A dominant week, in which she did not drop a set, was rounded off in style as Radwanska closed out a 6-4, 6-2 victory in an hour and 36 minutes.
Radwanska advanced to the final without dropping a set and early on she looked primed for another routine outing. However, from 5-2 down Konta finally began to display the sort of tennis that upset Madison Keys in the previous round.
She reduced her arrears to 5-4 and even had an opportunity to draw level. This proved to be the turning point, as Konta missed a routine drive volley and a few points later saw the set finally slip away.
The No.3 seed rammed home her advantage at the start of the second, planting a backhand onto the baseline to break in the third game. Konta battled away to the last but was unable to find a way through Radwanska's defenses. The Pole would finish with just eight unforced errors, wrapping up victory with an ace out wide.
Asia has been a happy hunting ground for Radwanska, winning nine of her 20 career titles there. However, her success in Beijing, where she also triumphed in 2011, is of particular significance: "It's a very special moment; third final and second title here. It was a really special week for me and it couldn't be any better."
"Every title means a lot, but especially here when you play against the best players in the world, in one of the biggest tournaments. It's top players from the first round and I've been playing my best tennis all week so of course I'm very happy to win this tournament again, and this trophy is going to stay in a very special place."
Radwanska becomes one of four active players to collect three or more Premier Mandatory titles, joining Serena Williams, Maria Sharapova and Victoria Azarenka. Konta, meanwhile, was appearing in her very first final at this level and the disappointment will be tempered by the knowledge that on Monday she will become only the fourth British player to reach the Top 10.
"It's pretty cool! I'm very pleased with my progress over the past few years and hopefully many more places to climb," Konta said. "I'm just working hard towards playing matches like these, against players like Agnieszka."
An even grander stage could await. Konta's run to the final sees her edge ahead of Dominika Cibulkova and into the final qualifying berth for the BNP Paribas WTA Finals Singapore presented by SC Global.
