英文摘要：

Based on the social exchange theory, this paper presents an empirical work conducted on data obtained from staffs of middle and lower class in a state enterprise in Liaoning. This paper intends to explore how the interpersonal trust influenced employee extra-role behavior, and to analyze the mediating effect of the leader-member exchange （LMX） between them. These data are analyzed by validity analysis, correlation analysis and hierarchical regression analysis. This study aims to examine the relationship between organizational trust, LMX and organizational citizenship behavior（OCB） and counterproductive work behavior （CWB）, and verifies that the organizational trust influences OCB and CWB through the LMX. We are also observed that LMX plays a intermediary role between organizational trust and employee extra-role behavior.
