2. Key Municipal Policy Battlegrounds

The Banqiao "Twin Domes" Debate

Lee proposes transforming the Banqiao Second Stadium into a modern covered arena ("New Taipei Twin Domes") to anchor economic growth. Su Chiao-hui questions the financial self-sufficiency and severe Banqiao traffic bottlenecks, advocating instead for neighborhood sports centers and distributed community open spaces.

Metropolitan Transit & Highway Congestion

With over 600,000 residents commuting daily into Taipei, transit capacity is vital. Key issues include repairing earthquake damage on the Circular Line, advancing the Sanying Line to Linkou and Taoyuan, and relieving gridlock on Provincial Highway 64/65 and cross-river bridge choke points.

Urban-Suburban Equity & Healthcare Disparity

New Taipei spans 29 diverse districts. Inner urban cores enjoy abundant hospital facilities and rapid transit, while outer coastal (Gongliao, Wanli) and mountainous (Wulai, Pinglin) communities face severe healthcare shortages and aging populations that require mobile clinics and emergency tele-medicine.

Post-Hou Political Succession

The KMT has controlled New Taipei (and former Taipei County) since 2005 (Eric Chu 2010–2018, Hou Yu-ih 2018–2026). The election tests whether Lee can sustain this 16-year fortress of Blue governance or whether Su can leverage her family legacy to reclaim the municipality for the DPP.
