This study constructed a model of blockchain specialty identity using structural equation modelling by randomly sampling students from a higher vocational college and analyzed the role relationship and influence effect of each element in the model. The findings show that specialty emotion, specialty behavior, specialty goal, and specialty awareness all have a direct positive influence on blockchain specialty identity. Among these factors, specialty behavior has the greatest influence, followed by specialty emotion. Therefore, this study verifies the conclusions of scholar BrickSon's research related to college students' specialty identity and provides a theoretical basis for the construction and talent cultivation of blockchain technology application majors.
