基于工具变量法分析科研人员素养对科研创新产出纯技术效率的影响

【目的】研究科研人员科研素养对其科研创新的投入产出纯技术效率的影响,找出提升科研产出的途径。【方法】利用新疆农业科学院的178名科研人员作为样本,使用工具变量,结合两阶段最小二乘法与DEA-tobit模型对科研人员科研素养对创新投入产出纯技术效率的影响机理和路径研究并验证。【结果】科研素养,以及其包含科研修养、个人能力和科研基础都显著的影响科研创新投入产出的纯技术效率。当加入年龄、科研平台、第一学历等控制变量之后,科研修养的影响发生了不合常理的变化;当使用两阶段最小二乘法处理科研修养之后,发现个人能力、科研基础直接正向影响科研纯技术效率。【结论】研人员的科研素养中,科研基础、个人能力是直接影响,科研修养是间接影响,即科研素养对科研人员的纯技术效率影响是一个多路径的影响机制。

The Impact of Scientific Research Literacy on the Pure Technical Efficiency of Scientific Research Innovation Output Based on the Instrumental Variable

【Objective】 By using 178 scientific researchers of Xinjiang Academy of Agricultural Sciences as a sample, this project aims to study the influence of scientific research literacy on the pure technical efficiency of scientific research innovation input and output in the hope of find out the way to improve the scientific research output under the condition of limited scientific research resources. 【Method】In the process of research, the mechanism and path of the influence of scientific research literacy on the pure technical efficiency of innovation input and output were studied and verified by using instrumental variables, combined with two-stage least square method and DEA-tobit model. 【Results】First of all, scientific research literacy,, including scientific research accomplishment, personal ability and scientific research foundation, has a significant impact on the pure technical efficiency of scientific research innovation input and output. Secondly, when controlling variables such as age, scientific research platform and first degree were added, the influence of scientific research accomplishment changed irrationally. Thirdly, when the two-stage least squares method was used to deal with scientific accomplishment, personal ability and scientific research foundation directly affected the pure technical efficiency of scientific research, while scientific research accomplishment was needed to improve efficiency through scientific research platform, age and first education background. 【Conclusion】The above results showed that to improve the efficiency of scientific research output, raise scientific research literacy, and how to utilize the scientific research quality of existing research personnel become equally important issues
