This study builds and analyzes intra-trade network of export and import among European countries in social network perspective. Core-periphery of european countries is analyzed with influence and regular equivalence analysis of the trade network. The influence is analyzed with network centrality, importance, and maximum flow.
The role of the export earnings of Europe within the country in order to classify them according to the satellite network, and so were the analysis. Finally, the analysis of the satellite network, such as the analysis of the influence of combined core-core analysis, around the country, and around the nation by classifying and gave around the country against infectious effect high and low grip.
This research is the epicenter of the financial crisis the European way of European countries based on the orientation of the import and export trade, and to build up a network with a weight of social network analysis based on the trade network of gender indicators, connectivity, after analyzing the importance of national importance, such as structural indicators and trade networks, satellite analysis and Association analysis of the core-periphery countries. Also, the financial crisis through European financial or trading network by other Nations to understand the broad degree of spread and impact.
Network analysis approach in the country represented by a node (an actor), and the United States trade relations link (link) to the analysis of networks indicators recently gravity models (Gravity Model) described the developed world trade type or with a useful (Krempel amp; Pluemper, 1999, 2003). The world trade system for complex networks (complex network) is defined for the initial research indicates that a hierarchical structure, and successfully balghyeossjiman (Serrano Boguna, 2003; Garlaschelli and Loffredo, 2004, 2005), their research is different from either of the parties, such as the size or imbalance in trade relations serves do not take into account the fundamental elements of physics, with an emphasis on biological aspects in terms of phase.
So far, research and other recent research in the direction of Kali and Reyes (2010) spread of the financial crisis on the international trading network (contagion) effect. The study across the country to network-based indicators of connectedness (connectedness) using them during the financial crisis of the 1990s stock market rate of return. Also the epicenter of the financial crisis, the country is strongly linked with trade networks which are more crisis seems high, another financial crisis spread to inspire the Nations trade network strongly associated countries are showing that it can be spread.
Therefore, countries are connected through trade, and countries in crisis, because the network is transmitted on the connection type, and can be amplified. Therefore, the more dense the network connection, which can be shocking to the amplification or attenuation a dependent with a bigger potential for a ripple effect (Kali amp; Reyes, 2010). This contagious effects in a given country to finance the financial crises have occurred or in the financial sector (trade) or the real interdependence means that are propagated to other countries is higher.
This study is divided into three stages of methods and information. The first is the United Nations European regional network-building and analysis of export and import. The second step is the Trade Center of the country the network indicator, such as a satellite analysis of the structural importance. This analysis is the financial impact of the crisis on the country's trade network possibilities spread to other countries, which turned out to be the bar. The last third is a key priority and based on analysis, including satellite-close to the main trade of the exporting and importing countries, through analysis of the partners' role is to figure out.
