The Impact Of Urban Population Scale On Energy Consumption

With the increasing attention to global warming,the relative energy consumption have also become an important issue of academic and social concern.The balance of energy consumption depending on the size of the population,and the eventual impact on carbon dioxide emissions,is also one of the current concerns.By constructing relevant mathematical models,this paper proves that population size has a positive effect on the improvement of energy consumption efficiency and the increase of total social output in mathematical logic.Based on the relevant data of all 21 cities in guangdong province from 2006 to 2015,using the fixed panel regression analysis model and spatial autoregressive model,proved the result of the mathematical model,and found that,although a larger populations would increase energy efficiency to a higher equilibrium,it also leads to a larger output,and the impact of a larger population size on output is bigger than it has on energy efficiency.Eventually,total energy consumption is larger in a larger population.Using relevant data of “42 departments in guangdong in 2012 input-output table”.By building social accounting matrix and establishing a computable general equilibrium,this paper simulated the energy consumption level in different urban population,and found that in the case of a larger population,the equilibrium level of the overall energy consumption will indeed significantly increased,and the extent of increase is greater than the population change,that means although a larger population can lead a smaller unit GDP energy consumption,but a largher per capita energy consumption.
