She opened the match by taking more than 70 percent of the points in the first set, allowing Arruabarrena only four points in three games serving.
Pavlyuchenkova also won in straight sets but it was a very different match as she battled Francesca Schiavone for 2 hours, 23 minutes before claiming a 7-6 (13-11), 7-6 (8-6) victory.
Each player managed just one break and Pavlyuchenkova had only a 101-97 advantage in total points.
It was the third consecutive lengthy match for Schiavone, who played for 2 hours, 41 minutes in her second-round match and more than 2 hours in the quarterfinals.
Radwanska has reached her fourth WTA title match of 2013, a run that includes two wins in January and a runner-up finish in July in Stanford, Calif. She's 12-7 in her previous title matches.
Pavlyuchenkova is 5-2 in finals, with two wins in three championship appearances this year.
Radwanska has won two of her three matches against Pavlyuchenkova. Radwanska won in the third round of the U.S. Open in their most recent meeting.
The KDB Korea Open champion will take home more than $112,000 with the runner-up winning about $56,000. Arruabarrena and Schiavone each earned $29,000 as semifinalists.
