Emergy Analysis of the Construction Industry System in Xining

Abstract

The rapid development of the construction industry since the 21st century has intensified the contradiction between the use of environmental resources and economic development, and sustainable development is facing severe challenges. In order to coordinate the development of the construction industry’s resource consumption and the eco-economic system, this article uses the emergy analysis method and combines the original data of the construction industry in Xining City from 2011 to 2017 to build a comprehensive analysis of the construction industry system in Xining by constructing an emergy index system. The results show that Xining’s construction industry is more and more dependent on various external energy inputs, and the proportion of local environmental resources it is relying on is getting smaller and smaller, indicating that Xining’s construction industry is more open to the outside world and the more economic development and the quality of life of the people Come the better.
