Drawing on the resource dependence theory, the stakeholder perspective and environmental management capabilities, this study examined the relationship between the heterogeneity of customer pressures and the varying levels of environmental policies in China. Data on 1215 Chinese manufacturing firms were analyzed to demonstrate that environmental pressures emanating from different types of customer have different impacts on firm environmental conduct and that the pressures from multinational consumers have a stronger effect on local Chinese suppliers' propensity to reduce product environmental risks than those from local consumers.
