Livelihood plays an indispensable role in sustainable community development. Previous studies of sustainable livelihood have focused on the factors that contribute to the vulnerability or resilience of livelihood, but there is limited understanding of the factors that determine people's livelihood restoration after a major disaster. By using a mixed method, combined interviews with questionnaires, this research has quantified the critical factors that influence the livelihood recovery of local communities affected by the Lushan earthquake in 2013, China. The statistical analysis shows that the most highly ranked top four factors are access to income generation assets, external housing recovery support, the level of community participation in decision making, and availability of family support. Factor analysis further suggested that the 16 critical factors identified fall into four categories, namely: 1) government policies; 2) access to resources; 3) social cohesion; 4) individual characteristics. For livelihood recovery to be embedded in the longterm sustainable development of earthquake-affected communities in Lushan, it is important to address the sustainable development through a proper knowledge transfer process including training, education, and more novel community services.
