...the most expensive areas in Beijing to rent a room or apartment are Dongcheng and Shunyi, which have seen a 10.5 percent and 10.7 percent rent increase...
I'm not sure why you've used this wording now in two articles... the highest *increase* does not mean the highest price. For example, 3000 increasing by 20 percent to 3600 is still less than 4000 increasing by 10 percent to 4400. This should be obvious because Shunyi is nowhere close to the most expensive place to rent in Beijing.
Thanks for your comment. You're quite right, and we've amended the wording accordingly.
