全球化背景下核型创新网络竞争机制研究——基于改进LV-EG模型的仿真分析

Study on Competition Mechanism of Core-structure Innovation Network under the Circumstance of Globalization-A Simulation Study Based on LV-EG Model

在全球化背景下,核型创新网络在向全球创新网络演进的过程中面临多市场竞争和关键资源竞争的双重考验。首先构建全球市场环境下核型创新网络多层次竞合模型;其次,运用Lotka-Volterra模型和演化博弈模型分别剖析核心企业间的竞争关系和尾端企业间的竞合关系,并据此构建改进的LV-EG模型以分析尾端企业竞合关系对核心企业间竞争关系的作用机理;最后,运用matlab对改进的LV-EG模型进行仿真。仿真结果表明:核心企业的尾端企业报酬支付能力、创新产品生产能力、创新环境和网络结构对核型创新网络在全球范围内吸引优质企业并在全球市场环境中获取竞争优势具有重要影响。

Under the circumstance of globalization, core-structure innovation network faces dual challenge of multi- market competition and key resources competition in the process of development where the revolution of core-struc- ture innovation network is to global innovation network. Therefore, we firstly establish the model, of core-structure innovation network＇ s multi-level coopetition under the global market environment. And then we expound core- firms＇ competition and end-firms＇ coopetition by applying and the Lotka-Volterra model and the evolutionary game model. Finally, we simulate and analyze this process by applying matlab software to the LV-EG model and come to the conclusion that core-firm＇ s ability of paying to end-firms and production capacity of innovative products , the innovation environment and the network structure influence greatly on core-firms＇ ability to attract end- firms from the global world and core-firms＇ s competitive advantage under the global market environment.
