Chen Ou-po

The Democratic Progressive Party endorsed Chen for a second term in 2015, which he won. Chen contested a September 2016 internal election for secretary-general of the DPP caucus, losing to Liu Shih-fang. He was elected convener of the transportation committee in February 2017, alongside Cheng Pao-ching. By 2017, Chen was considered a potential candidate for the magistracy of Yilan County. However, after Lin Tsung-hsien and Wu Tze-cheng joined the Executive Yuan, the Democratic Progressive Party named Chen Chin-te acting county magistrate. Chen Chin-te declined to run in the 2018 local election, and Chen Ou-po registered for the party primary in January 2018. Hsieh Tsan-hui and Chiang Yung-ho also registered for the magisterial primary, but dropped out a week later. The Democratic Progressive Party formally nominated Chen Ou-po as its candidate for the Yilan County magistracy in March. Lin Tsung-hsien and Chen Chin-te, among others, aided Chen Ou-po's campaign. Following his loss to Lin Zi-miao, Chen remained a sitting legislator, and ran for reelection from Yilan County in the 2020 legislative elections.

He supported the use of nuclear power conditionally, if first approved via referendum. However, in his view, the government remains unable to develop adequate disaster response procedures and waste treatment measures. In April 2014, he and Lin Yi-hsiung protested the scheduled activation of the Longmen Nuclear Power Plant by beginning a hunger strike, during which Chen passed out, necessitating medical treatment. Chen and Tien Chiu-chin attended the National Energy Conference in January 2015 and led a group of 200 protestors. Later that year, Chen suggested that Taiwan's nuclear waste be stored in the United States. In August 2017, Chen stated that Taiwan should invest more in geothermal energy, three years after hosting a public hearing on the topic.

Chen said in September 2013, "It's up to the people of Taiwan to save this country. We should stand up with our determined voice to let the world know that Taiwan belongs in the UN."

Chen was first elected to the Legislative Yuan in 2012. Soon after taking office, he proposed that the legislature move to Dazhi, in Zhongshan District, Taipei. In 2014, he went to the funeral of Chin Hou-hsiu, President Ma Ying-jeou's mother, despite not receiving an invitation. He later apologized. The Democratic Progressive Party legislative caucus barred him from party activities within the legislature for six months. Additionally, he was referred to the legislature's discipline committee. Business magnate Terry Gou offered to fund a recall campaign against Chen.

Commenting on the workforce in 2012, Chen advocated for the government to raise unemployment benefits and employment subsidies. Additionally, he repeatedly drew attention to the rising costs of utilities. Chen opposed the implementation of supplementary national health insurance premiums in October 2012, stating that premiums should either be paid based on household income or the standard premiums should increase. During his first legislative term, Chen continually opposed the rising tolls charged for the use of freeways, remarking that the increases were especially harmful to his Yilan constituency. He continued to advocate for improvements to infrastructure serving Yilan throughout his second term, specifically proposing that traffic congestion in Hsuehshan Tunnel be investigated, and that a railway leading to Yilan parallel to the Chiang Wei-shui Memorial Freeway be built. Chen and Lee Kun-tse suggested in March 2017 that an agency be established to probe road incidents.

Regarding Cross-Strait relations, Chen denounced one country, two systems shortly after taking office. He also called attention to China's economic influence on Taiwanese media. In December 2012, Chen criticized Ma Ying-jeou for allowing more Chinese agricultural imports. The next year, Chen chastised several government officials for their inaction as China announced a new air defense identification zone without notifying Taipei.

Chen Ou-po (Chinese: 陳歐珀 ; pinyin: Chén Ōupò ; born 12 October 1962) is a Taiwanese politician. A member of the Democratic Progressive Party, he has served in the Legislative Yuan since 2012, representing Yilan County.
