Abstract: On the basis of game theory, an enterprise R&D model under conditions of R&D subsidy and pollution emission tax has been constructed. With the goal of emission reduction, optimal R&D level, optimal R&D subsidy, and optimal pollution emission tax for the enterprises are studied. The research results show that appropriate emission tax is of benefit to the improvement of the R&D investment and output of enterprises; the R&D subsidy is able to eliminate the effect of push aside and improve the R&D investment greatly. The environment pollution must be controlled in the scope of social acceptable; otherwise, the enterprise production activities will be ultimately stopped by the government.

Key words: emission reduction, spillover level, R&D subsidy, game
