This book analyzes the business model of enterprises in the digital
economy by taking an economic and comparative perspective. The aim of
this book is to conduct an in-depth analysis of the anti-competitive
behavior of companies who monopolize data, and put forward the necessity
of regulating data monopoly by exploring the causes and characteristics
of their anti-competitive behavior. It studies four aspects of the
differences between data monopoly and traditional monopolistic behavior,
namely defining the relevant market for data monopolies, the entry
barrier, the problem of determining the dominant position of data
monopoly, and the influence on consumer welfare. It points out the
limitations of traditional regulatory tools and discusses how new
regulatory methods could be developed within the competition legal
framework to restrict data monopolies. It proposes how economic
analytical tools used in traditional anti-monopoly law are facing
challenges and how competition enforcement agencies could adjust
regulatory methods to deal with new anti-competitive behavior by data
monopolies.
