At present，domestic and foreign studies on the timing and method for induction of labour in twin pregnancy are very limited and controversial. This article discusses the implementation of induction by the evaluation of effectiveness and safety，the selection of timing and method and the management of intrapartum in twin pregnancy in order to provide the basis for the standardized management of vaginal delivery in twin pregnancy.
