From 2020 to 2021，under the stimulation of extremely loose fiscal and monetary policies，the world economy gradually recovered，coupled with the mitigation of the impact of the epidemic，inflation rose rapidly. The leaders’ climate summit held this year has brought the issue of climate change to a great deal of attention. This paper summarizes three hot issues discussed by global think tanks from October 2020 to September 2021. First，with the relief of the epidemic and the gradual recovery of the economy，global inflation is rising rapidly，and US inflation has exceeded the Fed’s target level for several month. Think tanks mainly study the relationship between inflation expectations，the epidemic，climate change and inflation，and discusses whether this round of inflation needs to be worried. Second，macroeconomic policies in the context of the epidemic. Think-tank studies are mainly concerned with monetary policy，fiscal policy and whether these stimulus policies will lead to financial risks. Third，climate change. Think-tank articles mainly focuses on the impact of climate change on economy and related policy issues.
