Another Chinese Hu Yicheng grabbed silver with 55.790 points, and Kazakhstan's Viktoriya Butolina took bronze with 52.600.
Hu said her confidence grew as the competition progressed.
"In qualifications, I may have felt a bit reserved because it's my first time participating in such a comprehensive competition," Hu said.
"But in the final, it might have been a bit smoother for me and I felt much better."
Japan's Reina Satake, who injured the right ankle during her routine, finished fifth with 11.470.
