金砖国家在经济增长过程中出现的不合理碳排放具有典型的负外部性特征,要通过政府强干 预进行控制。本文延续EKC理论研究路线,利用半参数回归模型对金砖国家环境质量与经济发展间 的互动关系进行研究,并通过引入相关控制变量确定引发不合理碳排放的主要影响因素,探索促进 金砖国家经济与环境协调发展的有效路径。研究结果表明:大部分金砖国家在环境质量与经济增长 之间存在脱钩现象;产业结构、城镇化和能源消耗等方面存在的不科学性降低了环境质量;推动可 持续发展对改善环境质量和经济发展有促进作用。政策建议是金砖国家要高度重视经济发展的质量 与生态保护工作,通过采取加强低碳技术研发与应用的财政投入力度、推动生态文明建设、加强国 际合作、加大监督与执法力度等措施提高政府治理的有效性和推动可持续发展。
Unreasonable carbon BRICS appear in the process of economic growth in the emission of the negative externalities of the typical characteristics, needs under the government strong interference can be effectively controlled. In this paper, we study the relationship between environmental quality and economic development of the BRICS by using the semi parametric regression model, and explore the effective path to promote the coordinated development of economy and environment in the BRIC countries by introducing relevant control variables to determine the main influencing factors of EKC. The results show that: most of the BRIC countries in the environmental quality and economic growth in the presence of decoupling phenomenon; due to the industrial structure, urbanization and energy consumption and other aspects of the existence of irrational phenomenon to reduce the environmental quality; The promotion of sustainable development helps to improve environmental quality and promote economic development. The policy recommendations of this research is that the BRICS should pay more attention to the quality of economic development and energy saving and emission reduction work, and should adopt the strong low-carbon technology development and application of financial investment, promote the construction of ecological civilization, strengthen international cooperation, strengthen supervision and law enforcement efforts and other measures to achieve sustainable development goals.
