企业创新能力及其影响因素研究——基于R的实证分析

Research on Enterprise Innovation Ability and Its Influencing Factors—Empirical Analysis Based on R

近年来,技术创新的重要性愈发突出,创新不仅是一个企业的灵魂,更是一个国家经济发展的重要力量。文章基于中国沪深A股上市公司2017~2021年31家企业的平衡面板数据进行分析,运用数据包络模型计算企业创新效率并分析其分部规律和影响因素。研究结果表明:企业创新效率整体处于较低水平但波动上升,其中国有企业创新效率整体高于民营企业;在外部影响因素方面,高质量外部审计和高区域经济发展水平分别从纯技术效率和规模效率两方面推动企业创新效率。该结论为现阶段提升企业技术创新效率提供了思路,并以此对提升国家整体创新水平提供了相关的建议。

In recent years, the importance of technological innovation has become increasingly prominent. Innovation is not only the soul of an enterprise, but also an important force in the economic development of a country. Based on the balanced panel data of 31 A-share listed companies from 2017 to 2021, this paper uses the data envelopment model to calculate the innovation efficiency of enterprises and analyze its division rules as well as influencing factor. The results show that the overall innovation efficiency of enterprises is at a low level but fluctuates. Moreover, the innovation efficiency of state-owned enterprises is higher than that of private enterprises. In terms of external influencing factors, high level of external audit quality and regional economic development promote enterprise innovation efficiency from pure technical efficiency and scale efficiency respectively. This conclusion provides ideas for improving the technological innovation efficiency of enterprises as well as the overall innovation level of our country at this stage.
