Abstract: In recent years, the adverse impact of the carbon dioxide emissions on the climate and environment is increasing, the constraints and norms of the production and management behavior of enterprise done by government is also gradually enhanced, carbon cap and trade policy has become an important measure for the government to control and manage the carbon emissions of the enterprise, and it will has a direct impact to enterprise on production and pricing strategy.At the same time with the increasing of the public's environmental protection and health awareness, the demand for green and low carbon products will be more and more bigger for public.Green and low carbon products will be the inevitable direction of enterprise production.Under the new environment of green technology investment and low carbon production, the enterprise product pricing inevitably faces a new problem.Under the condition of carbon cap and trade and with the considering of green technology investment, the enterprise product pricing strategy has become the enterprise problems needed to resolve.Therefore, the research on carbon cap and trade policy under the enterprise production and pricing strategy has very important practical significance.Whereas in the past the study literature about the enterprise product pricing strategy from the angle of considering green technology was arely seen, and it will become the main source for us to study the problem in this paper.From the perspective of microcosmic low-carbon economy, the pricing strategy model is mainly constructed under carbon cap and trade policies, carbon quota policy, carbon cap and trade policy, and in the carbon cap and trade policy with the green technology input respectively, and then some researches on the pricing strategy for the enterprise on the three kinds of cases are given, in order to private some beneficial reference to enterprises under the condition of different corresponding pricing strategy.Under the carbon cap and trade regulation with the consideration of green technology investment, enterprise pricing strategy model is constructed, and the optimization theory and methods are used to analyze the model.Combined with the numerical analysis method the correctness of the model has been verified, and then the related conclusion is obtained.As the basis of comparative analysis, first of all, pricing strategy of the enterprise is researched in case of no carbon limit.Basis on this, according to the progressive thinking that consider the limitation of carbon, carbon quotas and trading, carbon cap and trade under the consideration of green technology input, the pricing strategy of corresponding enterprise is analyzed, and then gets the corresponding pricing strategy of the enterprise under different cases is gotten.The results show that: (1) The manufacturer's profit and price with carbon emission constraint will be lower than the case without carbon emission constraint.(2) The manufacture's maximum price under cap-and trade is lower than the case without carbon emission constraint, and higher than the case under cap.The manufacture's maximum price under cap-and-trade depends on the marginal profit in cap and The maximum expected profit in this situation depends on the initial allowance.(3)The manufacture's maximum price concerning green technology under cap-and-trade is lower than the case without carbon emission constraint.The manufacture's maximum price concerning green technology under cap-and-trade depends on the marginal profit in cap.(4)Under cap-and-trade, proper green technology input will improve manufacture's expected profit.In the part of the numerical simulation analysis, according to the enterprise product pricing strategy under the carbon cap and trade policy with considering green technology input, a numerical example is designed, and the pricing strategy of the enterprise under the stochastic market demand distribution function is analyzed, and further the correctness of the model is verified.The research of this paper provides a basic idea and framework to the related research of enterprise product pricing strategy that consider green technology input under carbon cap and trade policy, and it provides a reference for the government to consider from the angle of environment and the enterprise at the same time and formulate the carbon cap and trade policy which is good for not only the environment but also the enterprise.
