This study presents and tests a framework that links leader—member exchange (LMX) with two different forms of employee–organization exchange: organizational social exchange and organizational economic exchange. We propose that these two forms of employee exchange with the organization would be the main mechanisms through which LMX affects employees’ affective commitment and intention to leave. We used structural equation modelling to analyze the data collected from 239 employees in a foreign-invested enterprise in China. Results showed that both organizational social exchange and organizational economic exchange acted as full mediators in the relationships between LMX and the two outcome variables but in different directions. Theoretical and practical implications are discussed.
