【摘要】：在国内产能过剩、产业升级的背景下,政府提出了中国版“马歇尔计划”,大力发展“一带一路”建设,高技术出口型企业和产业“走出去”成了国家未来发展的重中之重,高技术产业迎来历史发展机遇期。近十年来,我国对外贸易取得了举世瞩目的成绩,尤其是高技术产品贸易额增速惊人。然而,现阶段我国高技术行业进出口贸易主要以加工贸易为主,且技术含量低,严重阻碍了我国高新技术产业的发展。所以在未来高技术产业的发展中,我们不能只注重贸易数量,更要注重贸易质量。本文首先分析了中间产品进口对高技术产品出口技术含量的影响机制,一是具体从技术溢出、规模经济以及贸易竞争角度进行效应机制分析,二是从全球化生产、垂直专业化以及投资贸易一体化角度来进行路径机制分析。接着分析我国中间产品进口与高技术产品出口技术含量的现状,具体分析了中间产品进口的规模与结构,同时采用Hausmann(2007)模型测算了中国高技术产业出口技术含量,分析我国高技术产业出口技术含量的变动,并对其进行横向和纵向的比较。得出虽然我国高技术产品出口额多,但是技术含量比较低,与发达国家比还有一定距离。之后利用2000—2013年我国高技术五大行业面板数据进行实证分析,首先选取中间产品进口、全球化生产指数和垂直专业化指数等变量,利用静态面板模型和动态GMM模型对高技术出口技术含量进行总体性分析,然后再引入虚拟变量,分析高技术五大行业中间产品进口对其出口技术含量的影响。实证结果认为总体的中间产品进口对高新技术产品出口技术含量具有显著地正向影响,同时,生产全球化、垂直专业化以及投资贸易一体化均对高新技术产品出口技术含量有正向影响,且垂直专业化对其影响程度最大。FDI、RD和中间产品进口均有助于提升产品的出口技术含量。但对细分行业的中间产品进口与出口技术含量的关系是不确定的,医药制造业等三类产品的中间产品进口会促进高技术产品出口技术含量的提升,而其余两大类中间产品进口则会阻碍其出口技术含量的提升。最后,在实证结果的基础上,提出了相关政策建议。
[Abstract]:Against the background of overcapacity in China and industrial upgrading, the government has put forward a Chinese version of the Marshall Plan, vigorously developed the construction of "Belt and Road", and high-tech export-oriented enterprises and industries have become the top priority of the country's future development.The high-tech industry ushered in the historical development opportunity period.In the past ten years, China's foreign trade has made remarkable achievements, especially the rapid growth of the volume of high-tech products.However, at the present stage, the import and export trade of high-tech industry in China is mainly focused on processing trade, and the technology content is low, which seriously hinders the development of high and new technology industry in our country.Therefore, in the future development of high-tech industries, we should not only focus on the quantity of trade, but also on the quality of trade.This paper first analyzes the influence mechanism of intermediate product import on the technology content of high-tech product export, one is from the perspective of technology spillover, scale economy and trade competition, the other is from the perspective of global production.Vertical specialization and investment and trade integration to analyze the path mechanism.Then it analyzes the current situation of China's intermediate product import and high-tech product export technology content, analyzes the scale and structure of intermediate product import, and calculates the export technology content of China's high-tech industry by using Hausmann's 2007) model.The change of export technology content of high-tech industry in China is analyzed and compared horizontally and vertically.It is concluded that although the export value of high-tech products in our country is much, the technical content is relatively low, and there is still a certain distance compared with developed countries.Then we use the panel data of five high-tech industries from 2000 to 2013 to carry out empirical analysis. First of all, we select variables such as import of intermediate products, global production index and vertical specialization index, etc.The static panel model and dynamic GMM model are used to analyze the total content of high-tech export technology. Then virtual variables are introduced to analyze the influence of import of intermediate products in five high-tech industries on its export technology content.The empirical results show that the overall import of intermediate products has a significant positive impact on the export technology content of high-tech products, and at the same time, the globalization of production.Vertical specialization and integration of investment and trade have positive effects on the export technology content of high and new technology products, and vertical specialization has the greatest influence on it.However, the relationship between the import of intermediate products and the technical content of exports is uncertain. The import of intermediate products of three kinds of products, such as the pharmaceutical manufacturing industry, will promote the upgrading of the export technology content of high-tech products.Imports of the remaining two major categories of intermediate products will hinder the upgrading of their export technology.Finally, on the basis of empirical results, the relevant policy recommendations are put forward.
