The Study About Ecomic Growth And Urbanization Impacting On CO₂ Emiissions Of Our Country

In the 21 st century,along with the rapid development of global economy,our country is also faced with increasingly serious environment pollution problems.The excessive consumption of fossil fuels such as coal,oil and so on rapidly increased CO₂ emissions.At present,our country has become the world’s largest CO₂ emissions entity.In response,at the Copenhagen climate conference,our country made the commitment of “in 2020,our country per unit of GDP CO₂ carbon emission will fall by 40%⁴5% than 2005”.Therefore,we shall research about the influence of economic growth,urbanization on energy consumption CO₂ emissions and establish “low emissions,low pollution,economic and environmental coordinate” economic growth mode,that is important.At first,this paper analyzes the present situation of the economics growth,urbanization,CO₂ emissions,we introduce “Theil index” to study regional differences of our country current productive land area needed for CO₂ emissions（measuring by carbon footprint）.Second,under the background,with the theory of “EKC”,on the basis of time series data in our country from 1971 to 2012 years,we establish cointergration equation,VEC mode: cointergration equation research shows that economic growth and urbanization have a long-term impact of CO₂ emissions,Vector Error Correction equation shows that economic growth and urbanization have a short-term impact on CO₂ emissions,granger causality test reveals the casual relationship among them,impulse response function and variance decomposition analysis show dynamic effect among them.In the end,to make up the shortcoming of times series data,based on the STIRPAT model,we will further research our country’s 30 provinces and cities data in 1995²012 years and divide them into high,medium and low emission zone,at the same time,we build static panel model and spatial panel model,contrast them with each other and quantitatively research the influence of different regional economic growth,urbanization on CO₂ emissions.As an innovation point,this paper introduces the private cars number index to study its impact on CO₂ emissions.The studies show that,at present,China’s CO₂ emissions is continuing to increase,but the corresponding productive land area changed little.Our country’s energy consumption carbon footprint presents regional differences,China’s ecological pressure is increasing one year by one year,and in the most of the provinces and cities,ecological pressure indicators were greater than 1,the current development of our country’s economy still does not meet with the ecological requirement of sustainable development.The reason summarized below: in the short and long term,economic growth and urbanization both have positive effect on CO₂ emissions,and the economic growth effect on CO₂ emissions is the right of parabolic form which is pointing up,it doesn’t have inverted “U” type of Environment Kuznets Curve.Economic growth and urbanization is reinforced each other.Urbanization and economic growth is the granger cause of CO₂ emissions,in turn,it doesn’t hold.In the short term,the economic growth is the main reason causing CO₂ emissions growth,in the long term,the urbanization is the main reason causing CO₂ emissions growth.Based on the each area panel data study found that in the national,high,medium and low-emission zone,economic growth and urbanization will both promote the increase of CO₂ emissions,economic growth has an obvious pull effect on the low emission zone,and urbanization level has an obviously positive effect on the high emission zone.The number of private cars increase,which has an obvious pull impact on the medium area.
