Abstract：Considering the carbon emission reduction technology investment and manufacturer's low-carbon promotion under carbon cap and trade， the game models of decentralized decision-making with retailers no participating in manufacturer's low-carbon promotion plan or participating in and centralized decision-making are established respectively in the dual-channel supply chain. It is also pointed out that the coordination of dual-channel supply chain can be achieved with retailers sharing manufacturers' carbon emission reduction cost and low carbon promotion cost. The results indicate that carbon reduction rate， low carbon promotion level and dual channel supply chain profit are positively related to influence coefficient of consumer' low carbon preference on demond， influence coefficient of retailers' brand elements on online and offline demand， and influence coefficient of low-carbon promotion on online and offline consumer demand. The carbon reduction rate is positively related to carbon emission trading price， and profit of dual-channel supply chain is inversely related to carbon emission trading price， while low carbon promotion level is an U-shaped relationship with carbon emission trading price. The carbon reduction rate， low carbon promotion level and dual channel supply chain profit are inversely related to cost coefficient of carbon emission reduction.
