As the development of economy, industrialization has brought development and convenience for human beings, but it also brings greenhouse gases which have caused serious impact on the climate and environment. The global warming, extreme climate and haze which has attracted more and more attention make the government, enterprises and people pay more attention to the construction of low carbon society. In the process of realizing low carbon society, the realization of low carbon target mainly depends on the participation of enterprises in the supply chain, as the enterprises are the main source of carbon emissions.Based on the situation, this paper has built a two-stage supply chain system with a manufacturer, a retailer and a single period product, from the angle of supply chain. The problem of how to make decisions and build low carbon supply chain under carbon taxes and subsidies is studied, through the method of game theory, supply chain coordination and other methods. And many meaningful conclusions are gained.Firstly, this paper has built supply chain model without carbon taxes, and finds that the parameter of carbon emission of per product is more suitable for reflecting enterprise’s production technology and operation ability than total carbon emission by analyzing of the problem of carbon emissions. The measurement method of carbon tax, characteristics and applicable conditions of different carbon taxes are studied.Secondly, two forms of low carbon supply chain decision making models, low carbon technology investment and recycling low carbon supply chain, are built. In the model flow-carbon technology investment low carbon supply chain, consumer’s low carbon preference is considered, and the optimal decisions are studied. Then a two-stage supply chain decision making model under stackelberg game and retailer’s subsidy for the manufacture is built. By theoretical analysis and numerical simulation, it is found that subsidies can encourage carbon reduction, fixed cost has negative impact on enterprises’enthusiasm to carbon reduction, and low-carbon preference has positive impact on carbon reduction under low carbon technology investment subsidy. Subsidies are affected by the methods of profits distribution. Low carbon supply chain decision making under subsidies can improve carbon emissions per product and the enterprises’profits, and both the two kinds of subsidy can realize the coordination of supply chain decisions.Finally, with the combination of carbon taxes and subsidies, the enterprises’ stackelberg equilibriums are gained in the two kinds of low-carbon supply chain. It is found that subsidies are affected by methods of profit distribution and carbon taxes, and carbon taxes have positive effect. Carbon taxes have positive effect on carbon emission amount and carbon emission amount per product of low-carbon supply chain under the combination of carbon taxes and subsidies is highest. Carbon taxes have negative impact on profit of the manufacture, and have first positive and then negative impact on profit of the retailer under low-carbon technology, and have positive impact on profit of the retailer under recycling.
