Organizational change is a prerequisite for companies to survive in this competitive global market. The study paid attention to the psychology of the members and the readiness for change that can lead to positive attitudes and beliefs or intentions for change, and to demonstrate whether there is a significant impact by dividing networking behavior into internal and external factors that influence this. In addition, it attempted to clarify the structure in which the knowledge sharing process occurs due to networking activities, and to verify the mediating effect of knowledge sharing. First, only external behavior among networking behaviors of corporate members had significant effect on organizational change readiness. Knowledge sharing has a significant effect on change readiness. Since knowledge sharing is based on trust, social capital is formed, which is a phenomenon that occurs in an environment with low anxiety. Third, networking behavior affects readiness for change through knowledge sharing. This is because networking behavior is largely based on communication, so there is an essential process in which knowledge is exchanged with each other. Finding ot the study implicates that the success in corporate change attempts was found from the perspective of members-led rather than corporate-led, and focused on individual psychological characteristics to uncover the effects.
