Research On BIM Technology Adoption And Application Strategy Based On TAM-TOE Model

The construction industry has made great contribution to the economic growth and social development,but it also faced with many problems such as serious waste of resources and low efficiency of production.Its overall development level is still relatively low.With the development and progress of society,the project which has complex construction process,massive investment,numerous participating units,huge amount of information is constantly emerging.The appearance of the Building Information Model(BIM)provides a way to solve the problems in the construction industry and also makes it more smoothly to implement the complex projects.Although BIM has been widely recognized,the level of adoption and application of enterprises is still relatively low.Therefore,it is necessary to study the factors that influence the adoption of BIM.Firstly,this paper systematically expounds the theory of BIM and the Technology Acceptance Model,according to the characteristics of BIM application and the advantages and disadvantages of each technology acceptance model,applies the revised TAM-TOE model to the research of enterprise BIM adoption.This paper identifies 4 categories of factors,including environmental factors,technical factors,organizational factors and economic factors,and 12 external factors that influence the adoption of BIM,constructs the initial TAM-TOE model of BIM,and makes questionnaire to investigate.Then the interval number DEMATEL method is used to calculate the collected data to get the comprehensive influence degree of each factor,so as to draw the TAM-TOE model of the enterprise adopting BIM.Then obtain the influence degree,the influenced degree,the center,and the reason degree of BIM adoption.Taking the reason degree 0 as the dividing line,and get 9 reason factors whose reason degrees are greater than 0,with 8 of which have strong driving forces;and get 6 target factors whose reason degrees are less than 0,including 5 target factors whose center degrees are relatively high.Finally,the simulation analysis is carried out with 8 reason factors which have strong driving forces as independent variables and 5 target reasons whose center degree is relatively high as dependent variables,and obatained the effect of the reason factors on the target factors.According to the influence of the reason factors on the target factors,the reason factors are sorted and classified.This paper puts forward the corresponding solutions for these four kinds of factors,such as environmental factors,technical factors,organizational factors and economic factors,which has a certain reference value to promote the adoption and application of BIM in China.
