产品模块化对中国航空高端制造业集群升级的影响:一个有调节的中介效应模型

Impact of Product Modularity on Upgrading of High-end Aviation Manufacturing Industry Cluster in China:A Moderated Mediation Effect Model

以中国航空高端制造业集群为研究对象,探讨了产品模块化、集群创新与集群升级之间的关系,分析了环境不确定性在其中的调节作用,构建了一个有调节的中介效应模型,以厘清航空高端制造业集群模块化升级的机理。研究结果表明:产品模块化不仅对集群升级有直接影响,而且通过集群创新对集群升级产生间接影响,即集群创新在产品模块化与集群升级之间发挥部分中介作用;环境不确定性对集群创新的中介效应具有调节作用,具体而言,环境动态性负向调节集群创新与集群升级的关系,环境竞争性正向调节集群开发性创新与集群升级的关系,但对集群探索性创新与集群升级间关系的调节作用不显著。据此,提出了促进中国航空高端制造业集群升级的策略。

Taking high-end aviation manufacturing industry cluster as the research object,this paper discusses the relationships among product modularity,cluster innovation and cluster upgrade,and builds a moderated mediation effect model to clarify the mechanism of modular upgrade of high-end manufacturing aviation cluster.The results show as follows：product modularity not only has direct impacts on cluster upgrade,but also has indirect effects on it by cluster innovation,that is,cluster innovation plays a partial intermediary role between product modularity and cluster upgrade;environmental uncertainty has a regulatory role on the mediation effects of cluster innovation,specifically,environmental dynamics negatively regulates the relationship between cluster innovation and cluster upgrade,and environmental competition positively regulates the relationship between cluster exploitative innovation and cluster upgrade,but has no significant regulatory role on the relationship between cluster exploratory innovation and cluster upgrade.Finally,it proposes some strategies to promote the upgrade of China＇s high-end aviation manufacturing clusters.
