Study On The Energy Production,Economic Growth And Carbon Emission In China

The rapid development of a country's economy is often inseparable from the large amount of energy consumption.Since the reform and opening up,China's rapid development of society and economy,the demand for energy has also increased,and excessive consumption of energy has caused excessive carbon emission,greenhouse effect and other environmental problems are becoming more prominent.As a clean energy source,renewable energy has the advantages of wide distribution,large development potential,pollution-free and sustainable use compared to non-renewable energy.For the harmonious development of man and nature,the Chinese government has recognized the importance of energy conservation,emission reduction,and vigorous development of renewable energy from many aspects,such as scientific and social development,and has begun to actively respond.In the coming period,renewable energy will be in a rapid development stage,and its share of energy consumption will increase rapidly.The gradual transition from non-renewable energy to renewable energy is not only the trend of China's energy development but also the trend of world energy development.Firstly,we introduce carbon emission into the energy production economic growth model and build a energy production economic growth carbon emission model.The dynamic evolution of the relationship between China's renewable energy production,non-renewable energy production,economic growth and carbon emissions is analyzed by using the dynamic system theory.The existence of Lyapunov exponential spectrum and chaotic attractor reveals the complex dynamic relationship of energy production economic growth carbon emission model.Then the energy production economic growth carbon emission model that have been empirically analysed is used to analyze whether China can achieve the 2020 carbon emission target.Finally,the game theory is used to construct an energy game model to solve the equilibrium output of renewable and non-renewable energy in the energy market,and the effects of tax rate and subsidies on the equilibrium output are analyzed.We get the following conclusions:1.Using the parameter-identified energy production economic growth carbon emission system to calculate GDP and carbon emissions in 2020,China's carbon emission per unit of GDP decreased by 58.9% on the basis of 2005 in 2020.It shows that China can achieve the commitment made at Copenhagen Conference to reduce carbon emission per unit GDP by 40-45% by 2020 on the basis of 2005 under the condition of simulation.2.Non-renewable energy production decreases with the increase of tax rate,showing a monotonous decreasing relationship.Renewable energy increases with the increase of tax rate,showing a monotonous relationship.The output of non-renewable energy decreases with the increase of subsidies,showing a monotonous decreasing relationship.Renewable energy increases with the increase of subsidies,showing a monotonous relationship.The government can intervene in non-renewable and renewable energy production through macro-regulation of tax rates and subsidies,so as to alleviate the greenhouse effect and achieve sustainable energy development.The innovation of this paper is to establish a energy production economic growth carbon emission model to discuss the dynamic relationship between non-renewable energy production,renewable energy production,economic growth and carbon emission.At the same time,the parameters of the constructed model are identified by genetic algorithm,and whether the carbon emission intensity target of China can be achieved is discussed.
