By using the means of time series analysis, the input-output, Markov processes and the modern matrix analysis, the limiting problem of price balance and vibration in stochastic economic environment has been researched, and surprising conclusions obtained are as following： the probability that the economic collapse time is equal ∞ is 0.展开更多

A kind of linear space regional scathetic bodyforms constantly and develops rapidly. Relying on the traffic trunk lines, it aggregates and diffusesconstantly.At the same time, it mixes population, industry, town, interflow of commodities, interflowof energy and interflow of information together.This unique space regional synthetic body is calledtraffic economic belt (TEB). In the paper, the basic concepts, types and qualities of TEB wereelaborated and the life-circle theory was put forward creatively.展开更多
