Abstract
Total quantity control is an important means to achieve the goal of building energy conservation in China, but the statistical method of energy consumption data in the production stage of civil building materials has not been established yet. This paper firstly constructs the calculation method of energy consumption in the production stage of civil building materials according to the usage amount of building materials, and then obtains the data of energy consumption in the production stage of civil building materials from 2008 to 2017 according to the statistical yearbook. Then, 30 provinces and cities in China are divided into 3 regions. According to Theil index analysis method, the regional differences of the production energy of China's civil building materials from 2008 to 2017 are calculated. According to the calculation results, China's energy consumption in the production stage of civil building materials shows an overall trend of convergence growth, but the intra-regional difference is greater than the inter-regional difference. The Theil index is the highest in the western region, but the contribution rate of the Theil index is the largest in the eastern region.
