基于改进Logistic模型,以节点企业的知识存量指标为量化分析指数,分析供需网企业知识协同创新的动态演化过程。通过对供需网中合作体企业与其成员企业之间的知识协同创新以及合作体成员企业之间的知识协同创新建模仿真研究,定义了企业创新驱动水平,并得出企业创新驱动水平是否相当,是维持供需网企业知识协同创新能否高效益持续稳定发展的必要条件,创新驱动水平较低的企业可以通过“阶梯式”的方式实现自身创新驱动水平的螺旋式稳定提升。这对企业选择知识协同创新伙伴,维持供需网企业知识协同创新稳定发展以及提高整个供需网企业知识协同创新效率具有一定的参考价值。

The paper analyzed the dynamic evolution of knowledge collaborative innovation among supply and demand network enterprises based on improved Logistic model, taking the knowledge stock of SDN node enterprises as quantitative indicators. From the perspective of SDN’s member enterprise, taking one kind of the typical note as example, studied the process of knowledge collaborative innovation between consortium and its’ member and two of its’ enterprises, then, simulated the above two dynamic evolution process. The article defined the innovation-driven level of enterprise and concluded that whether the level of innovation-driven come fairly or not is the essential condition for maintaining the sustainable and stable development of SDN knowledge collaborative innovation in a high efficiency. For the enterprises with low level of innovation-driven, they can achieve their stable development through the step-on circle. Which can be a good reference for SDN enterprises when they find their knowledge collaborative and is of great important to the overall SDN collaborative knowledge innovation efficiency and stability.
