Abstract: The regulation policies formulated by the government play key roles when manufacturers select production strategies. From the angle of low carbon, parameters such as government carbon tax coefficient, subsidy coefficient, production costs of low carbon products are introduced, under three models including mixed policies of tax and subsidy, single tax policy, and single subsidy policy. The evolutionary game model of decision making behavior of governments and manufacturers is established, conditions on which governments' policies and manufacturers' policies achieve a balance under different regulation policies are compared and analyzed. The factors affecting decision making of governments and manufacturers are studied.
The study result shows that when low carbon products produced by manufacturers are in the same proportion, if the government implements mixed strategy rather than single tax strategy or single subsidy policy, it will be more effective for increasing production proportion of manufacturers. The factors that influence government and manufacturer decision-making are closely related to government expenditure cost, tax coefficient, subsidy coefficient, manufacturer's product income and carbon emissions.
Finally, based on the perspective of government regulation, the measures to increase the proportion of manufacturers producing low-carbon products are given. The research conclusion can not only provide scientific theoretical basis to the formulation of government tax policies, but also give support to relevant management decision making of manufacturers.
