中国地区研发创新的相对效率与全要素生产率增长分解

On the Efficiency and Total Factor Productivity Growth of China's R&D Innovation

以1998～2006年中国大陆30个省级地区的面板数据为基础,应用超越对数随机前沿模型,实证测评了各地区研发创新的相对效率与全要素生产率增长情况。研究显示一段时间内全国整体研发创新技术效率较低,尚有较大的提升空间;各地区研发创新技术效率存在差异,且东部地区高于中、西部;研发创新的全要素生产率与技术进步均有所增长,但增幅减缓;技术进步是全要素生产率增长的主要动力,而技术效率在考察期内并未发生明显变化;全要素生产率增长与技术进步均不存在绝对收敛,但存在条件收敛。

Based on the panel data of China＇s 30 regions during 1998-2006, this study conducts an empirical analysis on the R＆D innovation efficiency by using the stochastic frontier production function. Our results show the whole country＇s R＆D innovation efficiency is low, and still has a large space for improving; the R＆D innovation efficiency is different among different regions, and the east is higher than the middle and west. The total factor productivity and technology progress are growing, but the growth breadth is decreasing; technology progress is the main cause of the growth of total factor productivity, but the efficiency improvement is not obvious; there is not absolute convergence, but there is conditional convergence in the whole country and all regions.
