Throughout the entrepreneurship literature there is consensus that the network plays a critical role in the entrepreneurial process, as it provides the entrepreneur with access to resources that can facilitate the likelihood of the firm’s emergence and growth. There is also agreement among entrepreneurship scholars of the need to develop a more complete and integrated understanding of network development and change processes. This paper proposes a study of entrepreneurship network development, using survey research to capture data on interrelationships and network structure. The focus is on the transformation of entrepreneurship networks, and how they develop over time. This research addresses an important gap in the entrepreneurship literature, where network relationships and network structure are simultaneously explored, and the dependent variable is the network itself. By drawing on the arguments of Larson and Starr (1993), where the evolution of the entrepreneur’s social network is the outcome of the selection, variation and retention of ties that occurs as the business is established and grows.
