中文摘要：

随着金融危机的蔓延，西方发达国家主导的贸易保护主义政策纷纷出台，传统贸易保护主义与新贸易保护主义政策交错，尤以后者更加隐蔽，企图以此刺激国内经济快速复苏。文章建立了基于开放经济奈件下的两国贸易模型，模拟分析了政策干预下自主性进口的改变影响均衡国民收入、外贸收支的原理，发现乘数越大的国家在贸易保护战中所受的损失也越大。文章指出，为快速有效的摆脱金融危机的影响，各国应该摒弃贸易保护主义政策，加强国际经济合作与协调。

英文摘要：

With the fINancial crisis spread quickly, western developed countries had implemented many trade protectionism policies attempting to stimulate the domestic economic recovery, among which are traditional and many undistinguishable new trade protectionism policies. In this paper, we build a two-country-trade model under the open economy. With data simulation, we analyzed how the national income and the balance of trade are influenced by the independent import which is intervened by the government. We discover that the bigger the multiplier the more loss the country will get form the war of trade protectionism. To get out of the financial crisis, every country should stop the trade protectionism policies to increase cooperation.
