This study aims to clarify the relationships among total interdependence, dependence asymmetry, social interaction, and buyer firms' manufacturing technology capability. A conceptual model is established and a questionnaire is designed by adapting suitable measurements from literature. Data are collected from small-medium enterprises in manufacturing industry in Taiwan. Analysis results show that higher total interdependence between buyer and supplier leads to higher level of social interaction. Higher buyer-supplier dependence asymmetry will decrease the interaction between the buyer and supplier. The results are investigated in detail and managerial implications are then provided.
