【摘要】：运用非参数DEA方法和参数SFA方法,对我国2001—2010年30个省级行政区信息服务业技术效率进行比较分析。结果表明:DEA和SFA方法测算技术效率平均值存在显著差异,但高度相关,达到68.3%;排序方面呈现较强的一致性,达到70.6%。SFA方法则算得到的全国、东中西部地区技术效率值均呈现明显收敛趋势,DEA方法测算的技术效率值均呈现绝对β趋同。DEA和SFA技术效率值与信息服务业经济绩效均呈现显著的正向相关。同时运用两种方法进行评价,可以实现非参数方法和参数方法的优势互补,增强评价结果的可信度和稳健性。
[Abstract]:By using non-parametric DEA method and parametric SFA method, the technical efficiency of information service industry in 30 provincial administrative regions of China from 2001 to 2010 is compared and analyzed. The results show that there are significant differences in the average value of technical efficiency between the two methods, but they are highly correlated. Up to 68.3%; there is a strong consistency in ranking, 70.6. The SFA method can be counted as the whole country. The technical efficiency values of East, West and West China showed obvious convergence trend. The technical efficiency values measured by DEA showed absolute 尾 -convergence. DEA and SFA technology efficiency values showed significant positive correlation with the economic performance of information service industry. Using two methods to evaluate, The nonparametric method and the parametric method can complement each other and enhance the reliability and robustness of the evaluation results.
