Abstract:

【Objective】This study aims to investigate the production efficiency of carbon sequestration forestry and identify its key influencing factors. This exploration serves as a crucial foundation for the high-quality development of forestry in China. It not only provides essential insights for formulating differentiated forestry development policies but also facilitates the optimal allocation of forestry resources and promotes coordinated and balanced regional development across the country.【Method】The economic value and efficiency levels of carbon sequestration forestry in 31 provinces of China from 2003 to 2018 were evaluated using the volume expansion method, SBM model, Dagum Gini coefficient, and Tobit model. Building on this analysis, the study delved into the dynamic changes in comprehensive efficiency, pure technical efficiency, and scale efficiency, as well as their spatiotemporal differentiation. Additionally, the key influencing factors were systematically explored.【Result】The findings revealed that China’s forestry carbon sequestration storage level was relatively high, with Xizang, Sichuan, and Yunnan being the top three provincial area in terms of forestry carbon sequestration economic value. Comprehensive efficiency, pure technical efficiency, and scale efficiency exhibited significant regional disparities and demonstrated distinct spatial agglomeration characteristics. Both inter-regional and intra-regional differences were identified as the primary sources of regional variations in the production efficiency of carbon sequestration forestry in China. The proportion of forestry output value and investment in forestry human capital were found to positively influence the production efficiency of China’s carbon sequestration forestry, whereas per capita GDP and the incidence of forest diseases, pests, and rodents exerted a restraining effect.【Conclusion】China’s forestry development can achieve high-quality growth in carbon sequestration forestry by enhancing the efficient utilization of forestry resources, reducing regional efficiency disparities, and addressing key influencing factors. This approach will contribute to the sustainable and balanced advancement of the forestry sector.
