本文基于数据包络分析的BCC模型和超效率模型,对我国18个较有影响的新闻类网站的信息传播效率进行评价并给出相应对策建议。结果表明:超效率模型确实能够对所有决策单元进行充分评价和排序。整体来看,18个财经资讯网站中有9个网站在BCC模型下综合效率达到了DEA有效,SE-DEA模型可以对这些DEA有效的网站进行比较和排名。分季度来看,6个季度中有4个季度综合效率达到有效的网站接近一半。
Based on the BCC model and super efficiency model of data envelopment analysis, this paper evaluates the information dissemination efficiency of 18 influential news websites in our country and gives corresponding countermeasures and suggestions. The results show that the super-efficient model can indeed evaluate and sort all the decision-making units adequately. Overall, 9 out of 18 financial information sites are effectively DEA-efficient under the BCC model and SE-DEA models allow comparison and ranking of these DEA-effective websites. Quarterly, nearly half of all four quarterly integrated efficiencies were valid in six quarters.
