This paper systematically inves-tigates telecommunication industry’s inter-net-and-digitization development situation. Based on existing literature and the unique characteristics of telecommunication industry, we build a comprehensive model to depict the level of intet-and-digitization devel-opment by five key dimensions: market size, informational investment, technological inno-vation, intet application, and intet pene-tration. We propose that this five-dimensional model can capture the key components ofintet-and-digitization development in this digital era. By using Beijing’s telecommuni-cation data, we empirically test our conceptual model and explore the current development level of telecommunication industry’s inter-net-and-digitization progress. Results show that Beijing’s telecommunication industry has great potential in expanding online market size as well as activating technological inno-vation. We also suggest that bigger telecom-munication firms should pay more attention tointet-and-digitization development, espe-cially on intet application and penetration dimensions. Finally, theoretical contributions, managerial implications and future research directions are also discussed.
