国际技术扩散是提高一国技术创新能力的重要途径。然而，当前国际贸易保护主义重新抬头，企业通过国际贸易获得技术扩散的效应日益减弱。此时，一国如何制定应对策略以提升本国的技术水平并获得经济和社会的长久发展，是各国特别是发展中国家面临的紧迫问题。文章利用纳什均衡、变分不等式和Lagrange对偶理论建立多期国际供应链网络均衡模型，分析提高关税和限制技术扩散对技术进步、供应链成员利益和社会整体的经济和环境效益的影响。结果表明:两国企业成本对称且两国采取限制技术扩散对等措施之下，加大关税增长的幅度将扩大本土产品的生产和消费，消费者剩余增加，但企业利润和社会福利减少，产品技术水平降低。适当的技术补贴对消费者、企业和整个社会都有益，有利于技术水平的提高。限制技术扩散对消费者、企业和社会整体都不利，也不利于技术水平的提高。由此得出，经济实力和科技水平相当的国家或地区应加强自由贸易区的建设，以实现自由贸易和技术合作带来的互利共赢。
Multi-period International Supply Chain Network Equilibrium under Technology Diffusion and Trade Protectionism
International technology diffusion is an important way to improve a country's technological innovation capability.However,under the current situation of the resurgence of international trade protectionism,the effect of technology diffusion obtained by enterprises through international trade is weakening.Under this new international situation,how to formulate coping strategies to improve its technological level and achieve long-term economic and social development is an urgent problem faced by all countries,especially developing countries.In view of this,Nash equilibrium,variational inequality and Lagrange dual theory are used to establish a multi-stage international supply chain network equilibrium model to analyze the impact of raising tariffs and limiting technology diffusion on technological progress,the interests of supply chain members and the economic and environmental benefits of the whole society.In the model,different values of the tax factor Ktmn are set to distinguish the VAT on domestic sales from the tariff on foreign sales.It should be noted that the taxes in this article are ad valorem taxes.By setting different technology diffusion influence factors etim,the government can control technology diffusion differently.In addition,the government subsidizes the technology investment of manufacturers,and the amount of subsidy is a certain proportion of the technology investment.Combined with numerical examples and network equilibrium variational inequality conditions,the projection contraction algorithm is used to design the program and run it through Matlab software.The following conclu-sions are drawn from the analysis of numerical results:Under the condition that the costs of enterprises in the two countries are symmetrical and the two countries take equal measures to limit the technology diffusion,increasing the rate of tariff growth will expand the production and consumption of local products,increase the consumer surplus,but reduce corporate profits and social welfare and the technical level of products.Appropri-ate technical subsidies are beneficial to consumers,enterprises and the whole society,and are conducive to the improvement of technical level.Restricting technology diffusion is not good for consumers,enterprises and society as a whole,nor is it conducive to the development of technology level.Therefore,countries or regions with similar economic strength and scientific and technological level should strive to build free trade zones to achieve mutual benefit and win-win results brought about by free trade and technical cooperation.
