Empirical Research On Shenyang Automobile Industrial Network AARS Model Based On Complex Network

Recently, the research on complex network is in the ascendant, which is used widely in various fields, including mathematics,bioengineering and so on. Because of its close connection with the reality and distinct qualities of interdisciplinary, complex network has been becoming one of the newly-research hotpots with great influence in 21st century. Industrial network which is also a complex social network system is a frontier in industry economics. As the research on industrial network hasn't been carried out for a long time, the system of industrial network is immature. It is possible to introduce the complex network theories into the research on the industrial network based on the systematic complexity, and the scientific and abundant theory system can supply an effective support to the industrial network.The strategic influence of automobile industry doesn't only reflect the drive of national economy but also the powerful industrial relationship as well as high and new technology absorption. Shenyang is a tower of strength in the development of Liaoning automobile industry, and automobile is also the first pillar industry in Shenyang. However, how to grasp the opportunities, improve the industrial competitiveness and achieve great development in the background of global economic crisis and comparative lagging-development is an important and urgent issue for Shenyang. The qualities of automobile industry lead the industrial organization to the network. Therefore, an industrial network AARS model in the view of complex network is built based on the theories of SCP model and network three factors, following the logistic thought of actors-activities-resources-securities, which is used in the empirical research on Shenyang automobile industy.Aiming at the four layers and five questions, several complex network theories and methods are chosen. For example, the statistic qualities of complex network are used in the research on the industrial network density. The complex network community is used in the research on the industrial network bodies'behaviors. The complex network transmission dynamics is used in the research on the industrial network resources. The frangibility and robustness are used in the research on industrial network securities. Finally, based on the logistics thought of AA-R-S, a dynamic category system including 24 industrial network modes is built. Meanwhile, relying on the complex network dynamic theory, the evolution regime of industrial network is studied and an economic model is put forward, on the ground of which the dynamic evolution path is forecasted. Based on the in-depth study on theoretical and empirical research,some innovative conclusions are drawn as follows:(1) The density of Shenyang industrial network is low, which is reflected in both macro-density and micro-density. The conclusion accounts for the fact that the amount of collaboration between the automobile enterprises is not enough and the net relationships are very loose. Meanwhile, the industrial ecological bodies including government, education and research institutions, intermediary organizations, financial organizations have not supplied sufficient support to the enterprises and the symbiosis is in urgent to develop.(2) There are several hub enterprises in Shenyang automobile network, including automobile parts market, Jinbei vehicle, Yiqi, Shenyang Hangtian Sanling engine companies and so on. Especially, automobile parts market with highest degree is playing a very important part. Therefore, aiming at the argument whether the development of automobile parts market should be restricted, a clear attitude is suggested in the paper that the control on the automobile parts market should be loosened and more conveniences should be supplied because the development of automobile parts market is in line with current market need and economical level.(3) Based on the degree distribution and comparison identification, the topology structure of Shenyang automobile network approaches BA(m=2) scale-free network, whose two distinct qualities are growth and preferential attachment. The former quality means the scale of Shenyang automobile network will increase with the evolution of the industrial network. The latter one means the enterprises with great influence will get more resources and dominance, that is poor get poorer and rich get richer.(4) Shenyang automobile network is clustered into four communities, including part enterprise community, finished automobile community, engine community and automobile parts market community. By the analysis of the in-community, out-community and inter-subnet behaviors, some problems are found out. Firstly, the part enterprises are devoid of collaboration and the product added value together with competitiveness is very low. Most local enterprises rely on the finished automobile enterprises highly and have limited network dominance. Secondly, finished automobile enterprises are the leaders in the network, but the capability of independent innovation is very weak and the similarity of products is very high. Thirdly the harmonious relations between parts enterprises and finished automobile enterprises have not come into being, and the weakness of parts enterprises is the bottleneck of the development of proprietary brand. Fourthly,although the special car enterprises'support-rate in Shenyang is comparatively high, the lack of collaboration and small workshop production mode are the main causes of the lower R&D capability. Finally, the influence of Shenyang automobile parts market should not be neglected, and it is necessary to accelerate its development.(5) Theλof Shenyang automobile network resources diffusion efficiency is 0.0634, and the conclusion is drawn that the efficiency is not high. By the comparison between the effects of whole degree increment and part degree increment, a spiral development strategy adopting part degree increment to whole degree increment step by step can be an effective path to improve Shenyang automobile network resources diffusion efficiency.(6) Aiming at the debate about the industrial securities in the background of globalization, a clear attitude that the automobile industry security is necessary and urgent owing to its strategic influence is suggested in the paper. By the INC method put forward first in the paper, the conclusion that Shenyang industrial network is in the security state is drawn. Therefore, tactic and strategic industrial security protection are suggested in the paper. The tactic protection includes forming the crisis consciousness and supporting the development of key enterprises with strong or potential competitive advantages. The strategic protection is only to improve the international competitiveness of Shenyang automobile industry in the long-term.(7) According to the criterion based on the logistic thought of AA-R-S, the industrial network mode of Shenyang automobile network is identified as FLSG mode. Based on the complex network dynamic theory, the evolution path of Shenyang automobile network is dropped out, that is FLSG—ELSG—ELHG—ELHY—ELHG. In the process of evolution, the competitiveness of Shenyang automobile will be improved.
