高新技术产业中信息技术企业创新效率评价研究

信息技术企业是我国高新技术产业中的重要组成部分,其创新效率可以有效反映当前高新技术产业的创新活力与创新水平。但目前我国的创新效率较低,创新评价体系不够完善。传统的创新评价方法受到环境变量的影响,对效率的测度仅停留在在产业及区域层面,创新效率评价不全面。本文运用DEA与SFA技术相结合的“三阶段DEA”分析法对我国上市公司中35 家信息技术企业的创新效率进行测度评价。研究表明,一阶段我国信息技术企业普遍处于创新无效率状态,在剔除宏观及微观环境变量的影响后,信息技术企业的创新效率显著提升,发展前景可观。环境因素方面,政府补助、主营业务收入及资产总计与创新资源的投入冗余成正相关,资产利润率及资产负债率与创新资源的投入冗余呈负相关。

Research on Evaluation of Innovation Efficiency of Information Technology Enterprises in High-tech Industry

Information technology enterprises are an important part of China''s high- tech industry. Its innovation efficiency can effectively reflect the innovation vitality and innovation level of current high- tech industries. However, at present, China''s innovation efficiency is low, and the innovation evaluation system is not perfect. The traditional innovation evaluation method is affected by environmental variables. The measurement of efficiency only stays at the industrial and regional level, and the evaluation of innovation efficiency is not comprehensive. This paper uses the "three- stage DEA" analysis method combined with DEA and SFA technology to measure and evaluate the innovation efficiency of 35 information technology enterprises in China''s listed companies. The research shows that in the first stage, China''s information technology enterprises are generally in an inefficient state of innovation. After eliminating the influence of macro and micro environmental variables, the innovation efficiency of information technology enterprises has been significantly improved, and the development prospects are considerable. In terms of environmental factors, government subsidies, main business income and total assets are positively related to the redundancy of investment in innovative resources. Asset profitability and asset- liability ratio are negatively correlated with the input redundancy of innovation resources.
