Research On Temporal And Spatial Migration Of Energy Consumption Carbon Footprint And Its Influence Factors In China

With the convening of the annual global climate conference,global climate change has gradually become the focus of the current international community,governments continue to emphasize energy conservation and environmental protection,the development of low-carbon economy is an inevitable trend."Kyoto Protocol" is signed so that developed countries and developing countries in the international community to undertake emission reduction obligations.China is the largest developing country in the world,In science and technology,we have a long way to catch up with the developed countries,Economic development needs to rely on the traditional energy,environmental issues and energy crisis are currently to be resolved.China is a country with large energy consumption,in the global context of low-carbon emission reduction,China has an obligation to develop friendly-environment.Based on the above factors,this study estimated the carbon footprint of the 30 provinces in China based on the energy consumption.From the views of time evolution and spatial distribution,this paper analyzes the spatial and temporal migration of the provincial carbon footprint.And based on the STIRPAT model and the EKC curve,this paper illustrated influence factors of the carbon footprint of China’s energy consumption.The empirical results show that:Firstly,The carbon footprint of our country is the most in the world,and environmental pressure problems need to be resolved.From 2003 to 2014,the growth rate of China’s total carbon footprint is 557%,the average annual change intensity is 25.96%,the carbon footprint of the province’s carbon footprint growth has obvious differences and gradually expanded.There is a autocorrelation in the space of carbon footprint,which shows the obvious agglomeration characteristics.The influence of the carbon footprint of the area is not only from itself but also closely related to the surrounding area.In the spatial distribution,the carbon footprint of the eastern region is higher than that of the western region,but the difference between them is gradually decreasing.Secondly,the empirical results based on the STIRPAT model show that the impact on the environmental pressure from high to low is the number of population,the proportion of secondary industry,the proportion of tertiary industry,high-tech industry,per capita GDP.The population has the greatest impact on the carbon footprint,with elasticity as high as14.8867.Overall,China’s eastern population is higher than the west,and its production and living rely on energy is also increasing with the increase in environmental stress.China’sper capita GDP increased by 1%,carbon footprint increased by 0.5188%.In the spatial distribution,per capita GDP of the eastern coastal provinces and cities is higher than that of the inland areas,and the former contributes to the carbon footprint more than the latter.In general,per capita GDP is an important factor in the carbon footprint,and it also increases the unevenness of the spatial distribution.The proportion of the second industry increased by one percentage point,carbon footprint decreased by 2.0846 percentage points,which means that the higher the proportion of secondary industry,the greater the role of emission reduction.High-tech industry accounted for the impact of environmental stress is positive,the elastic coefficient of 1.4267.At present,China’s high-tech industry research results are really few used to enhance environmental quality,but it can increase the environmental pressure.Based on the above analysis,the regional differences of carbon footprint are becoming more and more prominent,and the inter-regional interaction,population,wealth,technology and other factors have a certain impact on spatial differences.Thirdly,the impact of per capita GDP on the carbon footprint of the smallest,which has elasticity of 0.5188,the relationship between environment and economic development has gradually weakened.Based on the environmental Kuznets analysis,this study explores the relationship between per capita carbon footprint and per capita GDP,and the empirical results show that there is an "N" curve relationship between the two.
