Although collective action relating to land and environmental disputes in Vietnam has been increasing over the past decades, there is little research from the perspective of social psychology on this topic.


This study was conducted to examine the applicability of the social identity model of collective action [SIMCA] in the context of Vietnam. Specifically, we assessed the predictive powers of moral conviction, politicized identity, group-based anger, and group efficacy on people’s intentions to engage in collective action in a situation where people from three communes of Hanoi blocked garbage trucks to enter a waste treatment complex located in this area.


The participants were 132 residents from these communes. We collected the data by a self-report survey and then executed regression and path analyses to test our hypotheses.

Results and Discussion:

The results indicated that, except for group efficacy, variables in SIMCA were capable of independently predicting intentions to participate in collective action. Also, politicized identity had directly and indirectly positive effects on collective action intentions through group-based anger but not group efficacy. Politicized identity and group-based anger played partial mediating roles in the relationship between moral conviction and collective action intentions.


These findings partly supporting the proposed SIMCA demonstrated the impacts of Vietnam's unique cultural and political characteristics on individuals' engagement in collective action relating to land and environmental disputes between people and their local authorities.
