Abstract
China’s construction industry emits a huge amount of carbon dioxide with the extensive and rapid development, and the carbon dioxide emissions from construction sector have become a social problem. This article evaluates the carbon dioxide emission from China’s regional construction industry by the three-stage DEA method. The research results indicate that the environmental factors and random error seriously affect the carbon dioxide emission efficiency of construction industry. Eliminated the above factors, the mean of the carbon dioxide emission efficiency has the tendency of rising firstly and then decreasing, which increased from 0.67 in 2010 to 0.76 in 2014 and then decreased to 0.66 in 2019 in the third stage. On the whole, China’s regional construction industry has the low carbon dioxide emission efficiency. In the regions, the Eastern region has the highest technology efficiency value among the three regions, followed by the Middle region and the West region. Therefore, the key method to increase the carbon emission efficiency of construction industry is to improve the management efficiency and change the growth mode.
Highlights
Introduction e construction industry ofChina has a dramatic improvement in recent years. e gross annual value of construction industry has increased from 138.2 hundred million Yuan in 1978 to 248443 hundred million Yuan in 2019.ere are 54 million workers employed in construction industry, accounting for 6.69% of the total employed in China [1]. e construction industry drives the development of related industries
Wang et al [33] collected the data to estimate the difference of environmental efficiency in top 20 Asian economies, the results indicated that Japan did the best in energy efficiency than others and was a good example to protect environment
While the pure technical efficiency (PTE) ranges only from 0.72 to 0.81 in the years between 2010 and 2019, the lower technology efficiency (TE) and pure technology efficiency (PTE) restricts the carbon dioxide emission efficiency of all regions. This analysis includes the interference of environmental factors and random factors, which cannot reflect the real technical efficiency of carbon dioxide emission in various regions, so it needs to be further adjusted and recalculated
Summary
Coke 0.855 e factor of carbon dioxide emissions of important building energy (tc/tce). The greater output from construction industry is. E rapid urbanization in China stimulates the demand for housing and infrastructure and absorbs many labor forces into the construction industry. E study selected 30 provinces data of construction industry from 2010 to 2019 as sample. Due to the missing of data, the Tibet Autonomous Region are unselected. Every region is considered as a DMU to estimate the carbon dioxide emission efficiency changing in China’s construction industry. All data in this article are from China statistical yearbook on construction (2011–2020), China statistical yearbook (2011–2020), and China statistical yearbook on energy (2011–2020). Variables measured in money in the article are adjusted by the Consumer Price Index (CPI) in 2011 to eliminate the influence of inflation
