长江经济带城市蔓延及其对碳排放的影响研究

Urban Sprawl in the Yangtze River Economic Belt and Its Impact on Carbon Emissions

本文利用2005年、2010年、2015年长江经济带107个地级及以上城市地均碳排放数据、NPP-VIIRS夜间灯光数据、Landscan人口数据以及统计资料,在计算研究区地级市城市蔓延指数的基础上,基于空间杜宾模型分析城市蔓延对城市碳排放的影响。研究结果显示:长江经济带城市整体呈现蔓延式发展;研究期间,该区城市蔓延对碳排放的影响显著为正,但城市蔓延对邻近城市的碳排放没有显著影响;其余各控制变量对该区碳排放的影响方向及大小各异。

Based on the data of average carbon emission, npp-virs night lighting data, landscan population data and statistical data, this paper analyzes the impact of urban sprawl on urban carbon emission based on spatial Dobbin model based on the calculation of urban sprawl index of prefecture level cities in the study area by using the data of average carbon emission in 107 cities and above cities in the Yangtze River Economic Belt in 2005, 2010 and 2015. The results show that the city of Yangtze River economic belt has a sprawling development;During the study period, the impact of urban sprawl on carbon emission was positive, but the urban sprawl had no significant impact on carbon emission of neighboring cities;The influence direction and size of the other control variables on carbon emission in the region are different.
