摘 要: 本文区分了国有企业和非国有企业就业对经济增长的贡献,并在增强省际数据横向可比性的基础上,应用DEA方法测算了1980—2004年各省区的TFP、技术效率和技术进步指数。我们发现,我国的TFP总体上是增长的,主要是由于技术进步引起的。接着,我们应用非线性广义最小二乘法,探讨了省际技术进步的空间扩散问题,结果证实我国存在着从北京、上海、广东向其他省区的技术扩散,而且这种扩散依赖于空间距离;技术扩散地区的人力资本投资、产业结构调整和专业化不仅能够带动自身的技术进步,而且能够促进其他省区的技术进步。 We first differentiate the contribution of SOE and NSOE' s employment, build up the comparableness between the provincial data, and then measure the TFP, efficiency and technical change indexes by DEA. We find that China' s TFP is promoted mainly by the technology progress after the economic transition. While using the Nonlinear EGLS, we find a spatial diffusion mechanism from Beijing, Shanghai and Guangdong to other provinces, which depends on the spatial distance. The technology progress in advanced areas by investment in human resource, specialization and industrial structure adjustment can be diffused and promote the technology progress in other provinces.
