| 摘 要： | 本文利用数据包络方法(DEA)对我国31个地区2005年科技投入技术效率、技术与规模效率进行总体评价,并利用Tobit回归模型对影响科技投入的无效率因素予以识别。研究表明,我国地区科技投入在效率上存在显著差异,并且不少地区效率低下;科技投入对经济增长贡献总体偏低;技术与规模效率共同有效的地区较少;科技人员和科技经费相对于投入规模而言,其产出效率不高;R&D经费、技术市场成交合同金额是影响科技投入无效率的重要因素。

| Abstract: | This paper implements Data Envelopment Analysis(DEA)to generally evaluate Research ad Development(R & D)inputs of thirty-one Chinese regions in 2005 from technical efficiency,aggregate technical and scale efficiency,and recognize the inefficiency factors of R & D inputs based on Tobit Regression Model.The results show:There are significant differences on efficiency of Chinese regional R & D inputs, with some regions of low efficiency;The contribution of R & D inputs to economic growth is generally low;Minor... |
