Abstract: Under the background of low-carbon economy, according to current situation of Chinese manufacturing enterprises’ production and carbon emission, within the carbon emission constraints determined by the speed of economic growth, this paper constructs a carbon emission environmental policy model based on the ‘black box’ problem, and studies how the government to develop the combined composite control of carbon taxes and subsidies policy to control carbon emission of enterprises. Through the analysis of the design of government carbon regulation policy and its impacts on product prices, the demand of sales, comparing different carbon emission permit situations of different manufacturing enterprises carbon taxes, it comes to some conclusions: Unit carbon tax and excessive carbon emissions is not a certain linear relationship, but the general trend can be seen that the excessive amounts of carbon emission and unit carbon tax is a positive relationship. The government should adopt differential carbon taxes and subsidies to dynamically adjust them in view of the manufacturing enterprises different production quantities and carbon emissions. The regulation and control policy is based on the ‘black box’ problem change to product price range between -1% to 1.5%, which can reduce the carbon emissions while making product prices remain basically stable.
