在供应商参与新产品开发影响因素研究的基础上，构建影响因素模型，提出了不同类型企业供应商参与新产品开发实施情况的差异，以及驱动因素和使能因素对供应商参与新产品开发实施情况作用程度所存在差异的假设。通过对我国100多家企业的问卷调查和多元回归分析，深入研究了各类影响因素的作用机理。

Based on the research of influencing factors for Supplier Involvement in NPD(SINPD), a model of influencing factors for SINPD is set up. It is proposed that different types of enterprises are different in their SINPD, driving factors and enabling factors also have different effects on their SINPD. Then, the mechanism of influencing factors for SINPD is also validated by questionnaire investigation with a sample of more than 100 firms and by the method of multi-regression analysis.
