Nowadays various innovative technologies have been adopted by governments worldwide in resolving various complex and grand societal challenges. We have reported an in-depth case study, which has elaborated how a Chinese metro company has governed the risks of adopting an innovative technology, mobile payment. We have identified three primary risks involved in adopting mobile payment technology, namely promotion risk, integration risk, and organizational risk. For the governance of the risks involved, three different governance strategies were adopted by the metro company in Nanjing, namely, no response, control-oriented strategy, and toleration-oriented strategy.
