摘要
本文利用随机前沿生产函数测算了中国高技术产业的研发效率,并考察了企业规模、市场结构和所有权结构等因素对研发效率的影响。主要研究结论是:中国高技术产业的研发效率整体偏低,但呈现稳步上升状态,行业间效率差异有逐步缩小趋势。企业规模和市场竞争程度与研发效率之间存在着显著的正相关关系,外商投资企业和国有企业比重对研发效率也有正向影响,但外商投资企业对研发效率的贡献程度更高。
Using the stochastic frontier analysis technique, this paper calculates R&D efficiency of Chinese high-tech industries. Following this work, the paper investigates the influence of firm size, market structure and ownership structure on R&D efficiency. The main conclusions are introduced as follows. Though R&D efficiency of Chinese high-tech industries is low, it's growing with steady steps, At the same time,the difference of R&D efficiency among industries is reducing gradually. R&D efficiency is positively related with finn size and market competition. Foreign investment enterprises play more important role in enhancing R&D efficiency than state owned enterprises.
