摘要
运用因子分析和效率测度模型,对2010年我国20家主要上市软件公司的经营效率进行评价。结果表明:除远光软件等8家软件公司处于效率前沿面外,其余均规模无效率,且大多数无效率软件公司处在规模报酬递增阶段,具有较好的规模收益潜力。进一步采用DEA无效率单元的差额变数分析发现,大多数无效率软件公司均存在不同程度的投入冗余和产出不足,各类要素冗余投入存在很大的调整空间。提出提高上市软件公司经营效率的政策建议:适度的规模扩张,注重规模带来的经济效益;加强技术利用,着力提高资源转化效率。
Based on combined methods of factor analysis （DRF） and Super-etiiclency DEA model （SE-DEA）, this paper evaluates the operating efficiency of China＇s 20 major listed software companies in 2010. The result shows that,except that Yuanguang software and other seven software companies have integrated efficiency, pure technical efficiency and scale efficiency at the same time, the rest sofeware companies have invalid scale efficiency. In addition, most invalid software companies are in the stage of increasing returns to scale and have a good potential for returns to scale. Further study by using SEA shows that most invalid software companies have varying degrees of {nput redundancy and output defi- ciency and there is also a big room of adjustments of all kinds of factor redundancy. Finally,in accordance with the above analysis, this paper puts forward several policy recommendations on how to improve the operating efficiency of list software companies.moderate scale enlargement, emphasis on economic bene- fits brought by scales and strengthening of technological use so as to increase the efficiency of resource transformation.
