Purpose: The purpose of this paper is to examine the impact of green supply chain management on environmental performance (EP), operational performance (OP), and business performance in the context of a developing country, Jordan. In addition, the mediating effects of environmental and OP on the relationship between green supply chain management and business performance are investigated. Design/methodology/approach: The study is based on survey data collected from 215 manufacturing firms from different industries in Jordan. Validity and reliability analyses were carried out using SPSS and Amos. Direct and indirect effects were tested using structural equation modeling. Findings: The results revealed that green supply chain management positively and significantly affects both EP and OP. The results also demonstrated that the total effect of green supply chain management on business performance is positive and significant. The direct effect of green supply chain management on business performance proved to be negative, but insignificant. Thus, the total positive effect of green supply chain management on business performance is indirect and fully goes through EP and OP. Originality/value: This study is one of the first to examine the direct and indirect effects of green supply chain management on business performance, especially in a developing country and the Middle East in particular. Furthermore, this study contributes to the existing body of knowledge by investigating the mediating effects of EP and OP on the green supply chain management and business performance relationship.

Purpose: The purpose of this paper is to examine the effect of transformational leadership on employees’ creativity in the Jordanian banking sector through the mediating effect of perceived organizational support.Design/methodology/approach: The study is based on survey data collected from 369 employees working in Jordanian banks. Validity and reliability analyses were performed, and direct and indirect effects were tested using structural equation modeling.Findings: The results indicate that transformational leadership positively affects some dimensions of employees’ creativity and perceived organizational support. However, perceived organizational support is found to not be significantly related to some dimensions of employees’ creativity. Additionally, the mediating effect of perceived organizational support on the relationship between transformational leadership and some dimensions of employees’ creativity is found to not be significant.Originality/value: This paper is one of the first to examine the relationship between transformational leadership and employees’ creativity through perceived organizational support, especially in an Arab country and in the banking sector.

Purpose: The purpose of this paper is to examine the impact of green supply chain management (GSCM) on environmental performance (EP) and export performance in the context of a developing country, Jordan. In addition, the mediating effect of EP on the relationship between GSCM and export performance is investigated.Design/methodology/approach: The study is based on survey data collected from 221 manufacturing companies in Jordan. The companies were selected from different industry types to ensure diversity. Validity and reliability analyses were performed using SPSS and Amos, and structural equation modeling was used to test the study hypotheses.Findings: The results revealed that GSCM positively and significantly affects both EP and export performance. In addition, the results demonstrated that EP positively and significantly affects export performance. Further, it is also found that EP positively and significantly mediates the relationship between GSCM and export performance.Originality/value: The current study is one of the first to investigate the impact of GSCM on export performance, especially in the context of a developing country. In addition, this study contributes to the existing literature by highlighting the mediating effect of EP on GSCM—export performance relationship. GSCM is an under-investigated area in Jordan. The results are expected to promote GSCM implementation among manufacturing companies in Jordan in order to achieve economic benefits by increasing their exports through improvements in EP.

Purpose: The purpose of this paper is to investigate the effects of knowledge management (KM) on product and process innovations, as well as on operational performance (OP). In addition, the effects of product and process innovations on OP, as well as their mediating effects on the relationship between KM and OP, are also investigated.Design/methodology/approach: A questionnaire-based survey was designed and used to collect data from 207 manufacturing companies operating in the Jordanian capital Amman. To assess construct validity, exploratory and confirmatory factor analyses were conducted. To test research hypotheses, the bootstrap re-sampling method was applied using Hayes’s SPSS multiple-mediator PROCESS macro.Findings: The results indicate that KM has significant positive effects on product and process innovations, and OP. Process innovation was found to have a significant positive effect on OP, while product innovation was not. Furthermore, only process innovation was found to significantly mediate the KM-OP relationship.Practical implications: The findings of this study provide useful insights about the role of KM in facilitating and enhancing product and process innovations, as well as OP in the surveyed manufacturing companies. An important implication concerns the roles of product and process innovations. Manufacturing companies seeking improvements in their OP are recommended to focus on process innovation rather than product innovation. While product innovation may affect other aspects of performance, such as market and financial ones, it was not found to significantly affect OP. Process innovation can also leverage KM’s contribution to manufacturing companies’ OP.Originality/value: This is a pioneering study in that it developed an integrated model that depicts the interrelationships among KM, product innovation and process innovation and OP, in a developing country context.
