Abstract
The purpose of this paper is to explore the relationships between the construction sector and the rest of the Chinese economy in the energy consumption as it is crucial in energy consumption of the whole economy. Therefore, this paper uses the Modified Hypothetical Extraction Method (MHEM) to quantify the linkages of energy consumption in 2002, 2005, 2007, 2010, 2012, 2015, 2017 and 2018, providing a new perspective for energy consumption linkage studies in China. In this paper we discover the volumes and paths of energy consumption net flows from other blocks to the construction sector and identify the key energy suppliers of the construction sector. The empirical findings show that the indirect energy consumption exceeded the direct energy consumption between 2002 and 2018, representing more than 90% of total (direct plus indirect) energy consumption of the construction sector. Between 2002 and 2018, the indirect energy consumption of the construction sector increased from 27,579 to 111,760 × 104 tons of coal equivalent (tce). We further find that the construction sector has the largest inflows of energy consumption to obtain its own demand than other sectors from 2002 to 2018. The average annual energy consumption net flows from other seven sectors to the construction sector were 1477, 687, 47,998, 6067, 1483, 7362 and 1923 × 104 tce in 2002–2018, respectively. Moreover, we find that the Manufacturing sector is the largest energy supplier of the construction sector between 2002 and 2018.

With increasingly serious global warming, the issue of energy consumption cannot be ignored

It is observed that the energy consumption of Chinese construction sector still experiences a growing trend
Summary
With increasingly serious global warming, the issue of energy consumption cannot be ignored. Energy consumption of construction sector has become a crucial part in global energy consumption [1–6]. Construction sector as the one of the highest energy consumption sectors in China, is the core sector of Chinese energy consumption [7]. According to statistics by National Bureau of Statistics of China, the energy consumption of construction sector in China has increased from 5533 to 9142 × 104 tce (1 tce = 29.3 GJ) during the period between 2010 and 2019, with the average annual growth rate of 6.5%. It is observed that the energy consumption of Chinese construction sector still experiences a growing trend. With the continuous increase of China’s construction scale, the energy consumption of China’s construction sector will continue rising [8–10]
