摘要:

为优化内陆出境交通系统布局,提升跨境运输韧性,构建“敏感性-应对性”双维度评价指标体系,综合集对分析模型、空间马尔可夫链与障碍度模型,系统解析中国内陆225个城市的脆弱性动态特征及其驱动机制。结果表明:脆弱性呈现显著的多极分化与空间俱乐部收敛特征,随时间演化脆弱性整体逐年降低,且由两极化向多极化演变,绝对差异减小。脆弱性具有显著空间自相关特征和空间溢出效应,形成“高脆弱性沿边集聚,低脆弱性以城市群为中心扩散”的空间格局,邻域背景通过路径依赖制约脆弱性演化方向,邻域低脆弱性环境可使城市脆弱性向下转移概率提升64.5%。货运周转量和进出口贸易总额障碍因子的作用逐年减弱;内陆-口岸公路最短旅行时间障碍效应从相对稳定逐渐转为持续上升;城市枢纽等级和连接度对非枢纽城市脆弱性构成显著制约。

Abstract:

To optimize the layout of the outbound transportation system and enhance system resilience, a "Sensitivity-Response" dual-dimensional evaluation index system was constructed. The comprehensive methods including set pair analysis, spatial Markov chain, and obstacle degree model were used to analyze the dynamic characteristics and driving mechanisms of vulnerability in 225 inland cities in China. The findings reveal that vulnerability demonstrates significant multi-polarization and spatial club convergence. The overall vulnerability decreases annually, evolving from bi-polarization to multi-polarization, with a reduction of absolute difference. Vulnerability exhibits significant spatial auto-correlation and spillover effects, forming a spatial pattern where "high-vulnerability is clustered along the borders, while low-vulnerability diffuses from urban agglomerations". A low-vulnerability neighborhood environment increases the probability of a city's vulnerability transferring downward by 64.5%. The obstructive effects of both freight turnover volume and total import-export trade value weaken annually. In contrast, the hindering effect of shortest inland-port road travel time shifts from a relatively stable to a consistent increase. Furthermore, city hub level and connectivity impose significant constraints on vulnerability of non-hub cities.

Key words: inland areas, vulnerability of outbound transportation systems, spatio-temporal evolution, spatial spillover effects, obstacle factors
