Abstract

This study examined the nexus between energy consumption and environmental quality in light of China's 2060 carbon-neutrality agenda utilizing annual frequency data from 1971 to 2018. In order to obtain valid and reliable outcomes, more robust econometric techniques were employed for the analysis. From the results, all the variables were first differenced stationary and cointegrated in the long-run. The elastic effects of the predictors on the explained variable were explored through the ARDL, FMOLS, and the DOLS techniques, and from the discoveries, energy utilization worsened environmental quality in the country via more CO emissions. Also, industrialization and urbanization deteriorated the country's environmental quality; however, technological innovations improved ecological quality in the nation. On the causal connections between the variables, a unidirectional causality from energy consumption to CO effluents was discovered. Also, feedback causalities between industrialization and CO secretions, and between urbanization and CO exudates were disclosed. However, there was no causality between technological innovations and CO emanations. Based on the findings, the study recommended among others that, since energy consumption pollutes the environment, the country should transition to the utilization of renewable energies. Also, the government should allocate more resources to the renewable energy sector. This will help increase the portion of clean energy in the country's total energy mix. Furthermore, research and development that are linked to the utilization of green energies should be supported by the government. Data constraints were the main limitation of this exploration. Therefore, in the future, if more data become available, similar explorations could be conducted to check the robustness of our study's outcomes.

摘要

本研究利用 1971 年至 2018 年的年度频率数据,根据中国 2060 年碳中和议程,考察了能源消耗与环境质量之间的关系。为了获得有效和可靠的结果,我们采用了更稳健的计量经济学技术进行分析。结果表明,所有变量在长期内均经过一阶差分平稳和协整检验。通过 ARDL、FMOLS 和 DOLS 技术,探讨了预测变量对解释变量的弹性影响,从中发现,能源利用通过更多的 CO 排放恶化了该国的环境质量。此外,工业化和城市化恶化了该国的环境质量,但技术创新提高了国家的生态质量。在变量之间的因果关系方面,发现能源消耗对 CO 排放有单向因果关系。此外,还揭示了工业化和 CO 排放之间、城市化和 CO 排放之间存在反馈因果关系,但技术创新与 CO 排放之间没有因果关系。基于这些发现,本研究建议,由于能源消耗会污染环境,该国应向可再生能源的利用转型。此外,政府应向可再生能源部门分配更多资源。这将有助于提高清洁能源在该国能源结构中的比重。此外,政府应支持与绿色能源利用相关的研发。数据限制是本研究的主要局限性。因此,在未来,如果有更多的数据可用,类似的研究可以进行,以检查我们研究结果的稳健性。
