| Beijing that its economic development in the country with a strong driving force is the study area of this paper, Beijing's industrial structure is gradually optimized with the economic transformation.Input and output data of Beijing's economy in the last two decades are select, to build an effective network of industry and explore the characteristics of topology structure, feature industry and inner sub-community structure with method of complex network, and make deduction of time, then discuss the relationship between external characteristics of industry associated network and economic development. Discussion Beijing's industry associated network's ability to resist outside interference using principle of attack, and explore the practical effect of the robust significance with an example of the relocation of Capital Iron and Steel Co.Analysis is progressing from the network structure, sub-community gathering feature, feature industry, dynamic simulation and relationship between structure and economic development, and the findings are:Firstly, It's find that, by studying the feathure of network structure, Beijing's network structure has characters of small world and free-scale in last two decades; The input-output linkages smooth degree overall industry is gradually getting better, but strong volatility in recent ten years; Important industries and important industrial relations appear staggered changes.Secondly, it's find that, by studying internal concentration of corporation, the sub-industries structure within the network associated of Beijing has a trend of first declined, then increased, last volatility, and the number of sub-communities has a trend of fluctuated upward. There are four main types of community structure:resource-based industry cluster, the energy-based industry cluster, basic livelihood of industrial clustering and the service sector concentration. There are two types industries in past years'industrial concentration, which take parts as endocentric concentration and bridges between communities.Thirdly, findings of industrial characteristics is that, Beijing experienced support from the basic industries, resource-intensive industries led to support industrial diversification, the basis of resource-intensive industry dominant, the service sector leading the situation, the development of support services leading to the increasingly prominent role, industry and people's livelihood increasing support for the status of the tertiary industry. Industries that seen from the appear frequency characteristics play a key role in Beijing's industrial development are:chemical industry, metal smelting and rolling processing industry, construction, commerce, electricity/ heat production and supply industry, freight post and telecommunications, coal Mining, paper printing and stationery industry, finance and insurance, and cultural and educational health research career.Fourthly, Through dynamics simulation analyzing, we find that The ability of unicom network of local circumstances, network conditions and network efficiency of the global response to deal with attack of robustness are enhanced, namely, which enhanced the ability to resist risks. Meanwhile, The ability of each year to deal with the attack based on the value of degree and rank are weakest, and respond to attacks based on degree of value are the strongest.Lastly, network structure have influence on economic development. At same time, Network structure parameters impact on production of value-added, but can not appear alone as explanatory variables. In-degree, rank and labor conditions in network parameters have a high correlation with the added value. And except rank the other three indices showed a positive role in promoting value-added. |
