摘　　要：将网络结构熵的概念引入省际高速公路联网收费研究中。首先,建立了高速公路抽象化图论模型,在此基础上定义了收费网络结构,发现省界收费站是其中的关键因素。为研究收费网络结构变化机理,提出了收费站重要度和收费网络结构熵,并确定了网络结构熵的极值。其次,通过推导,得出省际联网收费网络结构熵大于省内联网收费网络结构熵,从而证明了实施省际联网收费的合理性。最后,提出了下一步研究的方向。In this paper, entropy theory is newly applied into the research on tolling style for expressway network. The topology of toll network is addressed by metaphysical description firstly, on the basis of which toll network structure is defined. It＇s found that inter-province border tollgate is the key element in tolling network structure. In order to clarify the translation from inner-province tolling network structure （structure A） to inter-province link tolling network structure （structure B）, note-importance and network structure entropy are defined. After comparing the entropy values of structure A and structure B, the results that structure B is more stable are got. This research supportes the government to bring inter-provinces link tolling into effect theoretically, The future research in this field is proposed finally.
