Evaluating the link between innovative human capital and regional sustainable development: Empirical evidence from China.

Innovative human capital (IHC) can boost the economic growth of nations. However, in recent years, economies have become more attuned to sustainable development. In this context, it is important to assess the potential impact of IHC on green growth. Against this background, this study empirically examines the role of IHC on regional green growth in China, considering the spatial spillover effect and focusing on the quantity and quality of human capital and its direct and indirect effects on green growth. To this end, this paper adopts the spatial Durbin model, constructs an indicator system to evaluate green growth, and establishes a calculation formula for the quantity and quality of IHC. The empirical analysis provided some important findings. First, IHC and green growth have strong spatial correlation characteristics. Second, the quantity of IHC has a significant positive impact on regional green growth; however, the quality of IHC does not promote regional green growth. Third, the quantity and quality of IHC indirectly improve the level of regional green growth through technological progress. Finally, the role of IHC and its spatial spillover effect in improving the regional green growth level are most obvious in the central and western regions of China. Therefore, promoting green growth requires enhancing the accumulation of IHC and narrowing the gap between eastern and western China in the accumulation of IHC.
