摘　　要：长期以来,贸易对技术进步和经济增长的效应得到了经济学家的广泛关注。但现有理论对它的解释力十分微弱,许多实证研究的结论也不尽相同且存在广泛争议。本研究以新增长理论为基础,将知识贸易从贸易活动中抽象出来,引入知识贸易方程,构建数学模型,并采用比较静态分析方法分析不同贸易政策对模型结果的影响。这既填补了新增长理论未对贸易进行建模的空白,也在一定程度上增强了理论对上述效应的解释力。研究结果表明:贸易是技术进步和经济增长的原因;但它并不能使技术进口国实现对技术出口国的反超战略;另外,贸易保护政策阻碍技术进步,并降低经济福利。For a long time, the effects of trade on technological progress and economic growth have been aroused wide concern of the economist. To explain it, the power of the existing theory, however, is very weak, and the conclusions of many empirical studies are different and controversial. In this study, based on the new growth theory, knowledge will be abstracted from the trade activities, and a knowledge trade equation will be introduced to build a mathematical model. Then, the comparative static analysis methods will be used to analyze the influence of different trade policies on the model results. This fills the blank of the new growth theory, which has not modeled trade, and, to a certain extent, enhances the explanatory power of the theory on the above effects. Conclusions show that trade is the cause of the technological progress and economic growth but couldn＇t make the catching-up strategy of technology importer come true. In addition, the trade protection policies will block technology advance and reduce the economic welfare.
