The evolution of the global digital platform economy: 1971–2021

Some years, like some poets and politicians, are singled out for fame far beyond the common lot and 1971 was clearly such a year. One of the events of 1971 was the inventions of the microprocessor, a computer on a chip. This invention led to the creation of the personal computer, the internet, the smart phone, and cloud computing. Over the past 50 years, economic activities have been reorganized from large bureaucratic firms to a more networked form of organization for creating value for consumers and making money for companies. To further our understanding of this digital revolution, we provide a framework consisting of three interrelated concepts: digital technology infrastructure, multi-sided digital platforms, and platform-based ecosystems. Using a unique database over five decades, we test the hypothesis that new firms were needed to introduce digital technologies. Countries that did not promote new firms fell behind in adopting the new technologies.
