The Research On How The Urbanization Rate And Its Spatial Spillover Affect The Amount Of Carbon Dioxide

Greenhouse gas emissions and the acceleration of the urbanization process are at the center of attention.how to develop urbanization and reduce carbon emissions is an urgent problem to resolve.Economic development has led to rapid urbanization rate in China,and urban industrial development is in a smooth and orderly manner.The acceleration of urbanization,the improvement of urban industrialization,the construction of infrastructure,and the increase in energy demand,have result in the increase in carbon emissions.Gradually,the environmental problems caused by the carbon emissions also aroused people's attention.The progress of urbanization also encourages the development of technology,so that the amount of carbon emissions reduced.By the end of 2014,China has become the world's biggest carbon emissions country.So analyzing the impact of urbanization on China's carbon emissions is conducive to promoting the steady and rapid development of China's economy.It also helps to optimize China's industrial structure and further increase the income of residents and improve the quality of life,so as to enhance China's comprehensive national strength.Built on the data of 28 provinces in China from 1995 to 2014,this literature constructs static panel,dynamic panel and spatial panel STIRPAT model to verify the impact of urbanization on China's carbon emission.The main research contents are as follows: Firstly,this literature studies the ways of urbanization impact on carbon emissions,that is clarifies how the urbanization affect carbon emissions;Second,with the descriptive analysis the author explains China's urbanization and carbon emissions condition;Thirdly,the static panel model,the dynamic panel model and the spatial panel model are used to demonstrate whether the urbanization and carbon emissions in China have inverted "U" type relationship to demonstrate if population factors,per capita GDP factors and energy consumption intensity factor have impact on carbon Emissions;Fourth,by comparing the results of static panel model,dynamic panel model and spatial panel model,the turning points of urbanization and carbon emission are calculated,and the model that can best fit the data is selected.The empirical study shows a significant linear relationship between population factors,per capita GDP factors,energy consumption intensity factors and carbon emissions.There represents an inverted "U" relationship between urbanization rate and carbon emission.In the initial stage of urbanization,the increase of urbanization rate leads to a significant increase in carbon dioxide emissions.In the later stage of urbanization,the urbanization rate increase results in a significant reduction in carbon dioxide emissions.There is a spatial "spillover effect" between urbanization and carbon emissions and there is an inverted "U" relationship between a province's urbanization rate and its neighboring province's carbon emission.That is to say,in the early stage of urbanization,the increase of urbanization in a province leads to a significant increase in carbon emissions in the neighboring provinces.In the later stage of urbanization development,the increase in urbanization leads to a significant reduction in carbon emissions in the neighboring provinces.China needs to speed up the process of urbanization and promote rapid and steady economic progress,so the increase in energy demand cannot be avoided.Carbon emissions continued to increase all the time.Under such circumstances,we should change the current economic development mode,optimize the structure of the industry,and speed up technological innovation.And we also should reduce the consumption and consumption intensity of fossil fuels and control the rapid population growth trend,so as to achieve rapid development of the urbanization,in achieving the target of continuous reduction of carbon dioxide.
