摘要：

I review the meaning of 'QCD factorization' in hadronic two-body B decays and then discuss recent results of a theoretical (rather than phenomenological) nature: the proof of factorization at two-loops; the identification of 'chirally enhanced' power corrections; and the role of annihilation contributions.
