分析研发在网络安全类企业中的地位，并基于数据包络分析的 BCC 模型和超效率模型对我国沪深两市上市的21家网络安全类企业的研发效率进行评价。结果表明，BCC 模型下综合效率达到 DEA 有效的网络安全企业占比不到一半，部分企业的无效率主要是规模无效造成的；超效率 DEA 模型可以对 BCC 模型下综合效率有效的企业进行比较和分析。此外还对研发活动综合效率无效的网络安全类企业的投入产出进行改进分析并提出相关政策建议。
分析研髮在網絡安全類企業中的地位，併基于數據包絡分析的 BCC 模型和超效率模型對我國滬深兩市上市的21傢網絡安全類企業的研髮效率進行評價。結果錶明，BCC 模型下綜閤效率達到 DEA 有效的網絡安全企業佔比不到一半，部分企業的無效率主要是規模無效造成的；超效率 DEA 模型可以對 BCC 模型下綜閤效率有效的企業進行比較和分析。此外還對研髮活動綜閤效率無效的網絡安全類企業的投入產齣進行改進分析併提齣相關政策建議。

This paper makes a brief analysis on the importance of R&D investment in network security enterprises,and then an empirical study is taken to evaluate the efficiency of R&D activities in 21 network security listed companies in China by BCC model and Super -Efficiency model of data envelopment analysis.The results show that the overall efficiency of less than half companies (in the 21 enterprises selected)can reach DEA valid state in BCC model;some of the companies which are non -DEA efficiency are mainly caused by invalid scale.Using super -efficiency model can make a comparative analysis on those companies which are DEA efficiency under BCC model.Additionally,This paper makes an improvement analysis on R&D activities in network security enterprises,and some relative policy recommendations are made to enhance R&D capabilities and to achieve optimal size for network security enterprises.
