Based on the grounded theory, 46 interviewees were interviewed through personal in-depth interviews and focus group interviews, and the interview data was analyzed in three stages to construct an integrated analysis model of social media users' anxiety. User anxiety is affected by emotional cognition and experience, platform environment and operation quality. Under the effect of user personality traits, it is characterized by state anxiety and general anxiety. Anxiety further leads to the user's avoidance behavior. The intensity and behavior of the avoidance behavior are regulated by the characteristics of the individual's ability, and positive avoidance behavior or passive avoidance behavior occurs. Active avoidance behavior will have a feedback effect on the Weibo platform environment and the quality of Weibo operations when users use it personally.

[Purpose/significance] The introduction of SOR theory in the field of library and Information Science (LIS) in China has achieved phased achievements. When it refers to SOR theory, related researches have discussed the con? notation and basic framework of it. In order to provide further reference for the normative application of SOR theory in LIS research, this paper attempts to systematically review the current domestic literature on the application of SOR the? ory in LIS research. [Method/process] The study analyzes the traceability, three-dimensional characteristics, applica? tion topics and application process of SOR theory in LIS field in China, aiming to clarify the applicability, advantages and limitations of SOR theory. [Result/conclusion] The results show that the majority of literature mainly focuses on the topic of information behavior, and the interpretation of factors and relations of stimulus and organism dimension can be divided into "direct interpretation" and "cooperative interpretation with other theories or models". In terms of theo? retical coordination, the stimulus dimension is mainly extended by the theories about "the behavior and motivations of users", while the organism dimension is combined with the theories about "the cognition and emotion of users", and the response dimension is developed from two perspectives of "approach- avoidance". Application topics include virtual knowledge community, social and business platform, mobile government platform and online platform of university li? brary, etc. And there are some differences in the core variables of each topic. Research design has a distinct characteris? tic of "method- process", which can be divided into qualitative, quantitative and mixed processes. Based on the re? search review, this paper proposes some suggestions for the future application of SOR theory in LIS field, such as using the theory critically, focusing on the antecedents of the stimulus dimension, expanding research of the organism and re? sponse dimension, and improving dynamic measures and data objectivity.

 [Purpose/significance] The purpose of this paper is to explore the cause and mechanism of social media herd information sharing behavior, and to provide a theoretical reference for the guidance of user information behavior, the supervision of public opinion information and the optimization of network information dissemination mechanism. [Method/process] This paper introduces the variables of self-efficacy in information screening, subjective norms, and information source credibility from the aspects of actors, situations or relationships and objective stimuli, and con? structs a theoretical model by combing the relationship between variables. Then, 262 valid data were collected by ques? tionnaire, and the partial least squares structural equation model (PLS-SEM) was used for data analysis and model veri? fication. [Result/conclusion] Self-efficacy in information screening, subjective norms and information source credibili? ty all have a significant positive impact on herd information sharing behavior of social media users, and in which the im? pact of subjective norms is the greatest. In addition, self-efficacy in information screening can negatively regulate the impact of subjective norms on herd information sharing behavior of social media, but cannot adjust the impact of infor? mation source credibility on herd information sharing behavior of social media. This study reveals the cause and mecha? nism for herd information sharing behavior of social media users, provides a reference for people to understand users' herd information behavior, provides a reasonable explanation for the phenomenon of "screen brushing" in social media, provides an example and scene for the application of triple degree attribution theory, and also provides strategic enlight? enment for service optimization and policy formulation of relevant parties, which has certain theoretical and practical significance.

[Purpose/significance] Based on the SOR(Stimulus-Organism-Response) model, this study explored the ef? fect of social support on user engagement based on the mediating role of emotion in online health communities.[Meth? od/process] Taking social support as the "Stimulus" (S) factor and emotion as the " Organism "(O) factor, this paper studied the mechanism of users' " Response" (R).We obtained 465 337 posts by 244 users from an online health com? munity as sample data. The hierarchical regression analysis is used to test the conceptual model. [Result/conclusion] The results show that information support, emotional support and social support provided by the online health communi? ty had a positive impact on the users' engagement behavior. In addition, user emotion has a significant partial mediating effect on the relationship between social support and user engagement behavior, and this mediating effect is moderated by user gender, that is, the mediating effect of emotion has a greater impact on male users.

[Purpose/significance] In the new technological environment, clarifying the factors that influence the will ?
ingness of digital youth to pay for digital reading and putting forward suggestions for the improvement of digital reading
services have great significance for expanding knowledge in the field of digital reading payment and optimizing the de ?
velopment of the digital reading industry. [Method/process] Based on the user's perceived value theory and technolo?
gy acceptance model, combined with the characteristics of digital reading, a structural equation model of the influenc?
ing factors of digital youth's willingness to pay for digital reading is constructed. [Result/conclusion] The research re?
sults show that the willingness to pay in the digital reading process of digital youth is mainly affected by perceived value
and perceived ease of use. Among them, the perceived value has the greatest influence on the willingness to pay. In ad?
dition, perceived value plays a significant intermediary effect on perceived gains and perceived losses. Perceived use?
fulness, perceived risk, and perceived cost need to be transformed into perceived value to affect the payment willing ?
ness of digital youth. Only perceived ease of use can directly affect the willingness to pay.

Abstract：[Purpose/significance] Exploring the factors of using the time limit dynamic setting launched by WeChatMoments, and provide theoretical and practical suggestions for researchers and practitioners regarding settings on social media platforms, under the context of“time collapse”in social media. [Method/process] We conducted semistructuredinterviews to collect data from 30 respondents, by open coding, axial coding and selective coding, based ongrounded theory. Then, we summarized and analyzed the data to explore what factors influencing individuals’uses ofthe time limit dynamic setting. [Result/conclusion] The results show that historical information factors (e.g., inforamtion sensitivity) on social media impact use motivations (e.g., social motivation), and in turn influence the use of timelimit dynamic setting. Meanwhile, use motivations would affect the use of time limit dynamic setting through benefits ofusing settings (e.g., impression management) and costs of using settings (e.g., selfpresentation barrier). Additionaly, individual factors and situational factors could moderate relevant relationships which we mentioned above.
