摘要
首先测算了1979-2012年中国的全要素生产率,然后运用改进后的Lichtenberg和Pottelsberghe方法核算出通过服务进口渠道获得的国际R&D资本存量,接着运用基于时间序列数据的GMM、协整模型及VEC模型进行实证研究。得出结论:来自服务进口渠道的国际R&D溢出对中国全要素生产率的提高具有积极的促进作用,但国内重要经济条件是影响该溢出效应发挥的重要门限因素;国际R&D溢出与TFP的短期偏离被系统以较快速度调整至长期均衡状态。
First,this paper estimates ChinaPs total factor productivity from 1979 to 2012,and then calculates international RN-D capital stock from the channel of service import by using the improved method of Lichtenberg and Pottelsberghe, and makes a empirical study by using the models of GMM,co-integration and VEC based on the time series data. The conclusion are as follows:international R^D spillover from service import channels has a positive role in promoting TFP of China,but is affected by some main domestic economic conditions as important threshold factors^short-term deviation between international R^D spillover and TFP is speedily adjusted to the state of equilibrium in long-term.
