借助异质产品的Bertrand双寡头模型,在两国企业进行研发合作的条件下,本文分析了一国反倾销政策对该国企业和外国企业研发投入的影响。研究结论表明:与自由贸易相比,当产品的差异度较小时,受反倾销政策保护的本国企业会策略性地利用反倾销威慑而退出国外市场,这将使得外国企业垄断外国市场,提高外国企业研发投入的边际收益,进而诱使外国企业增加研发投入,而这也将提高本国企业研发投入的边际收益,不过由于本国企业退出外国市场会降低其研发投入的边际收益,因此本国企业研发投入的相对多少取决于这两种效应的相对大小。本文的研究对于重新认识反倾销的经济效应具有重要意义。
With the Bertrand duopoly model of heterogeneous products, this paper analyzes the impact of anti-dumping policies of a country on the R & D investment of domestic and foreign enterprises under the conditions of R & D cooperation between the two countries. The conclusion of the study shows that compared with free trade, when the degree of product differentiation is small, domestic enterprises protected by anti-dumping policy will use anti-dumping deterrence to withdraw from foreign markets strategically, which will make foreign enterprises monopolize foreign markets and improve the R & D of foreign enterprises However, since the exit of domestic enterprises from foreign markets will reduce their marginal revenue from R & D investment, the relative R & D investment of domestic enterprises will be relatively large How much depends on the relative size of the two effects. The research in this paper is of great significance to re-understand the economic effects of anti-dumping.
