The ruling Democratic Party of Korea secured a majority of regional executive positions and parliamentary by-election seats, although the People Power Party retained control of the Seoul mayoralty.

執政的共同民主黨贏得多數區域行政職位及國會補選議席，但國民力量黨仍保有首爾市長之控制權。

The electoral results indicate a divergent political trajectory between national and municipal governance. The Democratic Party achieved a quantitative victory, securing 12 of 16 mayoral and gubernatorial posts and nine of 14 parliamentary by-election seats. This outcome is attributed to the robust approval ratings of President Lee Jae Myung, which exceed 60 percent, and a general public preference for his pragmatic diplomatic approach and government transparency. Notably, Choo Mi-ae became the first woman to lead a provincial government upon her election as Governor of Gyeonggi Province.

選舉結果顯示，國家層面與市政管理之間的政治軌跡呈現分歧。共同民主黨取得了數量上的勝利，贏得16個市長與省長職位中的12個，以及14個國會補選議席中的9個。此結果歸因於總統李在明超過60%的高支持率，以及大眾對其務實外交手段與政府透明度的普遍偏好。值得注意的是，秋美愛在當選京畿道知事後，成為首位領導省級政府的女性。

Conversely, the Seoul mayoral contest resulted in the reelection of Oh Se-hoon, who secured a historic fifth term with 49.15 percent of the vote. Analysts suggest this result was driven by 'patrimonial voting,' wherein residents of high-value real estate districts prioritized the protection of property assets over national political trends. Furthermore, Oh's strategic distancing from the pro-Yoon Suk Yeol faction of the People Power Party (PPP) is cited as a critical factor in attracting centrist voters. This victory provides a degree of institutional stability for the PPP, despite its loss of control in Busan and Ulsan, signaling a potential erosion of its traditional Yeongnam stronghold.

相反地，首爾市長之爭結果由吳世勳連任，他以49.15%的得票率贏得了歷史性的第五任期。分析師指出，此結果是由「家產式投票」驅動，即高價值房地產區域的居民優先考慮保護資產，而非追隨國家政治趨勢。此外，吳世勳策略性地與國民力量黨（PPP）內親尹錫悅派系保持距離，被視為吸引中間選民的關鍵因素。儘管國民力量黨在釜山與蔚山失去控制權，預示其傳統的嶺南根據地可能遭到侵蝕，但此次勝利為該黨提供了一定程度的制度穩定性。

Administrative irregularities further complicated the electoral process. The National Election Commission (NEC) acknowledged a ballot shortage at 14 polling stations in Seoul, primarily in conservative-leaning districts such as Songpa-gu. This failure precipitated civil unrest, including the physical obstruction of ballot transfers and demands for a total nullification of the results. While the PPP initially sought a rerun, the NEC maintained that such shortages do not constitute legal grounds for invalidating an election under the Public Official Election Act. Additionally, the election of 11 progressive education superintendents suggests a continued shift toward liberal pedagogical policies nationwide.

行政失誤使選舉過程更趨複雜。國家選舉委員會（NEC）承認首爾有14個投票站出現選票短缺，主要集中在如松坡區等傾向保守的區域。此次失誤引發社會動盪，包括肢體阻攔選票運送以及要求全面廢止結果。雖然國民力量黨最初尋求重新投票，但國家選舉委員會維持原判，認為根據《公職選舉法》，此類短缺並不構成廢止選舉的法律依據。此外，11位進步派教育長的當選，顯示全國教育政策正持續向自由主義轉型。

The elections have reinforced the Democratic Party's legislative and regional dominance while establishing the Seoul mayoralty as a conservative counterweight.

此次選舉強化了共同民主黨在立法與地區的主導地位，同時將首爾市長之職確立為保守派的制衡力量。
