Drawing upon relational exchange theory, institutional theory, organizational culture and IS theories, we derive a model to study factors affecting firms’ electronic supply chain management adoption. In particular, we examine the effect of trust, normative, mimetic and coercive pressures on eSCM adoption. Also, we assess the moderating role played by organizational culture in this effect. The research model is tested by data collected with executive MBA students enrolled with a large university in China. Managerial implications and theoretical contribution of this study are discussed.
