Within the context that global scientific and technological innovation continues to break through discipline constraints and achieve cross-domain group breakthrough development, large enterprises are constantly seeking new ways of opening and enabling. Corporate venture capital (CVC) has become an important way for large enterprises to seize knowledge, achieve symbiotic innovation, and explore external resources. By employing the bionics research method and focusing on the symbiosis mechanism between large enterprises and start-ups, this paper conducts an in-depth analysis on the symbiosis motivation, the composition of the symbiosis system, and the symbiosis environment, and explores the evolutionary simulation after the increase or decrease of resource capacity, the intrusion of the innovation population, or the equipotential integration into the innovation ecosystem when the external environmental factors change to verify the coordinated development within the enterprise population and between the enterprise population and the environment. The results show that: (1) The symbiosis, self-consistency, evolution, spillover, and other effects within the CVC ecological community fully realize the “positive sum game” process of both sides; (2) The large enterprise population and entrepreneurial enterprise population in the CVC ecological community form a two-dimensional symbiotic system; and (3) When the resource capacity of the innovation ecosystem changes, the innovation population invades the system with a strong jump in the queue, and the innovation population participates in the system with a weak allelic fusion. This paper points out the influence, interaction, and evolution development laws between enterprise species, enterprise groups, and the innovation system environment and enriches and expands the theory of the relationship between venture capital and enterprise innovation.

在全球科技创新不断突破学科约束、实现跨领域群体突破发展的背景下，大型企业也在不断寻求新的开放赋能方式。企业风险投资（CVC）已成为大型企业获取知识、实现共生创新、开拓外部资源的重要途径。运用仿生学研究方法，聚焦大型企业与初创企业的共生机制，对共生动机、共生系统构成、共生环境进行深入分析，探索演化模拟资源容量增减后，创新种群的入侵，或在外部环境因素发生变化时等势融入创新生态系统，验证企业群体内部、企业群体与环境之间的协调发展。结果表明：（1）CVC生态社区内部的共生、自洽、进化、溢出等效应充分实现了双方的“正和博弈”过程；(2) CVC生态社区中的大企业群体和创业企业群体形成二维共生系统；(3)当创新生态系统的资源容量发生变化时，创新种群以强插队方式侵入系统，创新种群以弱等位基因融合方式参与系统。本文指出影响，
