Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

This chapter, by using the theory of public interests of the government control, control-capture theory, the theoretical model of the government control, the minimum government control theory construed the basic contents covered by the government control, and discussed the interactivity and the nonnegligible effects of the government control and the industrial development model. Theses theories provide the convictive constructions to some practical economic problems that cannot be satisfactorily constructed by the traditional economic theories. Thus it makes possible for us to look on the reasons for control rules formulated by the government and some other institutional problems in the industrial evolvement, and analyze the costs of the government control and the restrictive factors and significances of the institutional changes whereof in a never-before-used angle.

With complex system and behavioural finance theory, a multi-agent trade market model is primarily built. Furthermore a relevant information auto- retrieval platform based on Internet, a background-based distributed computing platform for apperceiving agent and a simulated real-time trade system are primarily realized. Both experimental results and theoretical analyse show that effective market hypothesis as support for capital market and capital asset pricing theory (Nobel Prize in economics in 1990) are defective. These results also verify the feature of GARCH model (Nobel Prize in economics in 2003). Moreover, a quantitative analytic way to behavioural capital asset pricing theory (Nobel Prize in economics in 2002) in behavioural finance is presented.
