Dynamic Evolution Analysis of Spatial Differences of Carbon Emissions in Beijing-Tianjin-Hebei Region from 1997 to 2017

\nCarbon emission is the main cause of climate change, and Beijing-Tianjin-Hebei (BTH), is one of the main region of carbon emission in China. In order to study the carbon emission characteristics in the BTH region, this paper uses the Geostatistical method to analyze the dynamic evolution of the spatial variations of carbon emissions from 1997 to 2017. (1) The global Moran’s I analysis indicates that carbon emissions take on a spatial agglomeration effect in BTH region. The global Moran’s I show a decreasing trend from 1997 to 2012, indicating that there is gradually weakening pressure between cities. However, from 2012 to 2017, the global Moran’s I show an increasing trend, indicating that there is gradually strengthening pressure between cities. (2) The hotspot areas have remained largely unchanged except Beijing. Beijing has transitioned from a hotspot area to a non-hotspot area. (3) Standard deviational ellipse analysis showed that that the carbon emission distribution in the BTH region basically exhibits a northeastsouthwest distribution pattern and has a very small variation.\n
