数字经济对林业绿色全要素生产率的影响研究OA

Enhancing forestry green total factor productivity(FGTFP)is crucial for promoting high-quality green development of foresty industry.Based on provincial panel data from 2012 to 2022,this paper systematically investigates the impact of the digital economy on FGTFP through fixed-effect models,mediating effect analysis and robustness testing.Key findings and conclusions include:(1)The digital economy significantly enhances FGTFP,with a promotion coefficient of 0.890 and a system GMM coefficient of 0.752 after endogeneity control.This conclusion remains valid after rigorous robustness and endogeneity tests.(2)Mechanism analysis reveals that the digital economy indirectly promotes FGTFP through two pathways:optimizing the forestry industrial structure and driving green technological innovation.The mediating effect of industrial structure optimization accounts for approximately 18.6%,while that of green technological innovation contributes about 27.3%,forming a comprehensive transmission pathway from digital empowerment to green development.(3)The digital economy exerts more pronounced effects on eastern regions,areas with scarce forest resources,and regions with stringent environmental regulations,whereas its driving force is relatively weaker in central and western regions,areas rich in forest resources and regions with lenient environmental oversight.This paper examines the long-term steady-state impact of the digital economy on FGTFP from a dynamic panel perspective,identifying dual mediating mechanisms of"industrial structure optimization"and"green technological innovation".Through three heterogeneous grouping approaches,it clarifies the differentiated operational boundaries of the digital economy.Policy recommendations:strengthening forestry digital infrastructure,deepening the integration of digital technologies across the entire industrial chain,and enhancing the dual-driven approach of industrial structure optimization and green technological innovation,implementing region-specific adaptation strategies to promote synergistic governance between environmental regulations and the digital economy,thereby creating combined effects of constraint and empowerment.
