6. Conclusion
Drawing on the resource-based perspective, we have proposed and examined the effects of external and internal innovation sources on the innovation performance of high-tech SMEs, and focusing on customer input in providing information on customer needs and experience, and cooperative networks in transmitting resources and capabilities, and R&D intensity in cultivating R&D capability, based on a sample of Chinese high-tech SMEs. We have revealed that customer input, network size and network duration have positive impacts on the innovation performance of high-tech SMEs. Furthermore, R&D intensity strengthens the positive impacts of customer input and network size on the innovation performance of high-tech SMEs. These findings provide significant research and managerial implications for high-tech SMEs in the context of emerging economies like China.
