Abstract Based on the government subsidy policies, this paper establishes three Stackelberg game models by considering consumer’s green preferences in green supply chain. The subsidy effects of those policies under the condition of same government expenditure are compared and analyzed through theoretical proof and numerical simulation. The results show that the changes of green preference coefficient and input cost coefficient have no impact on the rankings of the three kinds of subsidy policies; if the green degree of product, the manufacturer’s profit and the retailer’s profit are used as the evaluation standards for those policies, then the corresponding optimal subsidy policies are the policies based on the input costs, the production cost and the green degree, respectively. The changes of government subsidy coefficients have no impact on the rankings of the green degree of product and the manufacturer’s profit under the three kinds of subsidy policies, but have impact on the ranking of the retailer’s profits.
