中美高新技术产品贸易增长动因的实证分析

Empirical Analysis of Causes of Growing Trade of High-tech Products Between China and the United States

高新技术产品贸易在中美贸易中占有重要地位。在分析中美高新技术产品贸易发展现状的基础上,运用经常市场份额模型对中美高新技术产品贸易增长动因进行了实证分析,研究表明:竞争力提升是中国对美出口增长的主要基础,而进口增长则是竞争力提升和需求增长共同作用的结果;不同产品贸易增长的动因存在明显的差异。但是基于这种动因的增长却面临着诸多的不确定性,中国应该采取行之有效的策略以促进中美高新技术产品贸易的健康持续发展。

The trade of high-tech products is of importance to both China and the United States.Discussing the current situation of the trade,the model of normal market share was used to analyze empirically the causes of the growing Sino-America trade of high-tech products.The results revealed that the upgrading competitiveness was the main cause of the export growth from China to America,and the cause of import growth from America to China lay in the joint effect of upgrading competitiveness and growing demand.However,the growth rates of the trade of different products were obviously not the same due to different causes.Thus,such a growth was facing many uncertainties.China should take valid strategic measures to promote the trade of high-tech products between the two countries sustainably and soundly.
