Abstract：Considering the difference of dual-channel product prices and consumers' low carbon preference under carbon tax policy， using the game model of carbon reduction technology innovation investment on dual-channel supply chain， the decisions of a retailer's order quantity and a manufacturer's carbon reduction innovation investment are studied. The results show that the dual-channel supply chain can be coordinated with two part tariff contract and transfer payment compensation contract. The total sale quantity of dual-channel and carbon reduction rate will be higher under the case of cost-sharing of carbon reduction technology innovation investment compared to the case of individual carbon reduction technology innovation investment， and the dual-channel supply chain profit depends on the proportion of retailer's cost-sharing on the carbon reduction technology innovation investment. The total sale quantity of dual-channel， carbon reduction rate， manufacturer's profit and supply chain profit will increase positively with the carbon tax， while the retailer's profit will reduce. The carbon reduction rate and total sale quantity of dual-channel will reduce negatively with the channel competition strength， but manufacturer's profit， retailer's profit and dual-channel supply chain profit will decrease first and then increase. The total sale quantity of dual-channel， carbon reduction rate， manufacturer's profit and supply chain profit will increase positively with the consumers' low carbon preference， but the retailer's profit will decrease first and then increase.
