Connecting flights from Chongqing International Airport to Beijing.

My flight arrives in CQ from Sydney at 4:45am with a connecting flight departing at 7:30am for Beijing on the same day. Can I catch that connecting flight to Beijing from Jiangbei International Airport or would I have to transit to a domestic airport to get to Beijing, if so is there a shuttle bus & how far away is it. Will I have time to reach in time to board the 7:45am flight.
