Analysis of the Spatial and Temporal Pattern Evolution of the Opening-up of the Yangtze River Economic Belt:Evidence from 108 Prefecture-level Cities
High-level opening up is an important way to achieve coordinated regional development and Chinese-style modernization.This study constructs an evaluation index system for foreign opening-up based on three dimensions:scale and quality of opening-up,opening-up infrastructure,and opening-up potential.The entropy method,Dagum Gini coefficient and other methods are used to measure and analyze the opening up level of 108 prefecture-level cities in the Yangtze River Economic Belt from 2004 to 2021.The study finds that:(1)The level of opening up of the Yangtze River Economic Belt continues to increase and presents an open pattern of downstream＞midstream＞upstream.The opening up of the upstream region is mainly subject to the degree of openness and open potential,while the midstream region is subject to open infrastructure.Both midstream and upstream areas lag behind downstream areas in all three dimensions,with the gap in opening-up potential further widening.(2)There is a big difference in the overall opening up,but it shows a narrowing trend.The super variable density replaces the inter-regional difference as the main source of the overall difference,and the opening gap between the upstream and downstream and within the upstream region is the most obvious.The spatial dispersion of opening to the outside world continues to increase,and there is a certain polarization phenomenon in the whole,upstream and downstream regions.The downstream cities have formed a spatially concentrated high-level opening-up cluster,while most of the middle and upstream cities have a low level of openness and face challenges in upward mobility,and the siphon effect of the central cities has been weakened.
