中国高技术产业垂直专业化影响因素研究——基于各行业和各地区面板协整的实证检验

On Determinants of Vertical Specialization of High-tech Industry in China:An Empirical Analysis Based on Panel Cointegration Test from the Angle of Industry and Region

文章选取中国高技术产业1995-2008年行业和地区两个层面的面板数据,运用面板单位根检验、面板协整检验、面板FMOLS估计方法和面板DOLS估计方法对高技术产业垂直专业化的影响因素进行了经验分析。研究表明,外向度和资本密集度对高技术产业垂直专业化有着显著的正向影响,但对各行业和各地区垂直专业化的影响程度存在一定差异。为此,政府应采取相关政策措施,促进高技术产业垂直专业化趋势的不断深化。

This paper selects the panel data of high-tech industry from 1995 to 2008 in China from the angle of industry and region, and empirically analyzes the determinants of vertical specialization in high-tech industry by panel unit root test, panel cointegration test, panel FMOLS method and panel DOLS method. The re- sults show that foreign trade dependence and capital-intensive degree have signifi- cantly positive effects on vertical specialization of high-tech industry, but the effects vary with the industries and the regions. Therefore, governments should take some relevant measures to promote the deepening of vertical specialization in high- tech industry.
