PurposeGreen product innovation is a global industrial concern. This research examines the possible impact of green product innovation on firms' competitive advantage in industrial enterprises operating in qualified industrial zones (QIZs).Design/methodology/approachThis research follows a descriptive analytical methodology, testing two hypotheses formulated based on the reviewed literature among chemical industrial plants of the three Jordanian QIZs (Amman, Zarqa and Irbid) in Jordan. Following a preliminary scoping study of all 219 Jordanian chemical manufacturers, a quantitative five-point Likert scale questionnaire was administered to firms applying green product activities.FindingsIn total, 20 firms were found to be utilizing green product innovation, representing only 9.13% of the overall population. The hypothesis testing results indicated that green product innovation has a statistically significant positive impact on competitive advantage. The results also showed that the factor “firm resources” has a statistically significant positive moderation effect on the relationship between green product innovation and competitive advantage.Research limitations/implicationsThe vast majority of Jordanian chemical manufacturers were not implementing green innovation or practices; further study is needed to identify barriers. Findings are limited to managers of chemical industrial plants in Jordan, excluding the demand side (e.g. plant customers who purchase final products), which leaves a different research angle to be explored.Originality/valueThis is a pioneering study of green product innovation implications for firm competitive advantage in manufacturing enterprises, especially in QIZs of Jordan (which offer tax exemptions to foreign and local investors and sell products to regional and international markets).

The purpose of this quantitative research was to measure customer satisfaction with bank tellers and bank teller leadership attributes and to determine the relationships between the two and the effect of gender on the ratings. Data were collected at three bank branches in West Amman-Jordan with 126 bank customers. The results revealed statistically significant differences in the ratings of the leadership attributes: Ethics had highest ratings while innovation had the lowest ratings. There were significantly different gender ratings in two leadership attributes such that women's ratings were higher than the men's in bank knowledge and communication leadership attributes. Also, men and women differed significantly on satisfaction; women were more satisfied than men. Moreover, results revealed that satisfaction correlated directly, strongly, and significantly with all five leadership attributes. Additionally, results showed that bank knowledge, innovation, and gender all made unique and statistically significant contributions to predicting satisfaction with bank tellers.
