资本积累与研发创新动态融合的实证研究

本文在ADF和PP单位根检验、Johansen协整分析以及约束误差修正模型的实证框架下，对理论界普遍关注的资本积累与研发创新的动态融合问题进行分析，发现两者间的动态融合关系是极为稳健的。更细化的实证考察表明资本积累与研发创新具备显著的短期双向因果反馈效应；但无论以实际产出、物价水平还是进出口总额作为控制变量，资本积累和研发创新之间仅具备长期单向因果联系，从而指明仅以全要素生产率衡量技术进步率的核算方法缺陷，证实了中国依附于资本积累的体现型技术进步的存在合理性。

An Empirical Research on the Dynamic Integration of Capital Accumulation,R&D and Innovation

In the empirical framework of ADF unit root Test,Johansen co-integration and restraint ECM,the issue of the integration of capital accumulation and R&D innovation is researched in this article.We find that the dynamic integration relationship between them is robust.A more detailed empirical study shows that there are significant short-term and two-way feedback effects between them.But when real output,price level or import and export are as control variables,there is only long-term and one-way causal link.S...
