The accumulation of buildings not only causes the consumption various resources, but also generates a large amount carbon emissions. Exploring impact accumulated building materials on emission is great significance for reduction and resource intensive utilization under neutrality. Based linear regression analysis method, coefficient method exploratory spatial data this paper estimated material stock at provincial scale according to nighttime light, visualize its emission, reflect distribution agglomeration. results showed that (MS) (MCE) China’s were 8.8 Gt 17.8 in 2017, respectively. Concrete cement most important MS MCE sources. varied among different regions, determined primarily by urban rural construction land, population, GDP landform. Spatial visualization revealed intensity (MCEI) presented pattern “high southeast, low north middle”, had three aggregation modes. This putted forward new policies low-carbon building, which can help sustainable resources industry.
