Research On The Influencing Factors Of BIM Technology Adoption Based On UTAUT Model

Under the background of comprehensively promoting the informatization of the construction industry and accelerating the transformation and upgrading of the industry,Building Information Modeling(BIM),as a key means to realize informatization in the industry,has become the focus of attention of all parties in the construction industry.However,due to various reasons,the adoption of BIM Technology in Chinese enterprises is not high.Therefore,it is necessary to study the factors affecting the adoption of BIM Technology.Firstly,this paper reviews the research status of BIM Technology Promotion and adoption,and expounds and analyzes the concept,application value and it adoption theory of BIM Technology.This paper studies BIM Technology adoption from the perspective of enterprises,takes the Unified Theory of Acceptance and Use of Technology model(UTAUT)as the theoretical basis,combines the characteristics of Bim and literature analysis,selects four new variables,namely perceived cost,attitude of top managers,compatibility and enterprise innovation,and adds them to the original model,and puts forward the hypothesis of the relationship between factors,forming a BIM Technology Adoption Model Based on UTAUT model,and then makes a questionnaire.The reliability and validity of the questionnaire were tested,and the structural equation model was used to verify the relationship hypothesis.The conclusion is that the willingness of enterprises to adopt BIM Technology is not only affected by four variables in the model,but also affected by perceived cost,attitude of top managers and enterprise innovation.The hypothesis that compatibility has a positive effect on BIM adoption behavior is not tenable.In addition to the perceived cost,the other variables have a significant positive impact on BIM adoption intention,and the contributing factors have a direct positive impact on BIM adoption behavior.The order of the influence degree of BIM Technology adoption intention is: Social Influence > Performance Expectancy > Manager Attitude > Effort Expectancy > Perceived Cost > Enterprise Innovation.The order of the influence degree of BIM Technology adoption behavior is: Adoption Intention > Facilitating Conditions.According to the results,this paper puts forward suggestions from three aspects of government departments,enterprises themselves and software manufacturers to promote enterprises to adopt BIM Technology.The innovation of the research lies in the application of technology adoption theory to BIM Technology Adoption and the expansion of the original UTAUT model.At last,the paper points out the shortcomings and prospects.
