, analyze the characteristics and the measurements of networks, and review the literature of network dynamics. Finally, we generate four propositions from theoretical discussion concerning change by showing that networks do not remain static, which should serve to guide us toward future empirical research.
