服务生态系统价值共创单元的共生演化模型

Symbiotic evolution model of value co-creation unit of service ecosystem

在服务互联网环境下,服务供应链正在发展成为具有复杂、动态、协同交互特征的服务生态系统网络。针对由众多第三方服务平台、服务提供商和服务消费者组成的服务生态系统的动态演化问题,首先构建了其基于Logistic模型的共生演化模型,并采用雅各比矩阵研究了不同价值共创单元在服务生态系统中保持稳定状态的共生模式和共生条件。最后,通过数值仿真分析了共生作用系数、市场规模容量等相关因素对其共生演化的影响。仿真结果显示:服务生态系统价值共创单元的共生演化和共生作用系数与其共生模式紧密相关。在互利互惠的共生模式下,服务生态系统价值共创单元的最终稳定规模最大,是其共生演化的最佳方向;服务生态系统价值共创单元的共生演化稳定点与其自然增长率、初始规模无关,与市场容量规模有关,各类价值共创单元的市场容量规模越大,则稳定规模值越大。

In the environment of Internet of Services,the service supply chain is gradually developing into a service ecosystem network with complex,dynamic and collaborative interaction features.Aiming at the dynamic evolution of the service ecosystem of third-party service platforms,service providers and service consumers,a symbiotic evlution model based on Logistic model was developed.Then,the Jacobian matrix was used to analyze the symbiosis mode and conditions of different value co-creation units to maintain a stable state in the service ecosystem.The numerical simulation was also employed to analyze the influence of related factors on the symbiosis evolution of the service ecosystem.The simulation results showed that the symbiosis evolution of the value co-creation units in the service ecosystem was closely concerned with the symbiosis coefficient and their symbiosis mode.Moreover,under the mutually beneficial symbiosis mode,the co-creation unit of service ecosystem had the largest stable scale.Mutually beneficial symbiosis mode was the best direction for the symbiosis evolution of the service ecosystem.The symbiosis evolution stability point of the value co-creation unit of serveice ecosystem had nothing to do with its natural growth rate and initial scale,but was concerned with the market capacity scale that the larger the market capacity scale of various value co-creation units,the greater the stable scale value.
