The present study empirically investigates the impact of hydropower energy consumption on economic growth and CO emissions in China, spanning the period 1965-2016. Using the ARDL bounds testing approach to cointegration, this study confirms the existence of a long-run relationship among the variables. Moreover, hydropower energy consumption has a positive impact on economic growth, while CO emissions have a long-run negative impact on economic growth. However, economic growth and CO emissions have a positive impact on hydropower energy consumption. Further, the study failed to provide a support of the environmental Kuznets curve (EKC) hypothesis for China. The Granger causality test reveals that there is a unidirectional causality running from hydropower energy consumption to economic growth. Furthermore, there is a bidirectional causality among the hydropower energy consumption, economic growth, and CO emissions in the long run. Given these findings, we argue that hydropower energy consumption is considered as the driving force to enhance the economic growth in China.
本研究实证考察了 1965-2016 年期间水力发电能源消费对中国经济增长和二氧化碳排放的影响。利用 ARDL 边界检验方法进行协整检验，本研究证实了变量之间存在长期关系。此外，水力发电能源消费对经济增长具有正向影响，而二氧化碳排放对经济增长具有长期负向影响。然而，经济增长和二氧化碳排放对水力发电能源消费具有正向影响。此外，本研究未能为中国的环境库兹涅茨曲线（EKC）假说提供支持。格兰杰因果检验表明，水力发电能源消费与经济增长之间存在单向因果关系。此外，在长期内，水力发电能源消费、经济增长和二氧化碳排放之间存在双向因果关系。鉴于这些发现，我们认为水力发电能源消费被视为中国经济增长的推动力量。
