Carbon sink production and carbon sink trade have boosting effect on regional economic growth， especially，bring new ideas and new opportunity to economic and social development in the west regions of China. The research shows that the development of carbon sink production based on forest and grass can accumulate development potential energy and tamp the development of industrial economy，urban and green economy. Carbon sink production and carbon sink trade provide effective initiation and grip for ecological protective screen construction and economic leapfrogging development in west part of China. Currently，the west part of China actively participates in carbon sink production and carbon sink trade but the efficiency is not high，furthermore， its inner development is not balanced. West part of China should pay more attention to ecological and environmental construction，develop forestry and grass， push forward ecological migration， boost part of areas to quit grain production in order，expand new area of carbon sink，tamp regional carbon sink base，promote carbon sink efficiency，set up more ecological special zones，implement special policies for ecological construction and ecological protection，ecological compensation and transfer payment as well as financial policy and political performance examination policy，take the advantage of carbon sink and environmental capacity to accept heavy and chemical industry from east part of China，develop green economy，try to get vertical ecological transfer payment from central government and horizontal ecological compensation and boost carbon sink capacity construction.
