Research on the Coordinated Coordination Development of Technological Innovation,Economic Growth,and Ecological Environment in the Yangtze River Economic Belt
Technological Innovation,economic growth,and ecological environment coupled coordination is an inevitable requirement for achieving high-quality economic development in the Yangtze River Eco-nomic Belt.Based on panel data from 11 provinces and cities in the Yangtze River Economic Belt from 2000 to 2022,this study constructs a subsystem evaluation system for technological innovation,eco-nomic growth,and ecological environment.Utilizing entropy method and coupling coordination degree model,the spatial and temporal changes of technological innovation,economic growth,and ecological environment coupled coordination in the Yangtze River Economic Belt and its sub-regions are explored.The research findings are as follows:①From 2000 to 2022,the development levels of technological in-novation,economic growth,and ecological environment subsystems in the Yangtze River Economic Belt and its three major sub-regions have shown an overall upward trend.The development indices of techno-logical innovation and economic growth are significantly higher than that of the ecological environment.②Over the past 23 years,the coupling coordination degrees of technological innovation,economic growth,and ecological environment in the Yangtze River Economic Belt and its three major sub-regions have exhibited a clear increasing trend,transitioning from a state of imbalance to coordination.The coor-dination stage in the provinces and cities of the upper and middle reaches of the Yangtze River lags be-hind that of the lower reaches.In terms of spatial evolution,the coupling coordination degree in the Yangtze River Economic Belt shows a decreasing trend from east to west.By 2022,all subsystems in the 11 provinces and cities of the Yangtze River Economic Belt have reached a well-coordinated stage.Further efforts should be made to strengthen the synergistic development of technological innovation,e-conomic growth,and ecological environment in the Yangtze River Economic Belt,and leverage the radi-ating effects of downstream provinces and cities on those in the upper and middle reaches.
