Abstract: During the development of transportation industry, the change Of industry structure could cause the change of transportation structure. This paper makes a quantitative study of the correlation of the industry structure and transportation structure by using cause and effect relationship test of the entropy theory. The results shows that the change of industry structure has nothing to do with the structure of freight quantity, but has causal relationship with the structure of freight turnover quantity. This paper aims to provide new methods for researching the correlation of the structure of industry and transportation.

Key words: industry structure, transportation Stricture, entropy, causal Relationship

摘要： 在交通运输业发展演进过程中，产业结构的变化会带动交通运输结构变化.通过对产业结构与交通运输结构熵值的因果关系检验，从定量的角度来分析我国的产业结构与交通运输结构的关系.检验结果表明，产业结构的变化与货运量结构变化没有直接的关系，而与货运周转量结构变化有因果关系.本文目的在于为研究产业结构与交通运输结构相互关系提供一种新的思路.
