Industrial heritage tourism reflects the mentality of postmodern nostalgia. Postmodern nostalgia focuses on the "recent past"

and achieves a reconciliation between the past and the present through nostalgic consumption

forming a social mechanism that can make up for regrets. The heritage tourism of state-owned film studios has well explained this social mechanism. In the tourist interaction with Changying Cultural Street

tourists mobilize

beautify and selectively shield the past through experiential nostalgia experience and acquired nostalgia experience

thus achieving self-continuity and identity. In this process

tourists formed a cultural identity of "loftiness"

and participated in cultural reproduction

reshaping their brand awareness of Changying. By constructing the postmodern nostalgia mechanism analysis framework of "postmodern nostalgia experience-cultural identity-cultural reproduction"

the article provides a theoretical basis for enterprises that are still operating to develop industrial heritage tourism.
