摘要

在本研究中,我们采用基于莫兰 i 的拉索(Mi-Lasso)方法来解决未指定函数形式的空间依赖性问题,调查国家经济增长与森林砍伐率之间的关联。我们的目的是探索是否存在林业环境库兹涅茨曲线(EKC)。我们处理空间依赖性的方法克服了现有 EKC 文献中发现的局限性。我们估计了 146 个国家从 1990 年到 2020 年的一系列横截面数据模型。我们的研究结果表明了一种非线性关系,揭示了森林砍伐率峰值随时间的变化。此外,我们还发现,森林砍伐率开始下降的收入阈值会随着时间的推移而变化,不同的模型规格之间也存在差异。最重要的是,我们的研究结果表明,如果不考虑空间依赖性,普通最小二乘法(OLS)的收入估计值会出现明显的绝对向上偏差,模型拟合度也会降低。

An environmental Kuznets curve for global forests: An application of the mi-lasso estimator

In this study, we employ a Moran's i based Lasso (Mi-Lasso) methodology to address the spatial dependence of an unspecified functional form, investigating the association between a country's economic growth and the rate of deforestation. Our aim is to explore the existence of a forestry environmental Kuznets curve (EKC). Our approach to handling spatial dependence overcomes limitations identified in existing EKC literature. We estimate a series of cross-sectional data models spanning the period from 1990 to 2020 for 146 countries. Our findings indicate a non-linear relationship, revealing a change peak rate of deforestation over time. Additionally, we observe that the income threshold at which the deforestation rate begins to decrease changes over time with differences observed between model specifications. Crucially, our results highlight that failing to account for spatial dependence leads to a significant absolute upward bias in ordinary least squares (OLS) estimates of income and worse model fit.

期刊介绍: Forest Policy and Economics is a leading scientific journal that publishes peer-reviewed policy and economics research relating to forests, forested landscapes, forest-related industries, and other forest-relevant land uses. It also welcomes contributions from other social sciences and humanities perspectives that make clear theoretical, conceptual and methodological contributions to the existing state-of-the-art literature on forests and related land use systems. These disciplines include, but are not limited to, sociology, anthropology, human geography, history, jurisprudence, planning, development studies, and psychology research on forests. Forest Policy and Economics is global in scope and publishes multiple article types of high scientific standard. Acceptance for publication is subject to a double-blind peer-review process.
