Research on Technology Opportunity Identification of Small and Medium-sized Vaccine Enterprises Based on Patent Analysis

Objective To propose a method for identifying cooperation partners and technology opportunities based on technological similarity and technological capability analysis at the critical moment for the survival of small and medium-sized vaccine companies.This method can provide a direction for small and medium-sized enterprises that lack human and financial resources to make full use of its existing technologies.Methods Data analysis was carried out based on patent data.First,through cosine similarity and patent index evaluation,companies with high technological similarity and strong technological capabilities were selected as the target of cooperation.Then evaluation index system of technological development potential was built from three dimensions:technological competitiveness,technological creativity,and potential for industrialization.AHP-CRITIC method was used to determine the comprehensive development potential of each technology.Finally,technology opportunities based on K-means and text mining were identified.Results and Conclusion This method can help small and medium vaccine companies in China to identify technological opportunities and provide directions for product development.

The Evolution of Innovation Mode for Technology-Based Small and Medium-Sized Enterprises under the Synergy of Opportunity Identification and Ambidextrous Strategic Combination

Taking Company M as the research object,this studyadopts a case study methodtoexploretheevolutionofenterprise competitive advantage differentiation matching and resource-focused action in the iterative innovation process under the synergy of opportunity identification and ambidextrous strategic combination.This study reveals the formation mechanism and path of iterative innovation in enterprises,finding that opportunity identification is a dynamic and complex process with significant variations.Enterprises can creativeyly utilize the synergbyetween ambidextrous strategic combinations based on the identified opportunities to stimulate differentiated allocation of competitive advantage modules based on resource heterogeneity and incomplete factor-mobility,and to achieve strategic flexibility.The adaptive interaction between opportunity identification and ambidextrous strategic combination drives the staged evolution of resource-focused action,including resource bricolage,arrangement,and orchestration,thereby realizing the iterative innovation process of"technology exploration based development model-market expansion-based development model-collaborative innovation-based development model."

Identification of refactoring opportunities for source code based on class association relationships

In order to deal with the complex association relationships between classes in an object-oriented software system,a novel approach for identifying refactoring opportunities is proposed.The approach can be used to detect complex and duplicated many-to-many association relationships in source code,and to provide guidance for further refactoring.In the approach,source code is first transformed to an abstract syntax tree from which all data members of each class are extracted,then each class is characterized in connection with a set of association classes saving its data members.Next,classes in common associations are obtained by comparing different association classes sets in integrated analysis.Finally,on condition of pre-defined thresholds,all class sets in candidate for refactoring and their common association classes are saved and exported.This approach is tested on 4 projects.The results show that the precision is over 96%when the threshold is 3,and 100%when the threshold is 4.Meanwhile,this approach has good execution efficiency as the execution time taken for a project with more than 500 classes is less than 4 s,which also indicates that it can be applied to projects of different scales to identify their refactoring opportunities effectively.
