Abstract: The high-speed and sound development of technological SMEs rely on high operating efficiency. Identifying the high-growth technological SMEs by GEP method, a comprehensive analysis is made to those SMEs' operating efficiency including technological efficiency and cross-efficiency, and the results reveal that the technological efficiency is often inconsistent with cross-efficiency. Based on technological efficiency and maverick index, the clustering analysis is made and the 2-year results is compared annually to identify the enterprises with high overall operating efficiency as the benchmark enterprises. The change in clustering results are further analyzed.
