For improving the digitalization level in AEC industries, China has widely promoted the adoption and the implementation of smart construction sites. The problems in current stage are focusing on insufficient understandings and lacking enough value due to the smart construction site in China is at the beginning level, which need comprehensive and systematic researches. Therefore, this paper has analyzed and ranked its application value based on the importance by using correlation analysis and factor analysis through the collected data via survey and questionnaires. The highest value in current stage of Chinese smart construction site is the real name registration of the labor. It is commonly agreed that smart construction site has shown its value in different projects. The most important function of smart construction sites in China is the entry identity monitoring based on face recognition, and the research has found that there is little correlation among those functions between different types of smart construction site.Finally, this research has proposed the way to increase the application value in Chinese smart construction site, which can be useful to be implemented real scenarios.
