Abstract: The term "Andersstreben" means that a type of medium seeks to imitate the features of another type while keeping its own characteristics. In terms of narrative, "Andersstreben" means cross-media narrative. Regarding fiction that features cross-media narratives, we need to understand both its own medium particularities and the other media properties that it pursues. Only in this way can we better appreciate its aesthetics. Cross-media narratives primarily originate from the mutual imitations between temporal arts and spatial arts, and often achieve magical artistic effects and rich artistic connotations that are otherwise unattainable for literature and arts by simply sticking to their own media. "Andersstreben" and its corresponding cross-media narratives constitute the "common factors" and theoretical bases for comparative studies between literature and other forms of art. In fact, spatial narrative in fiction is also a typical cross-media narrative.

Key words: Andersstreben, imitation, cross-media narrative, spatial narrative, internal research
