市场开放、网络生产、技术提升与价值链增值

摘要

This paper sets up an endogenous growth model including open economy situation,analyzes the two technology upgrading mechanisms of open market to R&D and network production,also the value chain appreciation effect brought by the division within product chains and undertaking outsourcing approaches. We find that there is positive effect of the tech-nology upgrading brought by R&D and network production on value chain appreciation based on sample data in China.When compared with the two mechanisms and approaches,the result shows that the effect of R&D mechanism is not sig-nificant;the effect of network production mechanism is different;the technology upgrading and value chain appreciation effect of division within product chains are more obvious than the effect of undertaking outsourcing approach.%通过构建包含开放经济情形的内生增长模型，分析市场开放引起自主研发加大和网络生产两种技术提升传导机制，以及探讨产品内分工与承接外包两种参与途径带来的价值链增值效应。运用中国样本数据验证表明，在市场开放作用下，研发机制引起的技术创新提升和网络生产机制引起的技术溢出提升均有助于实现价值链增值效果；当把市场开放促进价值链增值作用的两种机制和不同网络生产参与途径结合起来比较时发现，研发机制效果不太明显，网络生产机制效果存在差异，产品内分工竞争行为参与途径获得技术外溢提升与价值链增值效果要比承接外包模仿行为参与途径获得的对应效果明显得多。
