以SF民机转包生产商为案例研究对象，探讨航空复杂产品创新生态系统演化的特征、原因和核心企业创新的轨迹。通过对该企业的案例研究发现，以民机转包生产商为核心企业的复杂产品创新生态系统经历了零部件转包生产、大部件制造和风险合作式研制3个阶段；每个阶段企业所面临的创新挑战呈现不同特征，既包括上游组件供应商从低一中一高的创新挑战，也包括来自客户从低一中一中的创新挑战，以及下游互补方的高水平创新挑战。揭示了创新生态系统中，组件供应商与下游互补方的创新挑战深刻地影响核心企业的创新轨迹；客户一组件供应商的动态关系推动了航空复杂产品创新生态系统演化。分析了核心企业和创新生态系统其他利益相关者的相互作用。

英文摘要：

Taking subcontract manufacturer of SF aircraft as a case, this paper discusses the feature and cause of the evolution of aviation complex product innovation ecosystem（ACPIE）, and the trajectory of innovation ecosystem affecting its core enterprise innovation. Through the case study, there are two research findings. Firstly, we find CPIE based on taking subcontract manufacturer of civil aircraft as the core enterprise has experienced three stages consisting of subcontract production of aircraft parts, large parts manufacturing, designing and manufacturing with the risk cooperation. Sec- ondly, the core enterprise is confronted with different innovation challenges in each stage： the innovation challenge of its upstream component suppliers is from low, medium to high level; the innovation challenge of customers is from low, medium to medium level; but downstream complementors discloses the high level of the innovation challenge. This study reveals that the innovation challenge of both components and complement profoundly influences the core enterprise innovation of aviation complex products in the ecosystem; the dynamic relationship between client and component suppliers is the key elements of driving the innovation ecosystem evolution. Analyzing the interaction of the core enterprise and other elements in the innovation ecosystem is also conducted.
