【摘要】 随着人口红利的逐渐消失和用工成本的不断攀升,工业机器人在经济社会发展中的作用越来越重要。基于2013—2017年39家工业机器人上市公司面板数据,DEA-Malmquist全要素生产率及其分解结果显示:我国工业机器人上市公司Malmquist指数及技术进步指数大部分年份均小于1,且全要素生产率的下降主要是由于技术进步的降低。进一步的分类研究显示,主营业务为中游机器人本体和下游系统集成的公司综合技术效率平均值高于主营业务为上游核心零部件的公司。同时,综合技术效率、纯技术效率和规模指数最大值均出现在下游系统集成类公司。更多还原

【Abstract】 With the faded demographic dividend of population and the rising labor costs, industrial robots play an increasingly important role in economic and social development. Based on panel data of 39 industrial robots listed companies from 2013 to 2017, DEA-Malmquist total factor productivity and its decomposition results show that Malmquist index and technological progress index of industrial robots listed companies in China are all less than 1 in some years, and the decline of total factor productivity is mainly due to the decline of technological progress. Studies of further classification show that the average integrated technical efficiency of the companies, whose main business is the integration of the middle-range robot ontology and the downstream system, is higher than that of the companies whose main business is the upstream robot ontology. At the same time, the maximum values of comprehensive technical efficiency, pure technical efficiency and scale index appear in the downstream companies of system integration.更多还原
