Construction enterprise is one of the subjects in the construction of social credit system.Good construction enterprise credit plays an important role in the sustainable and healthy development of the construction market.The construction of credit system in China’s construction industry is in the development stage,and construction enterprise still have dishonesty in construction market trading activities.Therefore,forcing construction enterprises to improve their credit level and standardize their own behavior through scientific and effective credit evaluation is of great significance to promote the harmonious development of the construction industry and create a healthy and orderly atmosphere in the construction market.Firstly,build an evaluation index system based on the credit characteristics of construction enterprises,take the actual performance of construction enterprise in the construction market as the key points of indicators,and improve and expand the quantitative standards of qualitative indicators.Secondly,in view of the limitations of subjective weight determination and the high-dimensional attributes of evaluation data in the common credit evaluation methods of construction enterprise,an evaluation model based on projection pursuit method is constructed.The best projection direction and credit projection value are obtained by using the firefly algorithm to solve the model,and Fisher optimum partition method is used to achieve credit classification.Finally,taking10 listed construction enterprises as samples,and the key factors affecting the credit of construction enterprise and the credit classification scheme of sample enterprises are obtained,which verifies the applicability and feasibility of this model.Credit evaluation of construction enterprise can provide a decision-making basis for construction units to choose construction enterprises with high quality credit,provide information for relevant departments to implement credit classification supervision of construction enterprises,and can also provide ideas for construction enterprises to formulate strategies to improve their credit level.Figure 6;Table 9;Reference 62... |
