基于内生性与外生性的研发网络演化机制研究
发布时间：2018-07-20 15:33
【摘要】：针对研发网络演化过程中只考虑单一的内生性或外生性影响因素存在的不足,结合企业平等自愿的合作原则,综合了研发网络演化过程中内生性与外生性两个因素,从企业间合作关系的确立和企业退出网络两方面构建了双向择优网络演化模型。最后进行了模拟仿真,结果发现:研发网络演化模型具有无标度、小世界的特征;研发网络经历了起始、成长、稳定和衰退四个阶段,且每个阶段网络呈现出不同的规律性特征;稳定期的研发网络平均收益最大,知识溢出率对网络利用效率具有显著影响,这为研发网络的健康持续发展及政府正确制定宏观政策提供了理论依据。利用电信行业的研发网络对上述理论模型进行验证,模型与实际网络基本吻合,在一定程度上检验了模型的正确性。
[Abstract]:In view of the deficiency of considering the single endogenous or exogenous factors in the process of R & D network evolution, combined with the principle of equal and voluntary cooperation of enterprises, this paper synthesizes the endogenous and exogenetic factors in the process of R & D network evolution. The evolution model of bidirectional preferential network is constructed from the establishment of inter-firm cooperative relationship and the withdrawal of enterprises from the network. Finally, the simulation results show that the evolution model of R & D network has the characteristics of scale-free and small world, and the R & D network has gone through four stages: beginning, growing, stabilizing and declining. The average income of R & D networks in stable period is the largest, and the knowledge spillover rate has a significant impact on the efficiency of network utilization. This provides a theoretical basis for the healthy and sustainable development of R & D network and the correct formulation of macro-policy by the government. The theoretical model is verified by the R & D network of telecommunication industry. The model is basically consistent with the actual network, and the correctness of the model is verified to a certain extent.
