中文摘要：

在企业占有市场的模型分析中,运用分支理论和动力学系统理论,发现企业在等价的同一产品中对科研投资和广告宣传产品的力度进行调整时,会导致企业在一定的市场中所占有的市场份额出现分支;并随科研投资和宣传产品资金的增加,企业所占市场份额会进入混沌状态.

英文摘要：

Using the theory of bifurcations and dynamical systems to analyze the model of market occupying for enterprises,we find that the companies adjusting the investment with the equal price in scientific research and commercial advertisement for the same product will lead to embranchment in the markets that the companies have already occupied with a certain percentage.Along with the increase of investment capital,the quota of the occupied markets will turn into a chaotic state.
