创新因子对出口技术复杂度的影响--基于创新驱动发展战略的调节效应

Has the Innovation Factor Increased the Complexity of Export Technology--Based on the Moderating Effect of Innovation-Driven Development Strategy

本文基于2007—2019年中国省际面板数据,利用全局主成分分析法提炼出创新主体、创新投入和创新环境三类创新因子,并运用固定效应模型实证检验各类创新因子对出口技术复杂度的影响及创新驱动发展战略的调节效应。研究发现:创新主体、创新投入和创新环境均能显著提升出口技术复杂度;创新驱动发展战略仅在创新主体、创新投入与出口技术复杂度的关系间存在增强的调节效应。进一步异质性分析表明:在劳动密集型与资本密集型行业中,创新驱动发展战略正向调节创新投入与出口技术复杂度的关系;在技术密集型行业中,创新驱动发展战略正向调节创新主体与出口技术复杂度的关系。

Based on China's inter-provincial panel data from 2007 to 2019,this paper uses global principal component analysis to extract three types of innovation factors including innovation subject,innovation input and innovation environment,and uses a fixed effects model to empirically test the impact of various innovation factors on exports technology complexity and the moderating effect of innovation-driven development strategies.The study found that innovation subject,innovation input and innovation environment can significantly increase exports technology complexity.Innovation-driven development strategies only have an enhanced moderating effect on the relationship between innovation subject,innovation input and export technology complexity.Further analysis of heterogeneity shows that in labor-intensive and capital-intensive industries,innovation-driven development strategies positively regulate the relationship between innovation input and export technology complexity.While in technology-intensive industries,innovation-driven development strategies positively regulate the relationship between innovation subject and export technology complexity.
