Abstract

Abstract:

Objective: To clarify the significance of digital new quality productivity in advancing the construction of a modern industrial system with Chinese characteristics, to elucidate the mechanisms by which digital new quality productivity promotes the high-quality development of the forestry industry in mountainous areas, to enrich and advance the theoretical and policy research connotations of forestry new productivity. This provides support for improving the policy framework for high-quality development of the forestry industry. Method: Based on panel data from 26 counties in the mountainous areas of Zhejiang Province from 2011 to 2022, this study employs mediation effect models and panel threshold effect models to explore the impact and mechanisms of digital new quality productivity development on the high-quality development of the forestry industry. Result: 1) The baseline regression analysis shows that digital new quality productivity significantly enhances the high-quality development level of the forestry industry in mountainous areas. 2) The mechanism analysis shows that digital new quality productivity promotes the high-quality development level of the forestry industry through pathways such as production factor optimization, forestry human capital accumulation, and technological innovation. 3) The heterogeneity analysis shows that among the three dimensions of digital new quality productivity, only digital labors and digital labor objects significantly enhance the high-quality development lever of forestry industry, while digital labor materials have no significant effect; the development level of digital new quality productivity significantly improves the optimization of forestry industry structure and upgrading of forestry industry structure; digital new quality productivity enhances the high-quality development of forestry industry in both spanning development counties and ecological development counties, with better effects observed in spanning development counties. 4) The threshold effect analysis shows that the positive effect of digital new quality productivity on the high-quality development of forestry industry is only activated when government support levels surpass the threshold value; as informatization levels exceed the threshold, the positive impact of digital new quality productivity on forestry industry high-quality development gradually weakens. Conclusion: The digital new quality productivity significantly enhances the high-quality development of forestry industry in the 26 mountainous counties of Zhejiang Province. Production factor optimization, forestry human capital accumulation, and technological innovation play significant mediating roles. To fully leverage the role of digital new quality productivity in promoting high-quality development of the forestry industry, it is essential to prioritize investments in digital infrastructure and specialized talent, implement differentiated policies based on regional variations, enhance the efficiency of digital resource utilization in ecological development counties, and ensure that informatization aligns with industrial needs. Efforts should focus on improving government support levels to further unlock the potential of digital new quality productivity, driving forestry industry structure optimization and upgrading, and fostering exemplary models of digital new quality productivity empowering high-quality development of forestry industry.

Key words: new quality productivity, technological innovation, forestry industry, high-quality development, production factor optimization
