Digital Transformation and Intellectual Capital of Telecommunications Companies: An Econometric Assessment of the Impact on Operational Efficiency

This paper discusses how digital transformation and intellectual capital interact to affect the performance of telecommunications firms in a fast-changing digital world. The research problem is based on the lack of integration of these factors into a single empirical framework, in particular, cross-country settings with different degrees of digital maturity. This study offers an econometric evaluation of the relationships in detail using panel data of telecommunications companies in Ukraine, Germany, Poland, and Estonia during the period 2021-2025. The methodological approach based on panel data econometric model that incorporates both fixed and random effects, and an interaction term to capture the synergistic relationship between digital transformation and intellectual capital. The most important variables are a Digital Transformation Index, and the elements of intellectual capital, human, structural, and relational, and a list of control variables, including firm size, leverage, and macroeconomic conditions. Strong standard errors and diagnostic tests are used to assure the validity and reliability of the estimates. The empirical findings indicate that the positive and statistically significant impact of digital transformation on the operational efficiency is positive and statistically significant (coefficients of 0.198 to 0.284).
