Green innovation and SO₂ emissions: Dynamic threshold effect of human capital

Abstract

Green innovation is an effective path to decrease environmental pollutions. It is of immense interest to evaluate the roles of green innovation on SO 2 emissions reduction. We also investigate the static and dynamic threshold effect of human capital in the impacting paths of different innovations on SO 2 emissions. The empirical resultsshow that the design patent increases SO 2 emissions while the development of utility patent can decrease SO 2 emissions based on the static analysis and dynamic analysis.Both the "pollution halo" and the "pollution heaven" hypotheses of foreign direct investment (FDI) are validated in China. Moreover, green innovation positively affects SO 2 emission reduction based on the System Generalized Method of Moment (SYS-GMM) estimation. Both static and dynamic panel threshold regression results reveal that the positive effects of different innovations will become larger when human capital exceeds the corresponding threshold values. Hence, it is important to enhance green human capital.

What we learn from nexus between greener growth and energy‐related emissions: Sustainability perspective evidence in context of financial globalization

“…Eco‐innovation improves energy efficiency, enhances green energy technologies, promote sustainable transportation, sustainable land use and waste management. Previous studies also proved that eco‐innovation is essential for the reduction of GHG emissions (Razzaq et al, 2023; Luo et al, 2023; Ramzan, Abbasi, et al, 2023; Ji et al, 2020). Hence, we conclude that eco‐innovation is the source of reducing pollution effects by adopting energy‐efficient production techniques.…”

“…There is consensus among researchers on the positive influence of eco‐innovation on environmental performance. For instance, Razzaq et al (2023), Luo et al (2023), and Ramzan, Razi, et al (2023) argued that eco‐innovation is the source of reducing pollution effects by adopting energy‐efficient techniques of production. Eco‐innovation enhances energy efficiency by employing internal and external factors such as investment R&D activities, environmental regulations and energy material cost reductions (Chen et al, 2022).…”

Exploring the roles of natural resources on sustainability blueprint in G7 countries amidst green energy, technological innovation, and carbon‐tax intervention

“…Consequently, there is growing research interest in how technological innovation can mitigate unrelenting CO 2 emissions surges. For example, Luo et al (2023) evaluate how green innovation moderates environmental degradation measured (SO 2 emissions) by relying on the System Generalized Method of Moment (SYS‐GMM) within the intervening role of human capital. The empirical outcomes indicate components of green innovation such as design patents and development of utility patents escalate and reduce SO 2 emissions respectively.…”

The Green Solow model and the threshold effect of human capital on CO2 emissions

“…Thus, if 𝐴𝐴 𝐴𝐴 𝐵𝐵 is the same for all countries, it is normal to observe higher GDP growth rates for countries with a higher initial level of human capital. Regarding the relationship between human capital and emissions, Luo et al (2023) show that, above a certain threshold, human capital increases the beneficial effects of technological progress on sulfur dioxide emissions. In the same spirit, Yang et al (2017) find that high-quality human capital can be employed to lower fossil fuel consumption in manufacturing.…”
