【摘要】HOV模型指出产品间的贸易本质上也是要素间的贸易,一国进行自由贸易时,将成为其丰裕要素的净出口国,稀缺要素的净进口国。本文应用贸易要素含量研究方法,对1992-2013年中国主要农产品贸易的要素含量进行核算,将土地、劳动力、资本要素整合进一个统一的分析框架,并基于Leamer改进,对相对要素禀赋进行考察。核算结果表明:我国劳动力要素的净出口程度趋于下降;土地要素的贸易含量呈现净进口态势;资本要素的净进口不断扩大。此外,劳动力要素相对具有比较优势,土地、资本要素则不具有比较优势,农产品贸易对不同生产要素的影响不同。

【Abstract】The HOV model shows that trade among products is essentially a trade among factors. When a country participates in free trade, it becomes a net exporter of factors of which it has an abundance and a net importer of factors that are rare in the country. This article uses the factor content of trade approach to calculate the factor content, including land, labor, and capital of major Chinese agricultural products between 1992 and 2013 and organize these three factors into a single analytical framework. The article also studies China’s relative factor endowments based on Leamer improvement. The calculations indicate that the net total labor factor export is decreasing. The trade content of land factor is a net import, and the capital factor which is a net import is increasing. Meanwhile, the data shows that China has a comparative advantage in agricultural labor, but not in land or capital. Trade of agricultural products in different qualities have different influences on the production factors.

    [1]. ①The theory expansion based on the HOV Model by Leamer is called “Leamer improvement.” Leamer suggests that the proper method to deduce the relative abundance of factors is to utilize factor content (including factor content of trade and direct factor mobility) under the condition of unbalanced trade. Now that the mobility of agricultural production factors is insufficient, this method is applicable to this article as well. The Leamer improvement is applied to the latter section of this article, which aims to measure the relative abundance and comparative advantage of China’s agricultural factors. [^Back]

    [2]. ②The Major agricultural products include labor-intensive and land-intensive agricultural products. [^Back]

    [3]. ③The factor content of agricultural trade in this article refers to the trade volume of all factors contained in agricultural trade, and the reference (Liu, 2011) adopts the saying of trade content of one factor to represent the trade volume of one factor, and the trade content is comprised of the net import and net export of factors.
