Effect of Sustainable Supply Chain Management on Procurement Environmental Performance: A Perspective on Resource Dependence Theory

To reduce medical waste, attention must be paid to the environmental friendliness of products during procurement. Thus, environmental awareness among hospital procurement personnel is crucial. Sustainable development, which effectively utilizes limited external resources, is the common goal of hospitals and suppliers. This study aims to establish a research framework that combines the theories of resource dependence and environmental relationship quality, incorporating environmental factors, subjective environmental norms, and perceived environmental values. Whether the environmental awareness of hospital procurement personnel is related to the quality of supplier relationships was investigated using a questionnaire survey method with hospital procurement personnel as the subjects. A total of 443 valid questionnaires were collected, and structural equation modeling was used to verify the hypotheses. The results show that (1) substitutability and uncertainty have a positive and significant effect on environmental relationship quality; (2) environmental subjective norms have a positive and significant effect on environmental relationship quality; (3) importance and perceived environmental value have a positive and significant effect on environmental commitment; (4) environmental relationship quality has a positive and significant effect on environmental performance. These results provide a reference for the promotion of relevant policies, education, and training in medical institutions.
