We developed an evaluation model to make a general metrics for circular economy system of industrial chains. The development of the evaluation tree drew upon five factors to identify the structural complexity. The evaluation model generated unitive entropy information from six data definition （node, level of community, metabolic span, degree of node, number of relation and connectivity of node） according to the evaluation tree. The industrial chains of Tashan circular economy park of Datong Coal Mine Group and Gujiao circular economy park of Xishan Coal-Electricity Group were evaluated by the proposed method. The key factors stunted by the decline of structural complexity were identified and the unitive metrics of entropy information of the industrial chain was shown for realigning the circular economy systems.展开更多

However, the development of cruise in China is in its starting stage, though it is already mature in foreign market, having some problems like immature development pattern and prominence of structural unbalance on supply and demand of cruise travelling. This paper studies the driving mechanism, developmental pattern and achievement path of developing Shanghai cruise traveling in order to attract cruise customers from home and abroad and build high-end, luxury, high-quality and able to provide better experience for customers cruise services based on cruise resource on in Shanghai.展开更多

文摘The central characteristic of cruise industry is providing modernized service, which has gradually become the high level with the fastest developing speed and enormous growing potentiality in the intemational traveling market in recent years. However, the development of cruise in China is in its starting stage, though it is already mature in foreign market, having some problems like immature development pattern and prominence of structural unbalance on supply and demand of cruise travelling. This paper studies the driving mechanism, developmental pattern and achievement path of developing Shanghai cruise traveling in order to attract cruise customers from home and abroad and build high-end, luxury, high-quality and able to provide better experience for customers cruise services based on cruise resource on in Shanghai.
