This paper examines the effect of the newly introduced “one man two votes” electoral system in the 17th National Assembly election in Korea, using survey data.
First of all, the rate of ticket splitting was not significantly high at only 20.8%. The ticketsplit voting behavior of Korean voters in the 17th National Assembly election could be seen as strategic. But strategic calculations were not so strong. Introduction of a new electoral system affected party arrangement. The Democratic Labor Party and the Open Uri Party benefitted, but the Grand National Party and the Democratic Party suffered losses under the newly introduced mixed electoral system. The effect of the introduction of the “one man two votes” electoral system in resolving disproportionality was minimal. The introduction of “one man two votes” electoral system neither systematically affected the voting turnout nor mitigated the traditional regionally based voting behavior of Korean voters.
