Entering the correct Publisher and Editor in a BibTex citation
The label editors refers to human individuals, while the publisher is always a company.
First, the editors: In the context of a book, it only makes sense to talk about 'editors' if the book is an edited volume. Otherwise the people who wrote the book are 'authors'. - - In your case, there do not seem to be any 'editors' at all, but only 'authors' (X.Z., Z.C., and Y.L.). Are you sure that the editors-field is mandatory?
Secondly, the publisher: Formally, yes, the publisher is Elsevier, but if it uses an imprint (here: Academic Press), then you should name the imprint. Do not name the overarching company of the imprint. A publisher can use various imprints in order to circulate books under various trade names (each with different reputations and specificities); to a publisher, the name of the imprint is really one of the main purposes of using an imprint. Therefore, list the imprint (Academic Press), and not the overarching company (Elsevier).
(Why Tsinghua University Press is mentioned in the cover, I do not know; it might have something to do with Elsevier's co-publishing agreement with Tsinghua Univ. Press.)
