Abstract: In order to get a clear picture about the effect of workplace loneliness on the interpersonal deviance of account- ants in the manufacturing industry, by use of the attribution deviation theory and the Social bonding theory, 249 accountants from the manufacturing industry were taken as the research subjects adopting the Workplace Loneliness Scale, Turnover Inten- tion Scale and Interpersonal Deviance Scale. It is found that workplace loneliness, turnover intention and interpersonal deviance are positively correlated to each other; the workplace loneliness can negatively predict the interpersonal deviance; the turnover intention plays partially an intermediate role in the effect of workplace loneliness upon the interpersonal deviance with the medi- ating effect rate of40. 62%.
