This article reviews the cooperative accomplishments the SCO member states made in trade，investment，finance，etc. in 2014，especially the essential breakthoughs in energy，infrastructural construction，tranport facilitation and finance. The year 2015 is a critical one for the SCO to continue with the past and open up the future，with the will of the member states for cooperation obviously strengthened，and new opportunities provided through the joint construction initiated by China of the Silk Road Economic Zone. In the meantime，however，the member states’ economic growth slows down，the establishment of the Eurasian Economic Union poses challenges to the SCO’s future economic cooperation. In perspective of long-term development of regional economic cooperation，the legal basis of regional economic cooperation should be further consolidated，the cooperative role in market mechnism should be strengthened，and the arrangement to create preferential trade and investment mechanism should be made. From a short-term point of view，the network for infrastructural interconnection and intercommunication to cover the whole region should be built，the area of non-resource cooperation should be expanded，the area of financial collaboration should be deepened，and the cooperative relations with observer and dialogue partner states in economy and trade should be enlarged.
