Research On The Influencing Factors Of Construction Cost Management Under The Background Of Refined Management

At present,the construction technology level of China's construction enterprises is in the forefront of the world,and the construction technology system has developed from the initial stage of exploration to a more mature stage,but there are still problems such as organizational chaos and backward concept in cost management,which seriously weaken the core competitiveness of enterprises.With the improvement of project contract price transparency and the intensification of market competition,more and more construction enterprises attach importance to refined cost management.Based on the perspective of delicacy management,this paper studies the influencing factors of cost management from the construction preparation stage to the completion acceptance stage,so as to provide reference for construction enterprises to improve construction cost management.Firstly,the purpose and significance of the research were determined based on the background of the current construction industry,and some domestic and foreign literatures on construction cost management and delicacy cost management were reviewed.Then,the research methods and ideas of this paper were determined.Secondly,the concepts and research methods of cost management and delicacy management are introduced.The cost management part includes the construction cost,construction cost management concept and construction cost management method.The elaboration management part elaborates the elaboration management concept,the characteristic and carries on the elaboration management necessity.The research method mainly introduces the related concepts and analysis steps of factor analysis and structural equation model.Thirdly,the influence factors of construction cost management are analyzed.Firstly,the acquisition principles,sources and preliminary determination of the influencing factors of construction cost management are expounded.Secondly,the questionnaire design is introduced.Finally,the reliability and validity analysis of the data obtained from the questionnaire is carried out with the help of SPSS.Fourthly,the structural equation model of construction cost management is analyzed.Firstly,factor analysis was carried out on the sample data with the help of SPSS,and the potential variables needed for structural equation modeling were determined according to the factor rotation load matrix table,factor variance contribution rate table and factor analysis gravel diagram.Then,the structural equation is preliminarily modeled and evaluated,and the model is modified according to the output of AMOS.Finally,according to the standardized path coefficient of the structural equation model,the influence degree of the construction cost management factor potential variables and the observation variables and the influence relationship between the potential variables are analyzed.It is found that field professional management has the greatest impact on construction cost,which is significantly higher than other potential variables.Finally,through the analysis of the results,put forward the relevant countermeasures and Suggestions on how to improve the construction cost management effect.It mainly includes four aspects: talent management,optimization of organizational structure,improvement of construction site management,and improvement of adaptability to external environment.
