营林固定资产投资作为林业经营和风险管理的重要经济手段,对于林业发展与森林质量提升有重要影响。森林吸收大气中CO_2气体以碳化合物储存起来,形成碳汇过程。研究运用计量统计分析方法建立滞后模型,分析林业营林固定资产投资与林业碳储存增量的协整关系以及2个变量之间的Granger因果关系,得出我国林业营林固定资产投资对于林业碳储存增量存在长期的协整关系,但是其影响相对较小,且存在一定滞后期,投资效率偏低。
Investment in fixed assets of forest management As an important economic measure for forestry management and risk management, it has a significant impact on the development of forestry and the improvement of forest quality. The forest absorbs CO 2 in the atmosphere and stores it as a carbon compound to form a carbon sink. The study established a lag model using econometric methods to analyze the cointegration relationship between forest investment and forest carbon storage increment and the Granger causality between the two variables. There is a long-term cointegration relationship between storage increment, but its impact is relatively small, and there is a certain lag period, investment efficiency is low.
