Oxford University recently released a new report "Real Estate Technology 2020-The Future of Real Estate". Proptech (Real Estate Technology) describes the digital transformation that is currently taking place in the real estate industry. The Proptech 1.0 wave originated from the PC of the 1980s and the rise of the Internet in the 1990s, ending with the bursting of the Internet bubble in 2001. Proptech 2.0 was stimulated by GFC and technological development, and finally reached its peak in the App Store, with signs that it is now maturing. Proptech 3.0 will be driven by the pressure of global climate change and rapid urbanization, and will be achieved through the maturity of exogenous technologies such as the Internet of Things, machine learning and artificial intelligence, and blockchain.
