The popularity of SNS-providing web sites has increased continuously and its kinds of service, such as personal connection management, commerce and education, have been diversified. The connection to SNS can be possible not only with conventional PC but also with a variety of mobile devices. Via these tools, SNS users can share lots of information and therefore the service sphere of SNS expands continuously.
As a means of advertising, SNS has not only economical values but also considerable social ripple effects. SNS can be used as a political and social communication tool to exchange and share views of specific issues with other users. Sometimes, such activities can develop into offline activities and therefore have no small influence upon society. In contrast to the values of SNS, which receives increased attention for the present, studies on its characteristics and users have not been carried out sufficiently. Since there have only been partial studies on SNS, such as on blog, mini-homepage and microbloging, it is necessary to carry out systematic studies on SNS comprehensively. SNS is a web-based application, but from the aspect of its application area and service, it has more attributes than a mere information technology, as a business site of forming mutual relations, providing and sharing information and carrying out economical activities. Therefore, in order to measure the quality of complex structure of SNS and predict and explain its user behavior, it is necessary to approach it comprehensively from the aspect of information system and user cognition.
As for domestic providers of SNS, Naver and Daum expand their service area to SNS service on the basis of the existing Internet-related services(portal, mail, UCC, game and so on), whereas Cyworld expands its service area to the Internet-related various services on the basis of SNS service. Now, Naver, Daum and Nate are carrying out a variety of businesses, such as portal, mail, cafe(club), UCC, game and microbloging. The current issue is a microbloging-related service, but the maintenance and expansion of business entities' conventional business are consistently performed. Therefore, it is very important to examine the difference of content and function of SNS service and user's requirements. It is meaningful to analyze user's needs for SNS and influential factors for its services. The most necessary examination on SNS for the present seems to be systematic understanding of its services and use characteristics. From the aspect of business entities, it is necessary to understand the planning and operation of SNS and comprehensively analyze the cognition and behavior of users.
In this study, in order to examine the characteristic of SNS, the investigator used the quality factor of Information System Success Model presented by DeLone & McLene (2003). SNS is a web-based application and an information technology-based service. In this vein, in order to analyze the characteristic of SNS, therefore, the investigator redefined the quality factor of DeLone & McLene according to the theme of this study and added social influential factor and personal emotion factor, thus presenting the quality factor of SNS. As for the social influential factor and personal emotion factor, the investigator examined preceding studies and drew out additional factors.
In the area of information system, researchers have traditionally carried out active studies on customer's continuous purchase, customer participation and customer maintenance, but studies on web-sites, especially on customer's continuous use of SNS service, have not been actively carried out. Therefore, it is not yet clear the relation and influence of use satisfaction and cognition level―important precedential variables of continuous use intention―upon SNS environment for the present. In this vein, the investigator tried to apply the results of preceding studies on traditional user satisfaction and sustainable use to SNS environment, thus presenting influential factors upon user satisfaction and sustainable use.
In order to examine the influence of quality factors upon user recognition level, the investigator extendedly applied the expected confirmation model(ECM). ECM only takes the usability, recognized as a post-use belief, into account, but lots of current information systems emphasize the usability of information system as well as the amusement aspect and use convenience aspect. In order to reflect these phenomena, the investigator presented an extended ECM by adding recognized pleasure and use convenience to the existing ECM. By doing so, the investigator tried to draw out important influential factors upon user's expected level and then present a guideline for business entities to use in planning and developing SNS-related services.
Study findings from the aspect of theories are as follows:
First, via systematic examination on preceding studies, the investigator theoretically presented influential factors upon user satisfaction and sustainable use for SNS user's ECM. In addition, via empirical analysis, the investigator presented verified variables and measurement items, and via structural equation model the investigator verified the causal relations among SNS quality factor, user recognition factor and dependent variables(user satisfaction and sustainable use).
Second, the investigator developed measurement items of which SNS quality factor, presented in SNS user ECM, user recognition factor, definition for dependent variables, reliability and validity were ensured, thus creating the basis of empirical studies on this field in the future.
Third, out of social quality and personal emotion quality, two inherent qualities of SNS, personal emotion quality had more significant influence upon user satisfaction and sustainable use in accordance with SNS user's expected confirmation. System quality, an existing quality factor, had more significant influence than any other quality factors. As for the service quality factor, since a 65.7% of Internet users(as of 2010) use SNS since SNS was domestically introduced, users have sufficient knowledge on the use of SNS and therefore do not recognize its service quality as the precedential factor of user satisfaction and sustainable use.
Fourth, since the investigator carried out this study by drawing out not only personal aspect variables which were emphasized in SNS, but also social quality factors (subjective norm, social identity, image and altruism) and emotional quality factors (interaction, immersion, anxiety and self-efficacy) and then applying them to this study, thus making this study an empirical study which taking more broad and various variables into account, this study can provide help to the design of SNS user ECM-related study model in the future.
Study findings from the aspect of practical business are as follows:
First, by verifying the relationship among SNS quality factor, user recognition factor and dependent variables and presenting measurement items of which definition, reliability and validity were ensured for every variable, the investigator created the basis of empirical studies on this area. In addition, since the investigator found out user expectation and cognition, SNS providers can use them as strategic tools for their marketing and establishment of improvement strategy in the future.
Second, such a study finding that out of quality factors which having influence upon the user satisfaction and sustainable use intention of SNS user ECM, emotional quality and systemic quality had positive influence seemingly implies the fact that personal emotion factor has an important function in user's SNS use. In addition, also important is systemic consideration to provide SNS smoothly. Therefore, SNS-related business entities must consider these emotional quality and systematic quality in their providing SNS.
Third, SNS providers must grope after strategies to stimulate user emotion and then provide it to users. In this study, among SNS quality factors, emotional quality and systemic quality were verified as most significant influential factors. This finding seemingly confirms the fact that the greatest motive of SNS use is the formation of mutual relations. This finding can be explained like that if SNS users find out pleasure in communicating with other SNS users by making something special with SNS and attracting people to it or forming one's own images, they will be satisfied and have the intention of sustainable use. In order to improve user satisfaction and induce sustainable use, therefore, SNS providers must concentrate their efforts on groping after a strategy to stimulate user's emotion.
