A DEA-Malmquist-Based Study of Technical Efficiency in Listed Cloud Computing Firms

当前我国大力发展数字经济，云计算产业作为数字经济的核心基础设施，其技术效率的研究对产业发展和政策制定具有重要参考价值。基于此，本文运用DEA模型对全国不同地区的35家云计算上市企业2016~2021年面板数据进行分析，使用Malmquist指数动态研究我国云计算企业全要素生产率的变化情况，进而从政府和企业两方面对我国云计算产业的发展提供相应建议。研究表明：云计算产业综合技术效率尚未达到有效、综合技术水平仍需提高；云计算产业综合技术效率受制于纯技术效率；技术进步是制约云计算产业全要素生产率提高的主要因素。At present, China vigorously develops the digital economy, and the cloud computing industry, as the core infrastructure of the digital economy, has an important reference value in the study of its technical efficiency for industrial development and policy formulation. Based on this, this paper uses the DEA model to analyze the panel data of 35 cloud computing listed enterprises in different regions of the country from 2016 to 2021, and uses the Malmquist index to dynamically study the changes in the total factor productivity of China’s cloud computing enterprises, which in turn provides corresponding suggestions for the development of China’s cloud computing industry from both the government and the enterprises. The study shows that: the comprehensive technical efficiency of the cloud computing industry has not yet reached the effective level, and comprehensive technical level still needs to be improved; The comprehensive technical efficiency of the cloud computing industry is subject to the pure technical efficiency; Technological progress is the main factor restricting the improvement of total factor productivity in the cloud computing industry.
