Relocation of professional sports teams occurs when a team owner moves a team, generally from one metropolitan area to another, but occasionally between municipalities in the same conurbation.
Team moves in China are very common, as teams are privately owned or owned by businesses, and there are neither rules regarding moves nor many established fan bases outside of the handful of established top teams.
China, although has a European style promotion and relegation league system, the teams themselves are North American-style franchises which means the teams are overwhelmingly privately owned and therefore favour relocation practices.
Owners who move a team generally do so seeking better profits, facilities, fan support, or a combination of these.
