长吉城际铁路对区域可达性的影响分析

Analysis on Influence of Changchun-Jilin Intercity Railway on Regional Accessibility

长吉城际铁路作为我国东北地区铁路系统的重要组成部分,对于促进长春、吉林两市经济社会发展,加速吉林省中部城市群发育具有重要作用。利用引力模型分别对基于城镇居民人均可支配收入和农民人均纯收入的区域可达性进行测算。实证研究表明,长吉城际铁路的开通使得两市区域可达性增长近10倍,极大地促进了两市的交流合作,对于增强长春、吉林两大中心城市对周边城市的辐射、带动作用,加速吉林省中部城市群的进一步发育具有重要作用。

Changchun-Jilin intercity railway, as an important part of railway system in northeast area of China, has an important role on promoting the development of Changchun and Jilin cities economic society and accelerating the urban agglomeration development in central of Jilin provinqe.
