At present, evaluation methods of innovation niche-fitness have been widely used in many fields, its value is gradually accepted by society, but it is still in its infancy in theoretical research, few research results, there are many theoretical issues need to improve. In this paper, theoretical exploration of niche-fitness evaluation methods with innovation ecosystem theory:This paper puts forward innovative ecological factors assignment method on vague sets, and which emphasizes ecological characteristics. And puts forward evaluation methods of innovation niche-fitness based on vague sets and interval valued vague sets, explores static method on vague sets distance. And puts forward evaluation methods of innovation niche-fitness based on time valued vague sets, explores dynamic method on vague sets similarity degree. And applies evaluation methods of innovation niche-fitness constructed to solve real-world innovation ecosystem evaluation.The research content is as follows:(1) Describe the research background and significance, research status, research purposes, methods, content and logical framework and innovation points.(2) Comb innovation ecosystem theory, niche-fitness evaluation theory and comprehensive evaluation on vague sets, building a theoretical basis for this research.(3) Research innovative ecological factors assignment method on vague sets. Firstly, put forward the Conception of extreme value type (large or small) and limited type innovative ecological factors, and data conversion method. Secondly, put forward innovative ecological factors assignment methods basing on niche model, and which possess ecological characteristics, and which are geometric-series model and broken stick model. Finally, put forward the method of assigning weights on extreme value type innovative ecological factors on truth-membership grade point and false-membership grade point, and put forward the method of assigning weights on limited value type innovative ecological factors on hesitancy grade point.(4) Research evaluation methods of innovation niche-fitness based on vague sets. Firstly, put forward the definition and measurement methods of vague hyper volume niche; secondly, construct evaluation methods of innovation niche-fitness on vague sets, including ecological factor weighting method on ?-OWA, niche optimum value determination method, evaluation models of innovation niche-fitness on vague sets distance, and evaluation process. Finally, construct evaluation methods of innovation niche-fitness on interval valued vague sets, including niche optimum value determination method and evaluation models of innovation niche-fitness on vague sets distance.(5) Research dynamic evaluation methods of innovation niche-fitness based on time value vague sets. Firstly, reference grey system theory put forward two new operators (TVWA WBO and TVWGA WBO) basing on weakening buffer operator (WBO) and extended operators to pretreated time valued vague sets data sequence; secondly, determine niche optimum value on vague sets operational rules; Finally, construct evaluation models of innovation niche-fitness on vague sets similarity degree, and put forward evaluation process.(6) Research on regional innovation niche-fitness evaluation problem in Liaoning Province. The effectiveness and availability of evaluation model constructed have been proved by the practical application in Liaoning Province regional innovation niche-fitness evaluation problem. As expected, it really outputs desirable results.
