摘要: 异质产品条件下,通过比较国内外厂商生产两种不同质量的产品进入本土企业对所在市场产生的影响,发现最大收入关税并不总是大于最佳福利关税,最大收入关税和最佳福利关税的相对大小主要取决于两种产品间质量的相差大小.在Cournot竞争条件下,如果两种产品的质量相差s<23,那么最大收入关税大于最佳福利关税;如果不是这样,则最大收入关税小于最佳福利关税.此外,异质产品条件下,最佳关税对本土企业的影响还跟两种产品的可替代程度有关.

Abstract: Under the condition of heterogeneous products and on the basis of a comparison of the impact of the introduction of the domestic and foreign products of different qualities into local enterprises on their markets, it is found that the maximum income tariff is not always greater than the best welfare tariff. The relative size of the maximum income tariff and the welfare tariff depends largely on the difference in the quality of the two products. In the Cournot competitive conditions, if the quality difference of the two products is less than 2/3, then the maximum income tariff is greater than the best welfare tariff; if not, then the maximum income tariff is less than the best welfare tariff. In addition, under the condition of heterogeneous products, the the impact of the best tariff on local enterprises can be related to the substitution degree of the two products.

Key words: heterogeneous products, maximum income tariff, best welfare tariff
