From the angle of digital decorative things, the method of shape identification gives a fresh idea for the study of an evaluation model for innovation and undertaking abilities.Aiming at the problems such as less hierarchical division of traditional methods, combined with the relevant theories such as fuzzy goals and constraints, a fuzzy comprehensive evaluation model based on pattern recognition is proposed. Its adoption of the closeness method can realize the identification of sample category affiliation, thus making the division effect more scientific and reasonable.In the research on weight distribution and the using of the innovation and entrepreneurship ability evaluation system, it is clearly seen that among the indexes of this evaluation system: the importance degrees of the abilities connected with grabbing opportunities are as below, risk taking, organization management, resource integration, innovation ability and professionalism are 0.14, 0.10, 0.15, 0.19, 0.20, 0.24, etc.The assessment results about the innovation and enterprise-starting abilities obtained by the X organization are shown in the following: the overall scores of grasping opportunities,the score points concerning the capacities of grasping chances, undertaking risks, and making innovations are as the following: those for the capacity to bear challenges and make innovations, the overall scores are: 2.4256, 2.8582, 2.7082 The overall situation is just qualified. The overall scores of resource integration, organizational management, innovation ability and professionalism are 3.3616, 3.2630 and 3.1388 respectively, and the overall situation is relatively strong.
