The link between CO2 emission and its possible determinant, namely financial development, foreign direct investment, economic growth, and energy consumption, gives a significant environmental research place. This study attempts to determine the nonlinear link between CO2 emissions and its determinants in China for the period 1985-2019. Based on the theoretic links and foundation, we develop an asymmetric autoregressive distributed lag (ARDL) model using annual data in this study. The findings of the nonlinear ARDL suggest that domestic credit from the banks (DCB) has a negative effect on environmental pollution in the short and long run, while domestic credit to the private sector (DCP) has an insignificant negative role in environmental pollution in China. The results show that positive change in DCB causes a decrease in CO2 emissions, while negative change increases it in the short and long term. The coefficient for a positive shock in DCP is a negative, and negative shock in DCP has a significant positive impact on environmental pollution in the short and long run. This means that nonlinear ARDL financial development effects on environmental pollution have deviated from the linear ARDL estimates. Empirical findings also support the presence of asymmetric long-run cointegration among the indicators. The findings also show that energy consumption and real GDP have a significant positive impact on CO2 emissions in the long-run, while foreign direct investment (FDI) improves the environment. Based on the empirical findings, the study endorses the suitable channelization of the finance market towards clean energy projects without compromising economic growth.
二氧化碳排放及其可能的决定因素(即金融发展、外国直接投资、经济增长和能源消耗)之间的联系为环境研究提供了重要的研究方向。本研究试图确定中国 1985-2019 年期间二氧化碳排放及其决定因素之间的非线性关系。基于理论联系和基础,我们使用年度数据在本研究中开发了一种非对称自回归分布滞后 (ARDL) 模型。非线性 ARDL 的结果表明,银行国内信贷 (DCB) 在短期和长期内对环境污染都有负面影响,而国内对私营部门的信贷 (DCP) 在短期内对环境污染的影响并不显著,在长期内则为负面影响。结果表明,DCB 的正向变化会导致二氧化碳排放量减少,而负向变化则会在短期和长期内增加。DCP 的正冲击系数为负,而 DCP 的负冲击对环境污染的影响在短期和长期内均为显著正向。这意味着金融发展对环境污染的非线性 ARDL 效应偏离了线性 ARDL 估计。实证结果也支持各指标之间存在非对称长期协整关系。研究结果还表明,能源消耗和实际 GDP 对 CO2 排放有长期的显著正向影响,而外国直接投资 (FDI) 则改善了环境。根据实证结果,本研究支持将金融市场适当地引导到清洁能源项目上,同时不影响经济增长。
