摘　　要：Mazumdar(1996)的研究认为:当一国为资本品净进口国和消费品净出口国时,资本品的进口将导致资本品价格的下降进而引致折旧率的下降,结合Solow增长模型,折旧率的下降将促使一国投资率的上升并引致资本积累。本文运用中国数据对这一假说检验后认为:该理论只适用于小国贸易模式,对于诸如中国这样的贸易大国,比较优势决定下的贸易结构完全符合Mazumdar条件,但资本品进口和消费品出口并没有对中国资本积累起到促进作用,根本原因在于这样的贸易结构往往提高了资本品-消费品的相对甚至绝对价格,并最终恶化了中国的贸易条件,使得贸易收益并不明显。本文围绕这些这些问题进行了一定层次的论证。Mazumdar （1996） suggest that importing capital goods and exporting consumption goods will lead to a decline of the price of capital goods and the depreciation rate, which will contribute to a country＇s capital accumulation and thus lead to economic growth within Solow＇s growth model. This paper uses China data to test this hypothesis and conclude that Mazumdar＇s hypothesis applies only to a small country. For China, the trade Structure is in full compliance with the Mazumdar＇s conditions. However, trade Structure did not play a role in promoting China＇s capital accumulation. The fundamental reason is that such a trade Structure often worsens the terms of trade. On the other hand, whether the trade Structure could reduce the depreciation rate or not depends on the relative prices of capital-consumption goods rather than the absolute prices.
