Coupling Coordination and Spatial Evolution of Sustainable Tourism-Innovation-Environment System: Evidence in China

Abstract

Coupling tourism development (TD), scientific and technological innovation (ST), and ecological environment (EE) is crucial to regional sustainable development, and it is necessary to explore the spatial and temporal characteristics. The study constructs a coordinated development evaluation index system for the three subsystems. And the spatiotemporal characteristics of the coupling coordination between TD, ST, and EE were revealed by applying the entropy method, coupling coordination model and based on the panel data of 30 regions in China from 2005 to 2020. The results show that: (1) the comprehensive development index and coupling coordination degree show an increasing trend, focusing on the stages of endangered and mild imbalance recession;(2) Most regions are in a state of high coupling and low coordination, mainly concentrated in tourism lagging or science and technology lagging; (3) the coupling coordination shows a spatial pattern as the moderate imbalance in the northwest and the relative balance in the southeast, with a vast regional disparities and clustering characteristics; and (4) the gray prediction model shows that the coupling coordination degree will continue the upward trend in the future. In a nutshell, this research presents a novel framework and results that can be used as an evaluation index and policy insights for coupling TD, ST, and EE.
