Based on China High Resolution Emission Gridded Data (CHRED), the spatial pattern and agglomeration characteristics of carbon dioxide emissions in Beijing-Tianjin-Heibei region and Yangtze River Delta region are analysed by means of exploratory spatial data analysis techniques (ESDA) and spatial regression model. By mean of significant test, we explore the spatial lag regression (SLM) and spatial error regression (SEM) method to reveal the influence factors of carbon emissions in urban agglomeration. The carbon emission in Beijing-Tianjin-Hebei region proves to be more in spatial randomness and structural instability with index of Moran's I value -0.131. However, the spatial agglomeration effects in the Yangtze River Delta region are obvious with index of Moran's I value 0.106 that neighbour regions pose great effect on carbon emissions. Population and economic factors are the main influence factors of carbon emissions in above mention two urban agglomerations. In general, the diffusion effect of carbon emissions in the Yangtze River Delta region proves to be more apparently. However the agglomeration effect of carbon emissions in Beijing-Tianjin-Heibei region is still obvious. Turning to multicentre of regional development is one of the important measure to solve the metropolitan malaise. And metropolitan region should strengthen the object control of divergent effect of carbon emissions, promote the integration of low-carbon development, and achieve regional carbon emissions balance.
