Abstract
In the context of high-quality development, the development paradigm of integrating scientific and technological innovation, talent agglomeration, and new-type urbanization has become a key issue in regional development. Taking the Yangtze River Economic Belt as an example, this paper analyzes the interaction mechanism of the three systems and constructs an evaluation index system from the perspective of regional high-quality development. This paper combined entropy weight TOPSIS, coupling coordination degree model, and Gini coefficient to explore the spatial and temporal characteristics and regional differences of system coupling coordination. The evolution trend of the coupling coordination type is predicted by the Markov chain model. The research shows that: (1) The development index of the three major systems in the Yangtze River Economic Belt is on the rise, and the coupling coordination degree is in the running-in stage as a whole. The resistance restricting the coupling coordination degree is mainly the lag of scientific and technological innovation in the upstream, and the lag of talent gathering in the middle and downstream. ( 2) The coupling coordination degree of the three systems has obvious spatial agglomeration characteristics, showing a high level in the lower reaches of the Yangtze River, and a low level in the middle and upper reaches of the Yangtze River. (3) The gap of the coupling coordination degree of the three systems in the whole Yangtze River Economic Belt is gradually narrowing, and the large development gap among different regions is still the main cause of the Gini coefficient of the Yangtze River Economic Belt. (4) There is a location difference in the probability of coupling coordination level transfer, and the upper and middle reaches of the Yangtze River will still be in the antagonistic or running-in stage in the next stage, while the lower reaches of the Yangtze River will be in the coordination stage. The research conclusions provide scientific references for the high-quality development of the Yangtze River Economic Belt.
