本文首先对产业内贸易的研究方法进行了介绍,然后对中国装备制造业产业内贸易的水平和类型进行了实证研究,通过研究发现中国装备制造业贸易结构仍然呈以产业间贸易为主的格局,中国装备制造业产业内贸易类型细分呈现出以低质量产业内贸易为主、高质量产业内贸易次之、水平型产业内贸易比重最低的格局。 This article first introduces the research methods of intra-industry trade, and then conducts empirical research on the level and type of intra-industry trade in China’s equipment manufacturing industry. Through research, it is found that the trade structure of China’s equipment manufacturing industry still shows the pattern of inter-industry trade. The subdivision of intra-industry trade in China’s equipment manufacturing industry showed the pattern of low-quality intra-industry trade, followed by high-quality intra-industry trade, and the lowest proportion of horizontal intra-industry trade.
