This paper focuses on elaborating the characteristics of the SCO’s regional economic cooperation in 2013：Regional economic cooperation continues the steady tendency of development，the rate of trade grown slows down，investment increases significantly，and the facilitation of trade investement uninterruptedly pushes on. The speed of economic growth will slow down in all the countries in the future regardless of regional security factors，the customs union in particular will restrict the process of regional ecnomic cooperation，but the building of the Silk Road Economic Zone will provide new opportunities for member states to consolidate trade and business between themselves. Generally speaking，regional economic cooperation has entered a period of adjustment. New dynamics will be injected into regional economic cooperation by furthering facilitaion of trade investment，and expanding mutual trade and regional investment so that favorable conditions can be created for all the relevant countries to extricate themselves out of the depression.
