Despite the internet revolution, economic growth in many industrialized countries (measured in real gross domestic product) has been significantly lower in recent years than in previous decades. This may be due to the fact that the growth effects are not measured correctly, but also because significant growth potential has not yet materialised. According to its underlying logic, GDP is a measure of the industrial age. Measurement problems in an increasingly service-based and knowledge-based economy are well known, although many of them have not yet been adequately addressed in national accounts. The digital transformation is amplifying these difficulties.The aim of the study is to develop an approach and to provide first empirical evidence for the extent to which gross domestic product measurement in Germany could be extended and expanded to include previously unmeasured aspects of the digital economy. Furthermore, the current and future growth potential of digital transformation will be estimated.
