产业内贸易对我国制造业自主创新能力影响的实证研究

从产业内贸易的形成机理出发,利用1997—2010年我国29个制造业的相关数据,利用面板数据变截距模型分析了我国制造业整体的产业内贸易对其自主创新能力的影响,利用面板数据变系数模型分析了29个制造业行业的产业内贸易对其自主创新产出的间接影响效应和直接影响效应。实证结果表明:不同的制造业行业的产业内贸易对其自主创新能力的影响有所差异;在自主创新能力高的制造业行业中,产业内贸易对其自主创新的影响比较显著;在自主创新能力中等的制造业行业中,除了医药制造业、黑色金属冶炼及压延加工业的产业内贸易对其自主创新能力有显著影响外,其他制造业行业的该影响均不显著。

Empirical Research on Impact of Intra-industry Trade on Independent Innovation Capability of Manufacturing Industry in China

From five formation mechanisms of intra-industry trade,this paper uses the data about 29 manufacturing industries in China during 1997-2010,and analyzes the impact of intra-industry trade of whole manufacturing industry on the output of independent innovation through constructing a panel data model with variable intercept,and analyzes indirect and direct effects of intra-industry trade of 29 manufacturing industries on the output of independent innovation through constructing a panel data model with variable coefficient.The empirical results show as follows:the impacts of intra-industry trade of different manufacturing industries on their independent innovation capabilities are different;in those manufacturing industries with high independent innovation capability,intra-industry trade has significant impacts on the output of independent innovation;in those manufacturing industries with medium independent innovation capability,except pharmaceutical manufacturing as well as ferrous metal smelting and rolling processing industry,the intra-industry trade of other manufacturing industries don’t have significant impacts.
