The Introduction Of Technology Export Comparative Advantage Of China's High-tech Products

We spent billions of foreign currency to import advanced technology every year. Did these expensive imported technologies improve high-tech industry development and technology improvement? How much do these imported technologies improve comparative advantage of high-tech industry export, which the paper try to study the relations and the effect?Comparative advantage theory of high-tech products export is based on comparative advantage theory. Comparative advantage theory is based on nature resource element, capital element, labor element, technology element, information element, organization element and system element. Imported technology can effect on technology element, labor element, system element and others, which effect comparative advantages of high-tech industry export.In order to analyze the comparative advantages of high-tech products export, data of high-tech products import and export from 1985 to 2006 are used. The result shows that trade competitive index was negative before 2004, which means less competitive. But trade competitive index is progressing, which shows the competitiveness and the comparative advantages of high-tech industry export are improving.Based on technology importation and comparative advantages theory, distributed-lag model and cointegration model are used to analyze the relation and the effect between technology importation and comparative advantages of high-tech industry export, which made the following conclusion.Distributed-Lag Model analysed and showed that one unit (billion US dollor) technology importation can improve 0.201 the comparative advantages of high-tech industry export at the first year and 0.14 at the second year. Technology importation can improve comparative advantages of high-tech industry export and high-tech industry development. Cointegration model proved Technology importation and the comparative advantages of high-tech industry export have long term Cointegration relation.If the unit is 100 million Usdollar, Distributed-Lag Model analysed and showed that one unit technology importation can improve 0.00201 the comparative advantages of high-tech industry export at the first year and 0.0014 at the second year, which is very less effective. Technology importation is not so effective for the comparative advantages of high-tech industry export.There are so many reasons for these. The suggestions are made to improve the effect between technology importation and comparative advantages of high-tech industry export.
