“互联网+”战略下信息技术服务业创新效率评价研究——以北京、上海、广东三地为例

Evaluation of innovation efficiency of information technology service industry under the

摘要:

本文选取2013-2018年北京、上海、广东三地的信息技术服务业上市企业为研究样本,以三阶段DEA模型为主要研究方法,对信息技术服务企业的创新效率进行测度与评价。实证结果表明：政府补贴、股权集中度以及企业的国有产权性质会增加创新投入冗余,而企业规模和地区经济发展水平对创新投入冗余有抑制作用；信息技术服务企业的创新综合效率值较低,其主要原因在于纯技术效率低,资源投入结构不合理导致资源配置与转换效率低,内部管理有待加强；进一步根据纯技术效率和规模效率将样本企业划分为5种类型。以此提出提高信息技术服务企业创新效率的建议。

Abstract:

This paper selects the listed information technology service enterprises in Beijing, Shanghai and Guangdong from 2013 to 2018 as the research samples, and takes the Three-stage DEA model as the main research method to measure and evaluate the innovation efficiency of information technology service enterprises. The empirical results show that: government subsidies, ownership concentration and the nature of state-owned property rights of enterprises will increase the redundancy of innovation input, while the scale of enterprises and the level of regional economic development will inhibit the redundancy of innovation input; the value of innovation comprehensive efficiency of information technology service enterprises is low, which is mainly due to the low efficiency of pure technology and the unreasonable structure of resource input, resulting in the allocation and transformation of resources According to the pure technical efficiency and scale efficiency, the sample enterprises are divided into five types. Finally, this paper puts forward suggestions to improve the innovation efficiency of information technology service enterprises.
