In 2017，the EU's economy fully recovered and the growth rate of the euro zone reached its fastest pace in ten years. In terms of the internal governance of the EU，the measures controlling the member countries' fiscal deficits and government debt have produced initial results，the reform of the labor market made breakthroughs，and the unemployment rate in both the EU and the euro zone declined continuously. In the trade area，along with a substantial pickup of the EU's external trade in 2017，the rising of the internal trade volume within the EU has reached such a degree as to make the intra-trade share at the highest level in a decade. The EU's OFDI（Outward Foreign Direct Investment）has been falling year by year，indicating its declining enthusiasm for investment abroad. The EU is nevertheless one of the most important destinations in attracting foreign direct investment and the world share of the EU in terms of foreign capital utilization has increased significantly in recent years. However，due to the lack of sufficient driving factors for economic growth，it remains to be seen whether the overall economic recovery is sustainable in the EU in 2018，especially that a comprehensive vision of the systemic risk of internal governance has been changed to a partial one，quantitative easing policy reached what has been expected，the pressure is on the rise for the maturity structure，and the raising by the US Federal Reserve of interest rate indicates that the European Central Bank's tightening of monetary policy is forthcoming.
