中国高技术产品产业内贸易影响因素研究

Research on the determinants of China's high-tech intra-industry trade

根据联合国贸易数据库统计数据,分析了中国高技术产品的贸易现状,采用GL指数、边际产业内贸易指数,从不同角度测度和分析了中国高技术产品的产业内贸易水平,运用面板数据对国家层面的影响因素进行了研究。结果发现,中国高技术产品产业内贸易大而不强,产业内贸易结构不均衡,急需大力发展航空航天等产业。中国与贸易伙伴的人均收入差距、技术差距和外商直接投资都是影响产业内贸易发展的因素,其中人均收入差距和产业内贸易具有显著的负相关性,其余因素根据贸易伙伴的不同而有所差异,并根据研究结果提出了相关建议。

According to UN trade statistics, this paper analyzes the trade situation of high - tech products. Then it uses China＇ s high - tech GL index, and marginal intra - industry trade index to measure the level of high - tech intra - industry trade. Final- ly, by use of panel data, it makes an empirical study of the national determinants of the high - tech intra - industry trade. The .9 ndings indicate that China＇ s high - tech intra - industry has a high level but it is not strong and the structure is imbalaneed, so it is quite urgent to develop the high value - added industry, like Aerospace. The GDP per capita gap, technical differences and foreign direct investment are the determinants of intra - industry. The GDP per capita gap variance is significantly negative corre- lated with the intra - industry trade ; the effect of other factors is different based on the trading partners. Upon those conclusions, the paper provides some policy recommendations.
