Research On Network Analysis Of Stock Market Of "Silk Road Economic Belt" Based On Complex Network

With the rapid development of China's economy,more and more people are paying attention to the stock market,so the research on the relationship between stocks and shares becomes very important.Whether stocks have influence can be analyzed through the discipline of complex networks.In recent years,researchers will study the combination of complex networks and the financial sector,the stock market is the key research objects,but most scholars to study and analysis on the existing stock market."One Belt And One Road" is short for "silk road economic belt" and "21st century maritime silk road",which was proposed by President xi jin ping of China in September and October 2013.The proposal of the strategic concept makes the economic development of the people in the relevant area also increase correspondingly.This paper analyzes and studies the stock market network model of 13 provinces(municipalities directly under the central government)through the silk road economic belt.In this paper,the stocks of companies listed in the 13 provinces(municipality directly under the central government)from September 2012 to September 2014 are studied,and the combination of the idea of complex network and stock market is analyzed.Firstly,based on the threshold method,the stock network of "silk road economic belt" was constructed and the static characteristics and topological properties of the network were analyzed.Then the key nodes in the stock network are identified and the transmission process and robustness analysis are carried out.Then,the corporate structure of the stock network is divided and some reasonable opinions are given to investors to help them effectively avoid risks.Finally,a hysteresis network is established to analyze the structural changes of the stock market network before and after the strategic conception.The first chapter describes the background,significance,domestic research status,research methods and contents of the thesis.The second chapter introduces the definition of complex network including static geometry,topological properties and centrality index.In the third chapter,we construct the stock network and analyze the statistical characteristics of the stock network,and find that the established stock network is the unmarked small world network.The fourth chapter,first of all,based on the efficiency of the transmission distance centralized index to identify the key node,using SIR model analysis of key node transmission capacity,and then create new centralized index based on evidence theory through share network robustness analysis of the influence of key nodes;In chapter 5,the corporate structure of the stock network is divided,and it is found that the large associations in the stock network are divided by industry and then give reasonable opinions and Suggestions to the investors.In chapter 6,the network of stock network is established and the structure of the stock network is more stable after the policy is put forward.
