建筑业上市企业科技创新效率及影响因素研究——基于DEA-Tobit模型

Research on Technological Innovation Efficiency and Its Influencing Factors of Listed Construction Enterprises：Based on DEA-Tobit Model

摘要:

本文用DEA方法从静态和动态两个角度对“十三五”期间25个建筑业上市企业科技创新效率进行测算,并采用Tobit回归对科技创新的影响因素进行探究。结果表明：企业科技创新效率的进步得益于技术进步的增长,其退步是受纯技术效率降低的影响；民营和国有企业在科技创新效率上存在差异；企业规模和税收负担对科技创新效率具有促进作用,政府补助对科技创新效率具有抑制作用。基于研究结论,对提高建筑业企业科技创新效率提出对策建议。

Abstract:

The article uses the DEA method to measure the technological innovation efficiency of 25 listed construction companies during the "Thirteenth Five-Year Plan" period from static and dynamic perspectives, and uses Tobit regression to explore the factors that affect the technological innovation of construction enterprises. The research found: the progress of technological innovation efficiency benefits from the increase of technological progress, and its regression is affected by the decrease of pure technical efficiency; private enterprises differ from state-owned enterprises in technological innovation efficiency; the scale of enterprises and tax burdens promote the technological innovation efficiency, and government subsidies have a restraining effect on the technological innovation efficiency. In view of the above conclusions, relevant countermeasures and suggestions are put forward for improving the technological innovation efficiency of construction enterprises.
