International Crude Oil Price Stability Based On Complex Network

As the lifeblood of the national economy of a country, oil not only affects country's economy, but also has a significant impact on the regional and even worleconomy. Therefore, no matter the developed or developing countries, oil, as important strategic material, have attached great importance to the stability of oprice.In the foundation of symbolic dynamics theory and complex network theory, awell as the basis of original data transformation and network-integration softwa–Ucinet, we put forward a complex network of international crude oil price modeDuring the process in the analysis of the basic topological properties, we derive the oprice network have both the small world and scale free characteristics. We constructeevolution model of the oil price network, and simulation results show the rationalitof the modelOn the basis, Build a comprehensive centralized index system of the oil pricnetwork, we get the centre nodes from computing the centric level. On the other hansimulated node-attack in four ways and then analyze the structure and efficiencbefore the attack and after. By means of analyze network topology characteristics anthe level of centration, come up with the model of oil price mode, and focused on trelationship between the critical oil price threshold TC and different attack strategiethen arrive oil price changes cascade mode stability and stability in the phastransition mode.
