摘要
Drawing on a twelve-month concurrent mixed-methods design that combined a cross-sectional survey(N=1,240),14.8 million platform-level digital-trace observations,and a randomized field intervention,this study examines the extent towhich international student mobility reshapes civic participation and public-governance dynamics.The analysis identifies threemajor patterns.First,multilevel regression models show that every additional year spent abroad is associated with a 0.27-pointincrease(SE=0.04)in a five-point hybrid-engagement index,controlling for socioeconomic background,language proficiency,and prior civic exposure.Second,difference-in-differences estimation reveals that a policy-literacy workshop raised the odds offormal volunteering by 42%(OR=1.42,95%CI 1.28-1.57)and boosted perceived municipal responsiveness by 0.34 SD.Finally,network analytics demonstrate that workshop participants expanded the transnational density of their online governancenetworks by 18.9%while simultaneously reinforcing local bridging ties,suggesting a dual anchoring of engagement.Thefindings illuminate how cross-border education catalyzes novel,layered forms of civic involvement and exposes blind spots inrepresentation and service delivery,offering concrete design principles for host-city institutions intent on leveraging studentvoices for participatory governance reforms.
