摘要：Leaving the EU will change the UK's economic relations with the rest of the world. This paper discusses the UK's role in the global economy and the consequences of Brexit for the UK's trade, investment and living standards. We emphasize that international integration encompasses investment and labour services flows as well as trade in goods and services and that there are important interdependencies between the different forms of integration which should be considered when evaluating policy changes. Brexit is likely to make the UK poorer by reducing trade and investment flows, but the size of these effects will depend upon the nature of the UK's post-Brexit economic relations with the EU and the rest of the world. We conclude by considering options for UK-EU relations after Brexit and how the UK should approach future trade negotiations.
