This paper explores how the increase in income taxes in relation to foreign-funded enterprises affects the social welfare of China. The theoretical analysis indicates that increasing the income taxes levied on the foreign-funded firm tends to be beneficial to the social welfare of China. However, this tax policy may be detrimental to the social welfare of China only if the marginal cost of the domestic firm is higher than that of the foreign-funded firm, and this cost differential effect outweighs both the direct and strategic effects.
