受制于地形,西部地区开展交通行业的成本较高。因此,交通一直是西部地区的短板。近年来,国家注重物流业的发展,对西部陆海新通道的重视程度日益提升。基于2003—2021年西部陆海新通道沿线81个地级及以上城市的面板数据,采用泰尔指数衡量城乡收入不平等程度,研究交通质量效率对沿线地区城乡收入不平等程度的影响。研究发现:第一,西部陆海新通道交通质量效率对沿线地区城乡收入不平等程度具有显著的改善作用,这一结论在替换变量、更改研究样本容量、内生性检验等检验后仍然成立;第二,交通质量效率对沿线地区城乡收入不平等程度的影响存在空间溢出效应;第三,交通质量效率主要通过提高金融效率、推动城镇化进程两条机制改善沿线地区的城乡收入不平等程度;第四,交通质量效率与城乡收入不平等程度之间存在非线性关系。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});$(document).ready(function(){window.metaData = {"journal":{"issn":"1000-5072","qiKanMingCheng_CN":"暨南学报（哲学社会科学版）","id":2,"qiKanMingCheng_EN":"Jinan Journal"},"article":{"keywordList_cn":["西部陆海新通道","交通质量效率","城乡收入不平等","门槛效应"],"juan":"47","zhaiyao_cn":"受制于地形,西部地区开展交通行业的成本较高。因此,交通一直是西部地区的短板。近年来,国家注重物流业的发展,对西部陆海新通道的重视程度日益提升。基于2003—2021年西部陆海新通道沿线81个地级及以上城市的面板数据,采用泰尔指数衡量城乡收入不平等程度,研究交通质量效率对沿线地区城乡收入不平等程度的影响。研究发现:第一,西部陆海新通道交通质量效率对沿线地区城乡收入不平等程度具有显著的改善作用,这一结论在替换变量、更改研究样本容量、内生性检验等检验后仍然成立;第二,交通质量效率对沿线地区城乡收入不平等程度的影响存在空间溢出效应;第三,交通质量效率主要通过提高金融效率、推动城镇化进程两条机制改善沿线地区的城乡收入不平等程度;第四,交通质量效率与城乡收入不平等程度之间存在非线性关系。","endNoteUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=EndNote&id=7245","reference":"","bibtexUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=BibTeX&id=7245","abstractUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/10.11778/j.jnxb.20242248","qi":"7","id":7245,"nian":2025,"bianHao":"1757058996892-1700525448","zuoZheEn_L":"YANG Shanshan","juanUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/Y2025","shouCiFaBuRiQi":"2025-09-05","qiShiYe":"159","qiUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/Y2025/V47/I7","lanMu_cn":"经济管理","pdfSize":"1961","zuoZhe_CN":"杨珊珊","risUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=Ris&id=7245","title_cn":"交通质量效率与城乡收入不平等——基于西部陆海新通道沿线地级市的实证分析","doi":"10.11778/j.jnxb.20242248","jieShuYe":"179","keywordList_en":["new western land and sea corridor","transportation quality efficiency","income inequality between urban and rural areas","threshold effect"],"endNoteUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/article/getTxtFile.do?fileType=EndNote&id=7245","zhaiyao_en":"The improvement of transportation facilities has been seen as an important means of raising income in China. Compared to the eastern region, the terrain in the western region is dominated by mountains, plateaus, and basins, making it more expensive and difficult to carry out the transportation industry. Consequently, to enhance the transportation capacity and the quality and efficiency of logistics development in the western region, China has issued the Master Plan for New Western Land and Sea Corridor, actively promoting the construction of the new western land and sea corridor and the development of a multimodal system of land transportation, inland waterway transportation, and air transportation. However, most income disparity studies tend to focus on the impact of transportation infrastructure and fail to look at the key factor of transportation quality efficiency.This paper comprehensively examines the four modes of transportation, namely, railroads, highways, water transport, and civil aviation, and refers to the research results of scholars such as Tian and Ran and Li and Tu, to comprehensively assess the efficiency of the transportation quality in the regions along the new western land and sea corridor, and quantifies the degree of urban-rural income inequality using the Theil index, and then empirically examines the role of the efficiency of the quality of transportation in affecting urban-rural income inequality. This paper finds that the efficiency of transportation quality in the new western land and sea corridor significantly reduces urban-rural income inequality in the regions along the routes, and this finding remains robust after dealing with endogeneity, replacing the urban-rural income inequality measure, and adjusting the sample size. Mechanism analysis suggests that this ameliorative effect is achieved through two main paths: improving financial efficiency and promoting urbanization. Further analysis of the threshold effect shows a non-linear relationship between the efficiency of transportation quality and the degree of urban-rural income inequality when urban per capita disposable income and rural per capita disposable income (per capita net income) are taken as threshold variables.Compared with existing studies, the innovations of this paper are mainly in the following aspects. Firstly, taking into account the actual situation of the western region and the national policy orientation, this paper focuses the research perspective on prefecture-level and above cities along the new western land and sea corridor, and uses the total passenger transport volume/total household population and the total freight transport volume/built-up area to comprehensively measure the efficiency of the transportation quality and examine its impact on the urban-rural income inequality. Secondly, this paper provides an in-depth analysis of how the efficiency of transportation quality affects urban-rural income inequality, i.e., it explores the specific paths through which it works. Finally, this paper uses a threshold model to further investigate whether there is a nonlinear relationship between transportation quality efficiency and the urban-rural income inequality. This paper provides a new theoretical and empirical basis for understanding the role of transportation quality and efficiency in the coordinated development of the regional economy, and actively helps the government to make scientific decisions on transportation infrastructure investment and planning. Additionally, this paper reveals the complex relationship between transportation quality and efficiency and the urban-rural income inequality, which helps prefecture-level cities to introduce more targeted policy measures to promote balanced urban-rural development and realize common prosperity.","bibtexUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=BibTeX&id=7245","abstractUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/10.11778/j.jnxb.20242248","zuoZheCn_L":"杨珊珊","juanUrl_cn":"https://jnxb.jnu.edu.cn/skb/CN/Y2025","lanMu_en":"","qiUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/Y2025/V47/I7","zuoZhe_EN":"YANG Shanshan","risUrl_en":"https://jnxb.jnu.edu.cn/skb/EN/article/getTxtFile.do?fileType=Ris&id=7245","title_en":"Transportation Quality Efficiency and Urban-Rural Income Inequality: Empirical Analysis of Cities along the New Western Land and Sea Corridor","hasPdf":"true"},"authorNotes_cn":["杨珊珊,重庆大学经济与工商管理学院。"]};if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
