基于天津、河南、四川三省市高校科研人员调查数据，论文运用多元回归模型分析产业研究对学术研究的影响。研究发现，横向课题数量对纵向课题数量的影响具有“倒U形”特征，横向课题数量对获得国家级课题没有显著影响。科学地位和组织等级未能显著提升横向课题数量对纵向课题数量和质量的影响。这些经验发现意味着产业研究对学术研究的数量维度具有较多积极效应，但对学术研究的质量维度没有产生显著影响。

Based on the survey data of university teaching and research personnel in Tianjin, Henan, and Sichuan, multiple regression models were used to analyze the impact of industry research on the quantity and quality of academic research. The study find that the influence of the number of industry research projects on the number of academic research projects has an “inverted U ” feature, and the number of industry research projects has no significant effect on obtaining national-level academic research projects. The scientific status and organizational status fail to effectively increase the impact of the number of industry research projects on the quantity and quality of academic research projects. These empirical findings mean that industry research has positive effects on the quantitative dimension of academic research, but has no impact on the quality dimension of academic research.
