基于信息熵的中国交通运输能源消耗结构演变特征分析

Analysis of China's Transportation Energy Consumption Structure Evolution Characteristics based on Information Entropy

引入信息熵理论，计算1996年～2010年中国交通运输能源消耗结构的信息熵、均衡度及结构转换速度系数和转换方向系数，研究了中国交通运输能源消耗结构的演变特征。结果表明：中国交通运输能源消耗结构信息熵在1．3～1．46之间呈现出略微的W型波动规律；均衡度维持在0．7左右，偏大且稳定；天然气的转换方向系数持续高于其他能源。这说明中国交通运输能源消耗结构并没有发生突变，而是在稳定中缓慢变化；中国交通运输能源消耗系统能源使用多元化；中国交通运输能源消耗结构的改变主要是由于天然气消耗的增加引起的。

The introduction of the information entropy theory, calculated ：From 1996 to 2010 China＇s transportation energy consumption structure information entropy, balanced and structured conversion speed coefficient and direction of the conversion coefficient. The results showed that： Transport energy consumption structure information entropy between 1.3-1.46 and showing slightly W-tape fluctuation; Equilibrium is maintained at about 0.7, large and stable; Conversion coefficient of natural gas continued higher than other energy. This shows that China＇s transportation energy consumption structure has not mutated but slow changes in the stable; The use of China＇s transportation energy consumption system is diversification; Changes in the structure of transportation energy consumption in China is mainly due to the increase in natural gas consumption.
