本研究以上海为例采用回归分析模型、基于因子的协整、Granger因果检验及脉冲响应函数,对技术学习通道与研发产业的关系进行了定量研究,结果发现:(1)在技术学习通道的四个组成部分中,无论是传统信息流还是新兴网络信息流对上海研发产业的贡献都小于人流和物流;(2)通过协整检验和与Granger因果检验发现.上海市研发产业与技术学习通道存在长期的均衡关系,技术学习通道在较短时期内是研发产业的Granger原因,而研发产业也在短期对技术学习通道具有一定的推动作用,二者具有一定的良性互动;(3)运用脉冲响应函数得到的结论与Granger因果及二者理论机制分析相一致,技术学习通道对自身的作用一直大于研发产业对技术学习通道的影响,并且技术学习通道对研发产业的作用在稍长的时间内一直大于研发产业对自身的作用。
The relationship between the technological learning channel and R&D industry is conducted a quantitative study used regression analysis model, based on factors Co integration, Granger causality test and impulse response function, taking Shanghai as an example. The study finds that in the four components of technological learning channel, both traditional information flows and emerging network information flows of the Shanghai R&D industry are less than the contribution of person mobility and goods flows. Equilibrium relationship exists between Shanghai's R&D industry and technological learning channel long-term through Co integration test and Granger causality test. Technological learning channel is R&D industry Granger cause in a relatively short period and R&D industry plays a certain role in the construction of technical learning channel in the shorter term. Both have some positive interaction. Conclusion shows that using the pulse response function is consistent with Granger causality test and theory mechanism analysis. The impact of the technical study channel on their own is more than on R&D industry all the time, and the impact of the technical study channel on their own is larger than that on R&D industry in the longer period.
