This document summarizes research on mergers in Chinese higher education. It describes two waves of mergers that occurred in the 1950s and from the 1990s onward. The motivations and characteristics of recent mergers are discussed, including classification systems. Outcomes like rankings, economics of scale, and academic performance are addressed. Key lessons are that mergers don't guarantee success and proper planning, funding, and staff integration are important. While mergers helped some universities, cooperation may be a better future direction for Chinese higher education.
