Exploring the relationship between leadership, operational practices, institutional pressures and environmental performance: A framework for green supply chain

The aim of the paper is to test the impacts of supplier relationship management (SRM) and total quality management (TQM) on environmental performance under the influence of leadership and the moderation effect of institutional pressures (IP). The study investigates these effects using a pretested structured questionnaire. Data was collected using a split survey method using a modified version of Dillman's (2007) total design method with 187 and 174 complete and usable responses for the respective parts. We performed non-response bias before checking assumptions such as constant variance and normality. We further checked reliability and construct validity using confirmatory factor analysis and hierarchical regression analyses for hypothesis testing. We find that constructs and indicators of our theoretical framework meet the criteria, and find them to be a good fit based on confirmatory factor analysis and fit indices output. The hierarchical regression analyses outputs suggest that all our hypotheses are supported, which further supports the extant literature. Our present study is unique in terms of scope and contribution to SCM and OM theory and practice. The study has tested empirically the research calls of various researchers and extended them to green supply chain networks. Our findings support institutional theory. (C) 2014 Elsevier B.V.
