基于共享投入两阶段DEA模型的通信企业标准化效率研究

Research on Technical Standardization Efficiency of Telecommunication Enterprises Based on Two-Stage DEA Model with Shared Inputs

摘要:

在国家标准化政策和战略的指导下,通信企业提升标准化效率对中国发展通信产业和数字经济具有重要的战略意义。从通信产业技术标准研发投入和标准化经营成果产出的视角,提出了通信企业标准化效率评价指标体系,并构建了可变规模报酬下的两阶段数据包络分析模型来测度通信企业技术标准研发效率和标准化成果转化效率。针对华为和中兴两家企业2010-2020年的投入产出数据测算结果表明,两家公司技术标准化整体效率较高,子阶段个别年份效率低下。在技术标准研发阶段,华为的效率平均值低于中兴的效率平均值；在标准转化阶段,华为的效率平均值高于中兴的效率平均值。最后,针对研究结果所反映的企业标准化过程中的问题提出相应的对策与建议。

Abstract:

Under the guidance of national standardization policies and strategies, it is of strategic significance for telecommunication enterprises to improve their standardization efficiency for the development of telecommunication industry and digital economy in China. From the perspectives of technical standard R D investment and standardization business results output in the telecommunication industry, an evaluation index system for standardization efficiency of telecommunication enterprises is proposed. A two-stage data envelopment analysis model under variable scale remuneration is constructed to measure the technical standard R D efficiency and standardization results transformation efficiency of telecommunication enterprises. The results of input-output data measurement for Huawei and ZTE from 2010 to 2020 show that the overall efficiency of technical standardization of the two companies is high, and the efficiency of individual years in sub-stages is low. In the R D stage of technical standards, the average value of Huawei"s efficiency is lower than the average value of ZTE"s efficiency; in the transformation stage of standards, the average value of Huawei"s efficiency is higher than the average value of ZTE"s efficiency. Finally, corresponding countermeasures and suggestions are put forward for the problems in the process of enterprise standardization reflected in the research results.
