Executive SummaryServices are simultaneously the most important sector of the UK economy and the sector facing the biggest challenge as a result of Brexit. The prospective departure from the European Single Market reduces the UK to the status of ‘3rd country’ in respect of services. Accessing the internal market will depend on both subjective and objective conditions that differ from sector to sector, requiring detailed and highly specific arrangements for such industries as aviation and financial services.In practice, the EU can be expected to use these circumstances to discourage the UK from significantly diverging from European regulatory norms, as a matter of policy. In view of the weakness of, and uncertainty surrounding, international moves to oversee, let alone to further liberalise, trade in services, Brexit will thus leave the UK's services sector – and especially financial services – uniquely isolated and exposed. The government will hence need to consider carefully the costs of decisions to diverge from EU regulatory standards, and should be giving great priority to establishing clear objectives for close cooperation between the UK and the EU policy makers and regulators.

发展服务贸易

执行摘要服务业同时是英国经济中最重要的部门，也是因英国退欧而面临最大挑战的部门。退出欧洲单一市场的预期将英国降低到服务方面的“第三国”地位。进入内部市场将取决于不同行业的主观和客观条件，需要对航空和金融服务等行业做出详细和高度具体的安排。在实践中，可以预期欧盟会利用这些情况来阻止英国作为政策问题，与欧洲监管规范显着不同。鉴于监督服务贸易的国际行动的弱点和不确定性，更不用说进一步开放服务贸易，英国脱欧将因此离开英国。服务业——尤其是金融服务业——独特地孤立和暴露。因此，政府将需要仔细考虑偏离欧盟监管标准的决策成本，并应高度重视为英国与欧盟政策制定者和监管机构之间的密切合作建立明确的目标。
