英國於1973年正式加入歐洲統合而成爲歐體會員國，至2016年6月23日公投決定脫歐，身為歐盟第二大經濟國，43年的關係已確定要分手。 歐盟經濟和社會政策的核心總結起來為四大自由-包括商品、資金、人員及服務，因此歐元及申根條約為其支柱，可是自歐債危機、敘利亞難民以及恐怖攻擊後，頓時令這兩大支柱受到挑戰，多種因素讓英國認為與歐盟的統合已經走到「弊大於利」，因此選擇說再見的時候。 本研究循歷史發展探討英國與歐盟間之競合，並以互賴理論，自英國加入歐盟之利益考量，脫歐公投之背景及分析脫歐派與留歐派雙方之立場，就經貿、就業機會、會費預算、歐債危機、移民、邊境管控等面向分析，以及脫歐後對於英國及歐盟之影響。也因歐盟「中央集權化」的趨勢下，英國認為對於法規、財政治理、移民管控自主權的喪失，而以拿回主權為訴求。 自英國決定脫歐後，英國首相梅伊(Theresa Mary May)於今(2017)年也已提出了脫歐計畫白皮書，闡明將完全的脫離歐盟，日後雙方的談判仍是漫長艱難。 從英國脫歐到川普當選都顯示出反全球化思潮、種族民族主義、反對向歐盟等超國家組織讓渡主權，此股風潮正在改變歐美政治，因此期藉由本研究，能初探其原因。 / In 1973, the United Kingdom officially joined European integration and became a member of the European Community. In June 23, 2016, the United Kingdom held a public vote for Brexit and decided to leave the European Union (EU). As the second largest economy in the EU, the United Kingdom is determined to terminate the 43-year relationship with the EU. The EU economic and social policy core contents comprise four basic freedoms, namely, goods, capital, people, and services. Euro and the Schengen Agreement are the two pillars supporting the EU. However, the European debt crisis, Syrian refugees, and terrorist attacks have affected the stability of the two pillars. Various factors cause British people to believe that it is unworthy of continuing European integration because the United Kingdom benefits from the EU at a cost of losing more. This study investigates the history of coopetition between the United Kingdom and the EU and uses interdependence theory to analyse the economic consideration of the United Kingdom to join the EU, the context of the Brexit vote, and the viewpoints of advocates and opposition for remaining in the EU. We also analyse different dimensions, including trade, job opportunity, the EU membership fee, European debt crisis, immigrants, and border control, as well as the effect of Breixt on both the UK itself and the EU. In addition, because of the centralization trend of the EU, the United Kingdom claims to retrieve the losing autonomy of legal regulation, fiscal governance, and immigration control. After the decision of leaving the EU was determined, the UK Prime Minister Theresa Mary May proposed a Brexit White Paper in 2017, declaring that the United Kingdom will leave the EU completely. Long and complicated negotiations between the United Kingdom and the EU are expected. From the Brexit issue to Trump elected as the US president, these events reveal a trend of antiglobalisation, ethnic nationalism, and refusal to yield sovereignty to supranational organisations such as the EU. This trend is changing the politics in the Europe and the United States; thus, the present study is conducted to preliminarily identify the rationale behind this trend.

2016年的英國脫歐公投，最終以51.89%比48.11%的差距，決定了英國脫歐的命運。各界紛紛揣測各種可能造成民眾投下脫歐一票的原因，包含個人經濟狀況、政黨認同、受民粹操控、反菁英、對歐洲認同等。本文針對既有研究中尚存在之空缺，聚焦「議題投票取向」對選民投票抉擇的影響，探究脫歐陣營對資訊的扭曲是否對選民的投票抉擇有顯著影響。論文就脫歐派針對國民健保、移民、脫歐後的英國對外經貿、失業率、勞工權益保障與是否能無條件持續享有歐盟單一市場好處這六項議題，透過「二分勝算對數模型」進行分析，從個體層次行為來瞭解資訊扭曲對選民在脫歐公投中投票行為的影響。 研究結果顯示，在移民潮來襲、民眾高喊反全球化與選民不安全感高漲的大環境背景下，脫歐陣營對選民所關心之議題的煽動與對資訊的操控使選民在做出投票抉擇時受到明顯誤導。此外，模型結果亦顯示，選民的個人社經背景與心理態度認知同樣對選民投票行為產生影響。總結而言，本研究透過微觀層次的分析，針對促使選民投下脫歐一票的因素做出深入探討，並以「資訊扭曲」作為重要變數，補充議題投票相關研究之不足。 / In the Brexit referendum held in June 2016, 51.89 per cent of the voter voted Leave and 48.11 per cent voted Remain. The result sealed the fate of the UK as an outsider of the European Union. While the reasons behind voter’s choice to leave the EU remain disputed, individual voter’s socio-economic status, party identification, populism, anti-elite mood, and identity toward European were among the most frequently listed factors. In order to fill the gap that existing researchs has left, this thesis focuses on the significance of “issue voting” in voting behavior. It discusses if the distortion of information by the Leave campaign had a significant impact on people’s voting choice. It uses the “logistic regression model” to analyse six issues brought about by the Leave campaign. They include the NHS, immigration, trading arrangements with other nations, unemployment, working conditions for British workers, and unconditional maintaining of all the benefits from the EU. By focusing on the individual level, I try to investigate how the distortion of information has impacted upon people’s voting behavior in the Brexit referendum. The study shows that against the background of an increased flow of immigrants and heightened anti-globalization mood, voters had a strong sense of insecurity. Under such circumstances, the Leave campaign exploited the opportunity to incite voters on issues they cared most about, manipulated information during the demagogic campaign, and misled people on their voting decision. In addition, the model also demonstrates that voters’ socioeconomic status and mental cognizance have the same effect on people’s voting behavior. In the nutshell, this thesis uses micro-level analysis to investigate voter behavior in the Brexit referendum. It brings in “information distortion” as a key variable in explaining voter behavior, a variable largely neglected in the existing literature on issue voting.
