国内外知识型产业间相互作用关系数理分析

为研究国内外知识型产业的相互作用关系,采用生态学中的Lotka-Voterra方程研究了竞争、合作及协同作用下国外知识型企业进入对国内知识型产业的影响.数理分析表明:国外知识型产业进入造成的过度竞争压力将导致国内、外知识型产业发展的负协变关系,并将导致竞争力相对较弱的国内知识型产业的衰退;适度合作关系则使国内、外知识型产业发展呈现正协变关系,并实现稳定共生;而协同作用将使二者的共生稳定点不仅优于竞争关系下的稳定点,而且帕累托优于合作关系下的稳定点,并能扩展产业的企业容量.

Quantitative analysis of interaction between domestic and overseas knowledge-based industries

The Lotka-Voterra equation is adopted for analyzing the interactions between domestic knowledge-based industry and external knowledge-based industry.Under different situations such as competition,cooperation and synthesis,the analysis results are different.It is proved that the competition overpressure caused by the entry of overseas company in China will lead to negative coordination changing relation between domestic knowledge-based industry and overseas knowledge-based industry.The positive coordination changing relation and stable symbiotic knowledge-based industry can be achieved by proper cooperation. When there is coordination interaction between domestic knowledge-based industry and overseas knowledge-based industry,the symbiotic stable point is not only better than the competition stable point but also Pareto superior to the cooperation stable point,and under this circumstance,the maximization number of companies that the knowledge-based industry can hold can be enlarged.
