摘要	Categorical Enumerative Invariants (CEI) are invariants associated with unital cyclic Apo-categories that are smooth, proper and satisfy the Hodge-to-de-Rham degeneration property. In this paper, we formulate and prove their Morita invariance. In particular, when applied to derived categories of coherent sheaves, this yields new birational invariants of smooth and proper Calabi-Yau 3-folds.
