基于多水平结构方程模型的准入机制与宇航元器件销量关系研究

Research on Relationship of Access Mechanism and Sales-volume of Aerospace Components by Multi-level Structural Equation Modeling

通过多水平结构方程模型研究宇航元器件市场准入机制对销量的影响机理。研究表明,宇航元器件市场准入机制对销量有显著正向影响,其直接效应的解释率达到了43%;宇航元器件市场准入机制对市场需求与销量之间的关系具有调节作用;市场竞争和企业经营因素分别在宇航元器件市场准入机制与销量的关系中起中介作用,且二者的作用效果相反。

In this paper, the influence mechanism of market access mechanism on sales volume of aerospace components was studied by multi level structural equation model. The research shows that the market ac cess mechanism has a significant positive effect on sales volume and its direct effect has an explanation rate of 43 %. The market access mechanism has moderation effect in the relationship between the market de mand and the sales volume. Market competition factor and enterprise operation factor both have mediation effects in the relationship between the market access mechanism and the sales volume, but their effects are opposite. Some phenomena found by the research , are enlightening for the enterprise strategy of aerospace components companies.
