Abstract

This study aims to measure the coupling coordination degree and identity main influencing factors in Hebei province. This study used the coupling coordination model to calculate the comprehensive index, coupling degree and coupling coordination degree and the grey relational model for main influencing factors of the EES system in Hebei province from 2010 to 2018. The results show that: (1) The ecological index and economic index of Hebei province show a u-shaped curve, the social index is on the rise, and the development level of each system is in a low level of fluctuation. (2) The coupling level of the three subsystems is relatively high, but the coupling coordination is still a low level of coordinated development. (3) The order of the coupling coordination degree affected by the index of the system layer is social > ecological > economy, and there is a strong correlation among them.
