“比较”视角下的长江经济带近期发展时空格局分析

Analysis of Spatial-Temporal Patterns of the Recent Development of the Yangtze River Economic Belt from Comparative Perspective

为探究长江经济带上升为国家重点战略以来的发展现状和时空演化格局,论文采用数理统计和空间分析方法,围绕人口、土地、经济、交通、生态等5个关键维度,识别长江经济带发展的综合水平(与全国比较)及其内部的区域差异,把握其时空变化规律。研究发现:(1)在国家战略驱动下,长江经济带的人口和土地城镇化发展增长趋势明显,高于全国平均水平;(2)经济带内部区域发展表现出强烈的空间不均衡性,呈现“从西到东递增”和“两端高、中部低”的空间特征;(3)全域协同发展水平有所提高,各省市间的差距在时序上呈不断缩减态势。建议未来在秉持“生态优先、绿色发展”理念的基础上,重点关注中游地区的发展建设,进一步发挥黄金水道的作用,促进区域协同发展。

Examining the impact of China’s latest national strategies on the development of the Yangtze River Economic Belt(YREB)is crucial.To address this,we conduct a comparative study from macro,meso,and micro perspectives,incorporating statistics,spatial analysis,and comparative analysis.Our study focuses on fi ve dimensions:population,land,economy,transportation,and ecology.In particular,we analyze the spatial patterns of YREB’s development by comparing the upstream,midstream,and downstream areas and their respective provinces and cities.Our fi ndings reveal the following:(1)Since 2014,YREB has seen substantial growth in terms of land use and population,and its strategic importance within China has increased;(2)There are notable disparities across YREB regions,characterized by spatial patterns such as“low-west and high-east”or“high at both ends and low in the middle”;(3)The level of coordinated development in the region has improved,and the gap between provinces and cities has diminished.In light of the principle of“ecology priority,green development”,we recommend that the government improve the effi ciency of the Yangtze River and prioritize central China as the focus of future development to enhance regional synergy.
