Information economics originated in the 40s, developed in the 50s and 60s, and basically matured by the 70s. In the early days of its establishment, there were various research priorities, some scholars focused on basic theoretical research, while others focused on applied research, and it was the mutual complementarity and mutual promotion of these two types of research that laid the theoretical foundation of information economics. After entering the 70s, the development of information economics has basically reached maturity, which is marked by the emergence of a large number of treatises on information economy, such as:

Horowitz in the United States, Wilkinson in the United Kingdom, Wilkinson in the United Kingdom, and Yoshiji Soda in Japan, etc.
