The Effect of R&D on the Technical Efficiency, Technical Progress and Productivity in Chinese Manufacturing Industry: a Malmquist Index-Based Analysis
Author(s): 
Pages: 580-585
Year: Issue:  5
Journal: CHINESE JOURNAL OF MANAGEMENT

Keyword:  R&D制造业Malmquist指数技术效率技术进步;
Abstract: 首先运用基于DEA的Malmquist生产率指数对中国制造业各行业全要素生产率、技术效率和技术进步进行了测算,发现产业的技术密集度越高,技术进步、技术效率和全要素生产率指数增长越高.然后对具有较高R&D密集度的高技术产业,考察各种不同R&D活动的作用,发现企业内部R&D主要通过提高技术进步、公共R&D主要通过推进技术进步对高技术产业要素生产率的提高产生显著影响,外资活动仅对技术效率的增长产生影响,未能产生明显的技术扩散效应.
