【摘要】：為了實(shí)現(xiàn)有限運(yùn)輸資源的合理配置和高效利用,基于信息熵理論和主導(dǎo)產(chǎn)業(yè)擴(kuò)散效應(yīng)理論,通過定義綜合運(yùn)輸體系結(jié)構(gòu)信息熵、均衡度、優(yōu)勢度、轉(zhuǎn)換速度系數(shù)和轉(zhuǎn)換方向系數(shù),分析了1949—2014年間我國綜合運(yùn)輸體系結(jié)構(gòu)的演變特征及趨勢。研究結(jié)果表明:我國綜合運(yùn)輸體系結(jié)構(gòu)信息熵不斷增加并逐步趨于平穩(wěn),呈現(xiàn)出"階梯型"變化趨勢;均衡度、優(yōu)勢度呈現(xiàn)出"∞"型變化趨勢,表現(xiàn)出兩階段的發(fā)展特征;我國綜合運(yùn)輸體系結(jié)構(gòu)轉(zhuǎn)換速度系數(shù)和轉(zhuǎn)換方向系數(shù)前期偏低且差異較小,后期達(dá)到較高水平且差異明顯。綜合運(yùn)輸理念和實(shí)踐不斷發(fā)展,各種運(yùn)輸方式通過其技術(shù)經(jīng)濟(jì)特征確立了交通運(yùn)輸新格局,交通運(yùn)輸發(fā)展應(yīng)按照運(yùn)輸方式各盡其能進(jìn)行資源優(yōu)化配置,形成合理、均衡、高效的綜合運(yùn)輸體系結(jié)構(gòu)。
[Abstract]:In order to realize the rational allocation and efficient utilization of limited transportation resources, based on the information entropy theory and the diffusion effect theory of leading industries, this paper defines the information entropy, equilibrium and dominance of the integrated transportation system structure.This paper analyzes the evolution characteristics and trends of the integrated transportation system structure in China from 1949 to 2014.The results show that the information entropy of the integrated transportation system in China is increasing and gradually becoming steady, showing a "ladder" trend, a "鈭，
