This paper analyzes the problem that the variables that may be encountered in the procurement process of equipment research projects are difficult to measure directly and accurately. A bid evaluation model based on structural equation with 30 evaluation indexes is established, and a set of bid evaluation methods more suitable for equipment scientific research projects is proposed. Through the combination of factor analysis, path simulation test, multi group comparison and causality analysis of structural equation model, the data analysis and processing of the relationship between variables, indicators and variables are realized, and the continuous fitting test makes the model more accurate and effective.
