Research On Technology Evolution Based On Relevance Relations

As one of the important driving forces of economic and social development,accurately grasping the development status and trend of technology is the key to seize the opportunity in complex environment.Recently,with the rapid development of technology,technology has become more complex and diversified,and the uncertainty in the process of technology development has intensified.Analyzing the evolution process of specific technology field,sorting out its development context,objectively grasping the inherent law of technology development,and defining the key nodes in the process of technology development can provide reliable help for scientific researchers to grasp the frontier of technology development and solve the difficulties in technology development,and also play an important role in assisting national technology strategy deployment and enterprise technology scheme selection.Technology usually does not exist in isolation,but interdependent,interrelated and interdependent with other technologies in various forms.The refinement of technology division and the extension of industry chain make the degree of technology connection deepen continuously,and the forms of technology connection become more diverse.The interrelation of technology makes the formation and evolution of technology system or technology field show certain synergy,and also becomes an important factor to promote technological progress and industrial development.In a specific technology field,what kinds of relationships among technologies and how different technologies interact with each other are worthy of in-depth analysis.In this paper,the evolution process of specific technology fields is analyzed from the perspective of technology correlation.Firstly,the relationship between technologies is divided into deep and fine-grained categories from various perspectives,and the classification framework of technology relationship is constructed.On this basis,the form of technology association involved in the process of technology evolution is selected.Taking the field of image recognition technology as an example,the technology association relations in this field are annotated,and then the fine-grained technology evolution analysis is achieved.
