This paper assesses the Environmental Kuznets curve based on quantile behavior of the relationship between economic growth, forest area, agriculture production, renewable energy, and environmental degradation. The current literature generally used a single indicator to address environmental issues; however single indicator neither measures overall environmental conditions nor does specify that the environment issue is generally diminishing. Our study is the first one that used ecological footprint (EF) as an indicator to test environmental Kuznets curve (EKC) hypothesis for Pakistan by employing recent approach of quantile autoregressive distributed lag (QARDL) initiated by Cho et al. (J Econ 188(1):281-300, 2015). The result of this study validates the EKC hypothesis for Pakistan and shows quantile-dependent relationship, and in that case, using the conventional methods may somewhat lead to biased results. Moreover, the rejection of the null hypothesis of parameter constancy is also confirmed by Wald test. In the long run, the findings of renewable energy consumption and forest area show significant negative effects on ecological footprints, which indicates that by increasing renewable energy usage and forest area, ecological footprints can be minimized. Interestingly, the short-term effects of agricultural production findings on EF show statistically negative results. This illustrates that EF can also be reduced in the agriculture sector by adopting environment-friendly technologies. In order to create efficient policies for environment deterioration, the empirical findings of the current analysis can be used as a guideline for policy implications.
本文基于经济增长、森林面积、农业生产、可再生能源和环境退化之间关系的分位数行为,评估了环境库兹涅茨曲线。现有文献通常使用单一指标来解决环境问题;然而,单一指标既不能衡量整体环境状况,也不能说明环境问题总体上正在减少。我们的研究首次使用生态足迹 (EF) 作为指标,通过采用 Cho 等人提出的最近的分位数自回归分布滞后 (QARDL) 方法(J Econ 188(1):281-300, 2015),检验巴基斯坦的环境库兹涅茨曲线 (EKC) 假说。这项研究的结果验证了巴基斯坦的 EKC 假说,并显示出分位数依赖关系,在这种情况下,使用传统方法可能会导致有偏的结果。此外,Wald 检验还证实了对参数常数性的零假设的拒绝。从长期来看,可再生能源消耗和森林面积的发现对生态足迹有显著的负面影响,这表明通过增加可再生能源的使用和森林面积,可以最小化生态足迹。有趣的是,农业生产发现对 EF 的短期影响显示出统计学上的负结果。这说明通过采用环保技术,农业部门也可以减少生态足迹。为了制定有效的环境恶化政策,当前分析的实证结果可以作为政策影响的指导方针。
