Action path	Relational structure	Meaning of path
Emotional Cognition→Knowledge Anxiety	causality	Emotional Cognition is the main factor of researchers' Knowledge Anxiety behaviour, and the negative Emotional Cognition induces them to produce Knowledge Anxiety behaviour.
Academic Characteristics→ Emotional Cognition	causality	Academic Characteristics can affect users' Emotional Cognition and induce researchers' Knowledge Anxiety behaviour.
Outer Environment→ Emotional Cognition	causality	External situation will affect the user's Emotional Cognition, and then induce the researchers to produce Knowledge Anxiety behaviour.
Cognitive Environment→ Emotional Cognition	causality	Cognitive Environment will affect the user's Emotional Cognition, and then induce the researchers to produce Knowledge Anxiety behaviour.
Ability Characteristics→Academic Characteristics→ Emotional Cognition	adjusting relationship	Ability Characteristics of researchers affect the processing effect of knowledge attributes, and then promote the different Emotional Cognition of researchers.
Ability Characteristics→Outer Environment→ Emotional Cognition	adjusting relationship	The Ability Characteristics of researchers affect the adaptation to the Outer Environment, and then promote the different Emotional Cognition of researchers.
Ability Characteristics→ Cognitive Environment→ Emotional Cognition	adjusting relationship	Ability Characteristics of researchers affect the adaptation to the constructed situation, and then promote the different Emotional Cognition of researchers.
