This study investigates the complementary roles of network and identity in the spatial diffusion of linguistic innovation, using an agent-based model validated against Twitter data. The findings reveal that network effects primarily drive spread in urban areas via weak-tie diffusion, while identity effects dominate in rural areas through strong-tie diffusion. Diffusion between urban and rural areas necessitates both network and identity.
