基于SEM的智慧工地建设制约因素分析及对策研究

随着建设施工的数字化、信息化和智能化，国家提出了智慧工地的理念并得到了一定程度上的应用。但是目前仍存在着诸多问题制约着智慧工地的发展，分析经济、环境、人员、管理、技术这五类因素对智慧工地建设的影响机理，通过文献研究法筛选出20个影响智慧工地建设的制约因素，应用调查问卷收集数据，运用结构方程模型（SEM）对各因素进行评价分析。结果表明，智能设备购买安装使用成本、政府激励扶持政策、标准规范完善度、人才引进和培养、管理制度完善度、管理平台集成化程度对智慧工地建设的影响较为显著，并在此基础上提出相应的对策与建议，为智慧工地在国内的建设及发展提供理论依据。

Analysis and Countermeasure Research on the Restriction Factors of Smart Construction Site Based on SEM

With the digitization，informatization and intelligence of construction，the state has put forward the concept of smart construction site and it has been applied to a certain extent. However，there are still many problems restricting the development of smart construction sites. The influence mechanism of five factors，namely economy，environment，personnel，management，and technology，on construction of smart construction sites is analyzed，and 20 constraints affecting construction of smart construction sites are screened out through literature research. The data were collected using questionnaires，and structural equation modeling （SEM）was used to evaluate and analyze the factors. The results show that the cost of purchasing，installing and using smart equipment，government incentives and support policies，the perfection of standards and norms，the introduction and training of talents，the perfection of management systems，and the integration of management platforms have a significant impact on the construction of smart construction sites. Corresponding countermeasures and suggestions provide a theoretical basis for the construction and development of smart construction sites in China.
