摘要：This paper analyzes how imitation and innovation strategies of high-tech small and medium-sized enterprises (SMEs) impact their sustainable performances and also the whole business ecosystem with the NK-model that mimics the fitness landscape and simulates enterprises’ choice of technological strategy in response to causal ambiguity and environmental complexity. Our study yielded three findings: (1) When the imitation barriers are low, the imitation strategy of high-tech SMEs has a better effect on the performance improvement in the early stage of the operation than the innovation strategy. In the long run, high-tech SMEs exhibit innovation, which plays a greater and more lasting role in enhancing sustainable performance. On the contrary, it is always difficult for imitators to realize significant performance improvement, (2) In a simple environment, imitation strategy plays a more effective role in improving high-tech SMEs’ performance, whereas in a complex environment, innovation strategy is more conducive to discovering opportunities, and it issues from high levels of competition, and (3) more importantly, the simulation finds that the innovation of high-tech SMEs contributes more to the performance of the business ecosystem as a whole. The introduction of the NK-model simulation method in the research of technological strategies and the new scope of looking at the strategies in the business ecosystem provide new research venues for the literature.
