Spatial Diffusion of Digital Innovations: Trends, Problems and Prospects of Empirical Research

Abstract

The aim of the study was to generalize the world experience of studying the spatial diffusion of digital innovations in order to determine trends in changing priorities, existing problems and possible prospects for empirical research. With the help of the author’s semantic search algorithm, approximately eighty journal articles published in the last twenty years were found in eight bibliographic databases. The use of a moving average and biproportional indices for quantitative analysis of the array of articles revealed four upward trends: an increase in the average annual number of publications on the subject under consideration, increased attention to the deployment of broadband communications, the impact of spatial diffusion on economic growth and the use of regions as territorial units for studying diffusion processes. An informal analysis of the articles led to the identification of five key problems of modern research: a significant discrepancy between the year of publication and the last year of the process under study, analysis of a limited number of digital innovations, lack of a comprehensive understanding of the joint spatial diffusion of several innovations, the dominance of the idea of the homogeneity for the initial territorial units and the unexplored system of factors contributing to or hindering the spread of digital innovations. Comparing the existing experience of studying the spatial diffusion of digital innovations with similar studies of other types of innovations allowed identifying five promising areas for further research: the use of big data; expanding the set of models used with the subsequent creation of a system of methods; the study of hierarchical, network and other methods of spatial diffusion; the definition of spatial innovation waves with an explanation of the reasons for the formation of territorial barriers and filters; creation of a theory of the spatiotemporal spread of digital innovations based on the generalization of empirical research. The necessity of determining the scope of application of the results obtained in diffusion studies outside of regional economic policy is noted
