Abstract: Based on the analysis of the actual statistical data of the product values of five representative imitative innovation projects in time sequence, the growth pattern of the imitative innovation project in the representative aeronautical institution (BIAM) was set up. The model was checked with the actual data. Therefore, the growth dynamics of the imitative innovation project in the aeronautical institution was recognized. It is found that the increase trend of the ratio value of the imitative innovation project income to the total project accords with the Logistic or Comperz curves.
