[Abstract]:At present, the evaluation method of niche suitability has been widely used in many fields, its application value is gradually accepted by the society, but its theoretical research is still in its infancy. There are few research results and many theoretical problems need to be deepened. In this paper, the ecological niche suitability evaluation method is explored in the innovation ecology based on the theory of innovation ecosystem. Application problems in the system: an innovative ecological factor assignment method based on intuitionistic fuzzy sets is proposed, which emphasizes the ecological characteristics of ecological factor assignment, and an innovative niche suitability evaluation method based on intuitionistic fuzzy sets and interval intuitionistic fuzzy sets is proposed, and a new method of evaluating static niche suitability with intuitionistic fuzzy set distance is explored. The dynamic evaluation method of innovation niche suitability based on time intuitionistic fuzzy sets is proposed, and the new method of dynamic niche suitability evaluation based on the similarity measure of intuitionistic fuzzy sets is explored. The innovation niche suitability evaluation model constructed in this paper is used to solve the problem of creative niche evaluation in reality. The main research content of this paper is the main research content of the thesis. Including: (1) the background and significance of this study, research status at home and abroad, research purposes, methods, content and logical framework and innovation. (2) the theory of innovation ecosystem, niche suitability evaluation theory and the comprehensive evaluation theory based on intuitionistic fuzzy sets are combed, and (3) research based on intuitionistic model First, the meaning of extreme value type (extremely large or extremely small) and restrictive innovation ecological factors under intuitionistic fuzzy information and the transformation method are proposed. Secondly, the ecological niche model theory is used to construct the innovative ecological factor Fu based on the niche priority model and the segmentation line segment model. The value model of the innovative ecological factor with definite ecological significance is given. Thirdly, the weighting weight of the extreme value innovation ecological factor is determined by the true membership point and the false membership point, and the valuation weight of the restricted innovation ecological factor is determined by the hesitation point, and the innovative ecological cause with the characteristic of intuitionistic fuzzy information is given out. In the end, an innovative ecological factor assignment model based on linguistic information preference is given. (4) a static evaluation method of innovative niche suitability based on intuitionistic fuzzy sets is studied. First, the definition and measure method of intuitionistic fuzzy hyper volume ecologic niche are given. Secondly, an innovative niche fitness based on Intuitionistic Fuzzy sets is constructed. The basic method of evaluation is to establish an ecological factor weighting method based on the weighted average operator of hesitation degree (PI -OWA operator), determine the niche optimal value by using the intuitionistic fuzzy set operation rules, and establish an evaluation model based on the distance measure of intuitionistic fuzzy set and the evaluation process of the method. Finally, the construction is based on the interval straight. The innovation niche suitability evaluation method of the sense fuzzy set, which uses the interval intuitionistic fuzzy set operation rules to determine the niche optimal value, establishes an suitability evaluation model based on interval intuitionistic fuzzy set distance measure. It provides a new model for the innovative niche suitability evaluation method. (5) research based on the time intuitionistic fuzzy set. The dynamic succession of the new niche suitability is considered. Considering the dynamic succession of the innovative ecosystem and the time intuitionistic fuzzy sequence of the ecological factors, the dynamic stability of the innovation niche suitability is evaluated. Firstly, the weakening buffer operator in the grey system theory can effectively weaken the ecological factor time of the external resources of the new ecosystem. The impact disturbance of the intuitionistic fuzzy sequence avoids the distortion of the time intuitionistic fuzzy sequence because of interference and ensures the correctness of the evaluation results. The weighted arithmetic average weakening buffer operator (TVWAWBO operator) and the weighted geometric mean weakening buffer operator (TVWGAWBO operator) are pretreated for the time intuitionistic fuzzy sequence. Second, using the time intuitionistic fuzzy set operation rules to determine the niche optimum value; finally, the suitability evaluation model based on the similarity measure of time intuitionistic fuzzy sets and the evaluation process of the method are set up. A new model is provided for the dynamic evaluation method of innovation niche suitability. (6) study the suitability of regional innovation niche in Liaoning province. In order to verify the validity and feasibility of the method, an innovative niche suitability evaluation method constructed in this paper is used to verify the suitability of regional innovation niche in Liaoning Province, and good results have been achieved.
