报告摘要：
Hadronic B-meson decays play an important role in testing the Kobayashi-Maskawa mechanism of quark-flavor mixing and CP violation. Thanks to the successful running of BaBar, Belle, LHCb and Belle II experiments, we are now entering an era of precision flavor physics. In this talk, I will review the status of NNLO perturbative QCD corrections to two-body hadronic B-meson decays in the framework of QCD factorization approach, or its field-theoretical formulation within the soft-collinear effective theory. After introducing briefly the theoretical framework for hadronic B-meson decays, I will present the calculations of these higher-order perturbative QCD corrections, firstly to the tree and then to the leading QCD penguin amplitudes. With these NNLO corrections included, phenomenological analyses of the tree- and penguin-dominated two-body charmless B-meson decays, as well as the class-I B-meson decays into heavy-light final states are given. Possible higher-order power corrections motivated by the current data will also be discussed.
