In 2017，thanks to the steady recovery of the world economy，global trade and investment expansion，as well as commodity price rebound，Latin America and the Caribbean ended its recession in the past two years. The regional economy recovered and major macro indicators like inflation and international payments turned better. The three major regional economies showed different economic performance. The differences in regional growth converged，yet at the expense of the consecutive slowdown in Central America. Against the background of macroeconomic improvement，fiscal policy of all countries in the region targeted fiscal stability. Increasing income and throttling expenditure have become the choice of regional policies. Meanwhile，the elasticity and space of monetary policy grew a little bit，playing a certain role in providing incentives for economic growth. However，in view of international comparison，the rate of regional growth is still low，and the risk of being marginalized is increasing. Looking forward to the future，the regional economy is expected to continue its growth in 2018 under the favorable external circumstances. However，due to the increase of external uncertainties，the regional economy is difficult to achieve a strong rebound in the middle and short term，and the differences in internal growth will continue.
