In this monography we were interested in the interconnection between so called Shared Economy and the Industry 4.0 approach. We have proven that the sh. ec. is one of the resulting effect of the I4.0. More we provide the case study of the most attracted sh. ec. application in the Czech Rep., the Airbnb approach. For many traditional accommodation services the ordinary flats supplied through AIB. are the illegal activities which ban their legal business. Thank to regression and correlation analysis, we confirm, that in the Czech Rep. the increase in the AIB. overnight stayed in Prague is interconnected with the increase in services sold by the traditional accom. suppliers in concretized structure. The main hypothesis of this book is confirmed, the sh. ec. is the resulting effect of the I4.0 approach. The shared ec. AIB. application attend to new segment in economy. And makes no harm to traditional suppliers. The sh. ec. applications should be legalized. These applications are the same effects as the technological shifts made many times before (steam, combustion engine, electricity etc.). This technolog. shift for the shared economy was the internet initialization.
