Abstract: The asymmetric coupling mechanisms are discovered among upstream component and downstream complement technology populations in innovation ecosystem of hi-tech Industries. This article studied empirically the coupling relations and their influencing factors of technology populations based on the density dependence model. If technology populations interact more frequently, their coupling relations are stronger. If a technology population is more important and its ownership is more concentrative, the coupling coefficients of other technology populations to it are larger.

Key words: innovation ecosystem, coupling, technology population, hi-tech industry

摘要： 高科技产业创新生态系统内上游零组件、下游互补品等不同技术种群之间相互依赖、共同进化的耦合关系存在非对称性。通过引入生态学关于生物演化密度依赖模型，实证研究表明，技术互动性越强，技术种群之间耦合强度越大；技术相对越重要，其它技术种群对此技术种群的耦合强度越大；技术所有权越集中，即技术垄断程度越高，其它技术种群对此技术种群的耦合强度越大。
