珠江-西江经济带“四化”融合时空格局研究

The Study on the Integration of the "Four Modernizations" and Spatiotemporal Pattern in the Pearl River-the Xijiang River Economic Belt

以珠江-西江经济带11个地级中心城市为对象,利用综合评价指标体系和探索性空间数据分析工具,基于不同空间组团及主体功能区背景,评估经济带不同区域"四化"协调度及其时空演进态势。结果显示:珠江-西江经济带"四化"整体协调水平趋于上升,但各组团内部的融合度存在东部优于西部的空间非均衡特征,融合的时空演变呈自东向西梯度转移态势。中心城市作用强度、信息化与传统产业协同力、空间分工水平是导致融合水平差异的主要因素。强化政策引导、推进信息化与传统产业深度融合、优化国土空间功能、发挥比较优势是驱动"四化"协调度整体提升的重要路径。

Based on the background of different spatial groups and the main functional area,this study takes 11 cities of the Pearl River-Xijiang river economic belt as the research object to evaluate the coordination degree of ＂four modernizations＂ and its spatiotemporal evolution by using comprehensive evaluation index system and exploratory spatial data analysis tools.The results show that the overall coordination level of the ＂four modernizations＂ in the Pearl River-Xijiang River economic belt tends to rise,but there is an unbalanced characteristic that the east is better than the west in the degree of integration within each group,the integration of spatiotemporal is shifted from east to west.The strength of the central cities,the synergy competency between informatization and traditional industry and the spatial division of labor are the main factors that lead to the horizontal differentiation.Strengthening policy guidance,promoting the deep integration of informatization and traditional industry,optimizing the function of land and space and playing a comparative advantage are the important ways to drive the overall improvement of the ＂four modernizations＂ coordination.
