Dynamic Correlation between Reduction of Pollution and Carbon Emissions and Economic Growth in the Beijing-Tianjin-Hebei Urban Agglomeration
From the perspective of two-way causality,this paper constructs a panel vector autoregressive model,and combines impulse response analysis and variance decomposition analysis to study the dynamic mechanism of the relationship between the reduction of pollution and carbon emissions and economic growth in the Beijing-Tianjin-Hebei urban agglomeration from 2006 to 2020.The results are shown as follows.① The sustained economic growth of the Beijing-Tianjin-Hebei urban agglomeration has become an important driving force for industrial wastewater and industrial sulfur dioxide emissions.There is a two-way interac-tion between industrial soot emissions and economic growth,and the impact of economic growth on carbon emissions in the Bei-jing-Tianjin-Hebei urban agglomeration is in line with the environmental Kuznets curve.With nonlinear and unstable character-istics,the reverse effect of carbon dioxide on economic growth has not yet reached a significant effect,and the carbon emission reduction mechanism needs to be further improved.⑤ There are"leading effects"and"catch-up effects"between economic growth and pollution reduction and carbon reduction,and a long-term equilibrium relationship is formed.The strong self-inertia of economic growth is the incentive and evolutionary results of the increase of environmental pollutants and carbon emissions.③The implementation of the joint prevention and control policy of air pollution in the Beijing-Tianjin-Hebei urban agglomeration helps to strengthen the two-way interaction between the reduction of pollution and carbon emissions and economic growth.In order to ensure the sustainable development of the Beijing-Tianjin-Hebei urban agglomeration,it is necessary to promote the high-quality development of the regional economy through regional collaborative innovation,green and low-carbon transforma-tion,joint prevention and control.
