提出国际化供应链中上游R&D补贴模型,分析了国内最优R&D补贴对市场行为的影响.当国内消费者购买最终产品时,增加国外下游企业数量、改善上游企业技术效率、扩大国内对最终产品的消费比例,都会导致国内政府提高R&D补贴率和补贴总量.如果国内政府提高上游R&D补贴率,那么国内上游企业的R&D水平、行业产量、利润以及国外下游企业利润都会增加.
An upstream R&D subsidy model in an international supply chain was established. The effect of the optimal subsidy for domestic R&D on market behavior was analyzed. When domestic consumers purchased final products, R&D subsidy rate and total subsidy expenditure would increase with the number of foreign downstream firms, the technology efficiency of upstream firm and the percentage of domestic consumers. If domestic government improved R&D subsidy rate, domestic upstream firm's R&D level, industrial output, profit and downstream firms' profit would increase.
