Abstract:

In the strategic background of high-quality innovation and development in China’s manufacturing industry, a panel threshold model of the influencing mechanism of external knowledge sourcing on high-quality innovation in the manufacturing industry is constructed from the perspective of innovative human capital, and the nonlinear influence of external knowledge sourcing driving high-quality innovation under the heterogeneous effect of innovative human capital in different industries is explored. The results show that the influence of external knowledge sourcing on high-quality innovation in the manufacturing industry is influenced by the heterogeneous threshold effect of innovative human capital level. The low level of innovative human capital significantly promotes the effect of high-quality innovation based on external knowledge sources. With the improvement of innovative human capital level and the breakthrough of the “critical value”, the effect of high-quality innovation based on external knowledge sources is inhibited to some extent, and the relationship between external knowledge sources and high-quality innovation is in an inverted U-shape. In addition, the innovative human capital of most manufacturing industries in China is at a medium level, and external knowledge source is a significant driving force to promote high-quality innovation. However, it is necessary to be aware of the negative threshold effect of innovative human capital in order to maintain the vitality of high-quality innovation.

Key words:

external knowledge source, high quality innovation, innovative human capital, heterogeneous threshold effect

摘要：

在中国制造业高质量创新发展的战略背景下，从创新型人力资本视角构建外部知识源化对制造业高质量创新影响机理的面板门槛模型，探讨在不同行业创新型人力资本异质效应下外部知识源化驱动高质量创新的非线性影响。研究发现：外部知识源化对制造业高质量创新的影响受到创新型人力资本水平的异质门槛效应。较低的创新型人力资本水平显著推动了外部知识源化的高质量创新的作用，随着创新型人力资本水平的提升并突破“临界值”，在一定程度上抑制了外部知识源化的高质量创新效应，即外部知识源化与高质量创新呈倒U型关系。此外，在行业上，中国大多数制造业行业的创新型人力资本处于中等水平，外部知识源化是推动高质量创新的显著动力，但需要警惕创新型人力资本带来的负向门槛效应，以此来保持高质量创新活力。
