Our country can apply strategic trade policy to coal industry. This article has proven in our country the feasibility in tradition industry—the coal industry apply the strategic trade policy, simultaneously according to such assumption, uses the model of Dixit, with 2003 data in Chinese coal industry, examine the effect of tax rebate for export, Empirical study has proven showed that, tax rebate for export promote coal volume of exports, indeed shift the profit to our manufacturer and enhanced the national welfare.
