基于修正引力模型的“一带一路”中国段省区空间经济联系分析

Economic Links Analysis of the China’s Provinces Along the Belt and Road Based on Modified Gravity Model

区域经济联系对各区域的经济发展产生着重要的影响,研究“一带一路”中国段省区经济联系强度是国家建设“一带一路”省级宏观经济调控的必要方式。文章从定性和定量的角度,基于修正的引力模型,揭示“一带一路”中国段省区经济联系强度“点-线-面”三维度特征。研究结果表明:(1)省区间中心性指数差异明显,在区域分布上具有明显的梯度性;(2)“一带一路”倡议的提出有效提升了中国段大部分省区的经济实力,中心性指数有明显上升趋势;(3)省区间发展不平衡的现状仍较为突出,两个核心区的带动辐射能力差异大,且核心区的经济辐射带动作用都需要改善与提升。

Regional economic links have an important impact on the economic development of each region.It is necessary to ana⁃lyze the economic links strength of China’s provinces along the Belt and Road for the national construction of provincial macroeco⁃nomic regulation and control.Based on the modified gravity model,this paper reveals the three-dimensional characteristics of the economic connection strength of the provinces in China along the Belt and Road from qualitative and quantitative perspectives.The results show that:(1)the centrality index has obvious difference between provinces and regions,and the regional distribution has obvious Gradient property;(2)the“One Belt And One Road Initiative”has effectively improved the economic strength of most prov⁃inces and regions in China,and the centrality index shows an obvious upward trend;(3)the imbalance of development between provinces and regions is still prominent.The driving radiation capacity of the two core regions is greatly different,and the driving ef⁃fect of the economic radiation of the two core regions needs to be improved and enhanced.
