In this paper, we investigate the multiple attribute decision making with hesitant fuzzy information. Motivated by the ideal of dependent aggregation, in this paper, we develop some dependent hesitant fuzzy aggregation operators: the dependent hesitant fuzzy ordered weighted averaging (DHFOWA) operator and the dependent hesitant fuzzy ordered weighted geometric (DHFOWG) operator, in which the associated weights only depend on the aggregated hesitant fuzzy arguments and can relieve the influence of unfair hesitant fuzzy arguments on the aggregated results by assigning low weights to those "false" and "biased" ones and then apply them to develop some approaches for multiple attribute group decision making with hesitant fuzzy information. Finally, an illustrative example for supplier selection is given to verify the developed approach and to demonstrate its practicality and effectiveness.Keywords: Multiple attribute decision making, hesitant fuzzy information, dependent hesitant fuzzy ordered weighted averaging (DHFOWA) operator, dependent hesitant fuzzy ordered weighted geometric (DHFOWG) operator, supplier selection

The relationship between economic growth and environmental quality is generally considered as linear, N-shaped or inverse-U-shaped curve. However, due to the effects of economic structure on economic growth and pollutant emission, this relationship may not be suitable in China. In this study, multivariate regression modeling was performed to identify relationships among pollutant emission, economic structure and economic growth in China. Estimates obtained from integrated multivariate regression results reveal that local provincial economic growth and pollutant emission demonstrate an inverse-N-shaped relationship that is different from that under the Environmental Kuznets Curve (EKC) hypothesis. Further empirical results also indicate that particularly in China; pollutant emission has a negative effect on economic structure and economic growth; pollutant emission can reduce the positive contribution of economic structure to economic growth; and enforcement of emission reduction policies could stifle economic transformation and maintain sustainable economic growth.
