After losing her opening three service games, Kvitova won five straight games to take the opening set.
Kvitova carried the momentum into the second and dispatched the fourth-seeded Ukrainian in 1 hour, 10 minutes to claim her 19th career title.
The result completed a dominant week for Kvitova, who dropped just 18 games in her four matches.
Kvitova has reached six finals in the WTA's Asian swing, winning in Wuhan and Zhuhai.
