Study on Optimization of Anti-dumping Duty Rate Based on Linear Programming Model of Input-output Method

According to the tariff theory, taking and imposing trade protective measures to a kind of imported intermediate goods, such as the antidumping duty etc., will not only affect the price of products subject to anti-dumping, but also influence the price of its upstream and downstream products. That is ripple effect caused by trade protective measures. Introduces the effect of anti-dumping duty in the international trade protection, summarizes the determination method of anti-dumping tax rate in domestic and international theory and practice, and analyzes the deficiencies of these methods. Establishes the valuable input-output table of antidumping products, and put forward a linear programming optimized model of gross domestic product and gross tariff income, which reflects the ripple effect of anti-dumping duty. This model provides the applicable approaches for inferring anti-dumping duty rate.
