By claiming a first prize of over £720,000 the Swede has also given himself a chance to deny McIlroy the same European and PGA Tour money list double achieved by Luke Donald last season.
With four more weeks to go he leaps from seventh to second in the standings, and although the Holywood player's runner-up finish means he still has a lead of more than £650,000- the winner's cheque is more than that in this week's World Championship event at Mission Hills in Shenzhen, which McIlroy is not playing.
"I'm going to try to keep this form going," Hanson said after a closing bogey gave him a one-stroke victory after both of the front two shot five-under-par rounds of 67.
The world number one golfer admitted he was a little disappointed by the result but was happy overall with how he played.
"I missed a few opportunities on the front nine and it was too little, too late," he said.
I wanted to make him work for it and it would have been nice to hole the putt on the last, but it wasn't to be and Peter deserved it.
Hanson was five clear after a hat-trick of birdies from the 11th, but McIlroy also made four on the long 13th, eagled the 15th from 18 feet - Hanson birdied - and then cut the difference to two with a five-foot putt at the next.
World number 25 Hanson's par save from 15 feet preserved the gap, but there was still a possibility of a play-off when Hanson's approach to the 471-yard last came down in rough above a bunker.
He thought he might be entitled to a free drop because of a plugged lie, but was refused it and after doing well to chip to 10 feet he breathed a sigh of relief when McIlroy's 15-foot birdie attempt just missed.
That left Hanson with two putts for his sixth European Tour win- the last came with a closing eagle in Holland last month- and he took them.
"Rory made a tremendous effort and put quite a bit of pressure on me - his second to the 15th was true class," Hanson added.
"He gave me a bit of a cushion early on (McIlroy missed two four-foot par putts) and I was maybe a little too defensive at the end, but it all worked out.
"My short game used to be my weak part, but I've been working on it and my putting has really improved."
McIlroy will stay in China for a one-day head-to-head against Tiger Woods- joint fourth in Malaysia after a closing 63.
He will then return to Asia for the Singapore Open and to defend the Hong Kong Open, which will give him the opportunity to clinch the money list before the season-ending World Tour Championship in Dubai.
Luke Donald followed McIlroy in third and Ian Poulter came in fourth.
Justin Rose tied for sixth, Martin Kaymer and Graeme McDowell were joint 11th and Lee Westwood and Nicolas Colsaerts finished in joint 14th.
