Has Forestland Tenure Reform Enhanced the Carbon Sequestration Effect of Collective Forestland?Based on a Quasi-natural Experiment of the New Round of Forestland Tenure Reform
摘要
Abstract
Collective forestland,accounting for approximately 60％of China's forest resources,plays a crucial role in supporting carbon neutrality due to their significant carbon se-questration effects.The reform of forestland tenure has addressed issues such as unclear property rights and the absence of operational entities in collective forestlands.Evaluating the resulting car-bon sequestration effects is essential for understanding the potential of collective forest carbon sinks and supporting the goals of carbon neutrality.This study,based on the SCP theoretical model of forestland tenure reform,utilizes forest resource inventory data and the CCER methodology to estimate the carbon sequestration in collective forestlands for each province from 1992 to 2021.The recent round of reforms,particularly land tenure reform,serves as an exogenous shock i-dentification framework.The study employs the difference-in-differences method to assess the im-pact of forestland tenure reform on carbon sequestration in collective forestlands and validate its mechanisms.The findings are as follows:(1)Forestland tenure reform significantly increases carbon sequestration in collective forests,leading to an additional growth of approximately 3.5％in annual carbon sequestration.The carbon sequestration effects of forest property rights reform exhibit a lag,but over time,they show an increasing trend.(2)The new round of forestland tenure reform strengthens property rights stability and security,creating property rights incentive effects.This,in turn,enhances carbon sequestration in collective forests by increasing forestry cap-ital investment and expanding forest operational scale.(3)Heterogeneous analysis indicates that regions with better forest resource endowments and higher economic development levels experience a more pronounced promoting effect of forestland tenure reform on collective forest carbon seques-tration.To harness the carbon sequestration potential of collective forestlands,measures such as deepening complementary reforms to forestland tenure,promoting forestland carbon trading,and fa-cilitating forestland circulation are necessary.关键词
