本文综合运用数据包络分析的松弛测度模型和临界效率测度模型，对中国高技术产业技术创新活动的技术效率、纯技术效率、规模效率、规模状态进行了测度。研究表明，虽然中国高技术产业纯技术效率在逐年改善，但规模效益较差，规模效率逐年削弱，且生产规模处于最优状态的份额仅占考察状态的38％。研究还发现，无效高技术产业技术改造经费投入冗余较为严重，多数无效高技术产业在新产品出口和专利产出上存在较大的潜在产出不足。
本文綜閤運用數據包絡分析的鬆弛測度模型和臨界效率測度模型，對中國高技術產業技術創新活動的技術效率、純技術效率、規模效率、規模狀態進行瞭測度。研究錶明，雖然中國高技術產業純技術效率在逐年改善，但規模效益較差，規模效率逐年削弱，且生產規模處于最優狀態的份額僅佔攷察狀態的38％。研究還髮現，無效高技術產業技術改造經費投入冗餘較為嚴重，多數無效高技術產業在新產品齣口和專利產齣上存在較大的潛在產齣不足。

The paper measures the performances of technical efficiency, pure technical efficiency, scale efficiency, scale status in virtue of the slack-based meas- ure and the critical efficiency measure in data envelopment analysis （DEA） . The measurement results show that although the pure technical efficiency is improving year by year, the scale economy is poor and the scale effect is gradually weakening, along with the fact that the states with optimal productive scale only share 38 % of all inspected states. At the same time, the analysis results also show that the sur- plus degree of inputs of technological renovation into innovation activities of inefficient high-tech industries is serious, and there is heavy shortage of potential outputs in the products export and inventive patents for most of inefficient high-tech industries.
