基于创新企业与服务机构二分网络的服务关系嵌入策略及其演化研究

Research on the service relation embedding strategy and evolutionary based on the bipartite network of innovation enterprises and service institutes

摘要:

技术创新及其社会化服务之间相互促进、相互影响，形成了基于创新企业与服务机构间服务关系的“多对多”的二分网络。在服务关系嵌入二分网络的过程中，服务机构在选取创新企业上具有模仿性和自主性，分别对应着择优选择策略和随机选择策略；随着时间的演变，二分网络中的服务关系不断地发生断开与重连。在演化稳定状态下，依据不同的择优选择概率，节点的连通度分布服从二项分布、具有指数截断的幂律分布和脉冲分布；实证分析与计算实验也证实了这三种分布的存在。创新与服务二分网络的结构分析对于产业政策的制定有着重要意义。

Abstract:

Technological innovation promote and affect each other, so enterprises and service organizations form the many-many bipartite network based on service relations. During the process of service relations embedding to the bipartite network, service organizations have characteristics of imitative and autonomy, which response to preferential selection strategy and random selection strategy respectively. With the evolution of bipartite network, service relations break and rewire constantly. When bipartite network evolves to the stable status, the degree distribution of nodes follows three kinds of distribution: binomial distribution, power-law distribution and pulse distribution respectively. The empirical analysis and computing experiments have also proved them. The structure analysis of the bipartite network of innovation and service have an important significance to design the policy of industry development.
