Based on the perspective of consumers, customer loyalty in automotive aftermarket was studied. Customer loyalty was divided into attitude loyalty and behavior loyalty. Structural equation models were established to study these two models separately. Taking enterprise image, switch cost and customer satisfaction as the first-order latent variable, service quality as the second-order latent variable, the influence degree of different latent variables were studied. The effects of same variables on attitude loyalty and behavior loyalty were compared. The results show that the attitude loyalty model and behavior loyalty model are well matched, but in contrast, the behavior loyalty model fits better. The influence of corporate image, service quality and satisfaction on attitude loyalty is greater than that on behavior loyalty, and the influence of switching cost on behavior loyalty is greater than that on attitude loyalty, but the effect is not significantly different.
