| 摘 要： | 由于影响因素的复杂性,交通运输结构的研究多以简单的比例关系结合定性分析为主,缺乏定量评价的客观依据.本文尝试应用信息熵理论对区域交通运输结构的演变和发展规律进行定量研究.首先,提出交通运输结构信息熵,并构建了交通运输结构的均衡度和优势度指标,用于衡量交通运输结构及其演变规律.在此基础上,运用主成分分析与灰色关联分析相结...

| Abstract: | Because of the complex influencing factors,the research on transportation structure usually based on a simple combination of qualitative analysis and ratio-based relation,which lacks of objective quantitative evaluation.The paper applies the information entropy theory to quantitatively study the evolution and development law for regional transportation structure.First,the transport structure information entropy is proposed,and a balanced transportation structure and dominance indicators is proposed to measu... |
