Research On The Coordinated Development Of Industrial Structure And Energy Consumption Structure In The Yangtze River Economic Belt Under The Background Of "Double Carbon"

The report of the Twentieth National Congress of the Communist Party of China put forward that it is imperative to actively and steadily promote the realization of the carbon neutrality goal of carbon peaking,and transform the industrial structure and energy consumption structure.The rapid development of China’s secondary industry consumes a large amount of fossil energy,and the carbon dioxide generated by the combustion of fossil energy poses a serious challenge for China in addressing climate change.Fossil energy has made an important contribution to the rapid development of China’s secondary industries,while the carbon dioxide that accompanies fossil energy consumption has presented China with a serious challenge in combating climate change.The Yangtze River Economic Belt,as a major strategic region in China,spanning the three major plates of east,central and west,is more typical in addressing the challenge of climate change.Therefore,this paper aims to analyze the coordinated development of industrial structure and energy consumption structure of 11 provinces and cities in the Yangtze River Economic Belt under the "double carbon" framework.In this paper,the relevant literature on industrial structure,energy consumption structure,coordination theory and carbon peaking and carbon neutrality is firstly reviewed.Then,the current situation of these three aspects in eleven provinces and cities in the Yangtze River Economic Belt is analyzed.By using unit root tests and co-integration tests to examine whether a long-term equilibrium relationship exists among these three aspects,and to set the stage for further research on the current situation of the coordinated development of industrial structure and energy consumption structure in the Yangtze River Economic Belt.Secondly,this paper constructs a model to evaluate the Coupling Degree between the energy consumption structure and the industrial structure.The comprehensive scores of the two and the Coupling Degree of the two are calculated in 11 provinces and cities.The results show that the comprehensive scores of the two are generally increasing,and the ranking order of the average scores is generally distributed according to the lower,middle and upper reaches of the Yangtze River.On the one hand,the Degree of Coupling between the two pairs has been on the rise over time.On the other hand,Shanghai has reached a state of high quality coordination,Zhejiang is in good Coupling Degree,and all other provinces and cities are in intermediate coordination and below from the spatial dimension.Subsequently,the panel data of 11 provinces and cities in the Yangtze River Economic Zone were quantitatively analyzed by Feasible Generalized Least Squares.From the perspective of the full sample,an increase in the coupling degree of industrial structure and energy consumption structure will suppress CO2 emissions and emission intensity,and have a greater impact on the intensity of carbon emissions.Energy consumption has a significant positive effect on carbon emissions,while population density is negatively related to carbon emissions.In terms of heterogeneity,provinces and cities with a poor coupling degree can reduce CO2 emissions by increasing their per capita income or energy efficiency,i.e.by developing public transport or increasing the efficiency of heating and cooling mechanisms in multi-family housing.Provinces with a better coupling degree can reduce carbon emissions according to the characteristics of their energy sources,for example,Sichuan and Chongqing can improve the proportion of wind and hydro renewable energy,while areas such as Jiangsu and Anhui can develop photovoltaic technology to strengthen their energy mix.In short,it is necessary for different provinces and cities to adopt different methods to reduce their total energy consumption.Lastly,based on the results of the analysis,the study proposes some policy recommendations to effectively promote the development of China’s coupled and coordinated energy consumption structure and industrial structure in four fields: policy and market power,optimization of industrial structure and adjustment of energy consumption structure,and strengthening of energy conservation and emission reduction in enterprises.
