The Chinese star made two century breaks en route to securing a 9-5 success in the final in Berlin.
After his victory, Ding told reporters: "It's unbelievable - especially with the Chinese New Year just passing. I love the fans here and this venue.
"I'm a lot more focused in my games now - I've learnt how to take control of frames now. It's made me a lot more confident and hopefully I can win a few more."
Ding has now won four ranking titles this season, a feat that no-one had achieved since Stephen Hendry in 1991.
