国产机器人企业研发效率评价及影响因素研究

基于国内机器人行业发展现状，利用超效率DEA与Malmquist指数相结合的评价方法以及Tobit回归模型，对我国机器人行业14家上市企业的研发创新效率及影响因素进行实证研究。结果发现：国产机器人R&D效率呈现上升趋势，技术进步突出，政策效果明显，但还存在较大提升空间；研发投入和资本密集度对R&D效率没有显著影响，企业经营规模和融资能力与R&D效率显著正相关。最后，结合研究结果，从营造创新环境、制定行业标准、整合产业链以及转型招商模式等方面提出了政策建议。

Analysis on R&D Efficiency of Domestic Robot Enterprises and Related Factors in China

It empirically studies on the innovation efficiency and influencing factors of 14 Listed Companies in domestic robot industry, with the method of combining super efficiency DEA and Malmquist index and Tobit regression model. It finds out that R&D efficiency of domestic robots show an upward trend, technological progress is very prominent and policy effect is obvious, but there is still much room for improvement; R&D investment and capital intensity never have any significant effect on R&D efficiency, and the scale of business and the ability of financing have significant positive correlation with R&D efficiency. Finally, according to the research results, this paper puts forward some policy suggestions on the development of industry standards, the integration of industrial chain and the transformation of investment model.
