Abstract: Considering both strategic consumers and government subsidies,the green supply chain models with subsidies(subsidizes manufacturer or consumers) and without subsidies and studies the manufacturer's decision on product green level and two-stage prices were established.The impact of both consumers' delay-purchase behavior and green preference on manufacturer's decision were discussed,and the impact of subsidy changing in two-stage on manufacturer's decision and profits through numerical simulation was explored.Study showed that both subsidies could increase product green level and manufacturer's profits,and product prices were higher when subsidizing consumers.In particular,when consumers' green preference k was lower than a threshold ke=0.966 9,the increase of subsidies in the first stage would increase products' green level,manufacturer's profit and product sales volume.When strategic level δ was lower than a threshold δe=0.685 9,the increase of first-stage subsidies would increase product green level and manufacturer's profits meanwhile increase second-stage subsidies would increase sales volume.

Key words: green supply chain, strategic consumers, government subsidy, two-stage pricing
