Theorizing Actor Interactions Shaping Innovation in Digital Infrastructures: The Case of Residential Internet Development in Belarus

This paper focuses on how digital innovation develops in ecologies of distributed heterogeneous actors with contesting logics, diverse technologies, and various forms of orchestrations. Drawing on the insights from emerging theories of digital innovation augmented by an institutional logics perspective, we examine a case study of how residential internet infrastructure was shaped over 20 years by the interplay of self-organized residential communities, corporate internet service providers (ISPs), and a state ISP. Our analysis of this case leads to the identification of four types of interactions that shape the trajectories of digital infrastructure development beyond direct actor interplays and competitive or collaborative relationships. We label these interactions symbiotic generative, symbiotic mutualistic, parasitic complementary, and parasitic competitive and explain the processes and conditions of their development and their innovation outcomes. Drawing on these findings, we develop a model of symbiotic and parasitic interactions shaping digital infrastructure development and identify key characteristics of the ecologies where these emerge. The case study and the model that emerged aim to contribute to the growing field of research on complex and nonlinear paths of digital innovation development constituted by the dynamics of its distributed agency. The article concludes by highlighting avenues for future research.
