中国工业自主创新能力提升的内在机理分析——基于产业外部性的视角

Analysis of the Transmission Mechanism of Upgrading China's Industrial Innovation Capacity from the Perspective of Industrial Externalities

基于产业外部性的视角,研究我国工业技术创新通过技术溢出实现自主创新能力提升的内在机理并加以实证检验。研究结论为:产业间贸易的前向关联对普通创新有明显促进作用,但对创新程度较高的发明作用不明显;产业间贸易的后向关联由于受到产权结构和"被迫引进"现象的负面影响,对自主创新表现出抑制作用;产业集聚对于创新程度较高的发明有明显促进作用,对普通创新作用不显著;进一步考察发现,产业集聚能加强前向关联的技术溢出,并能减轻甚至消除后向关联对创新的抑制作用。

Based on the perspective of industrial externalities, this paper firstly analyzes the inherent mechanism for how China＇s industrial technology innovation influences its independent innovation capability through technology spillovers. Then, it empirically tests the transmission mechanism and concludes that： the forward linkage of industrial trade significantly stimulates indigenous firms＇ low-degree independent innova- tion while its contribution is less obvious in the development of high-degree independent innovation; on the other hand, because of the negative effect of property right structure and the substitute effect of technology import, the backward linkage of industry trade impedes the innovation. Moreover, industrial agglomeration significantly stimulates indigenous firms＇ high-degree independent innovation while its contribution is less ob- vious in the development of low-degree independent innovation. It further finds that industrial agglomeration can enhance the technology spillover of the forward linkage of industrial trade and relieve or eliminate the in- hibitory action of the backward linkage of industrial trade.
