The effects of geographical and business proximity on affiliates' R&D investment: a proximity theory perspective

Purpose - This study aims to examine the impact of geographical and business proximity between parent companies and affiliates on R&D investments in business groups. Furthermore, it compares the moderating effect of value chain participants' bargaining power and the performance-aspiration gap. Design/methodology/approach - This study uses data from 411 Chinese private manufacturing listed firms affiliated with business groups. This paper conducts regression analysis using Stata 16.0 software. Additionally, this paper employs combined random effects regression models, the 2SLS method and GMM method. Findings - Geographical distance between focal affiliates and parent companies is negatively related to focal affiliates' R&D. The higher the business proximity between focal affiliates and parent companies, the more R&D investments are made. Further research shows that with stronger bargaining power and a wider performance-aspiration gap, the negative relationship between geographical distance and R&D investment weakens. Originality/value - This study contributes to the R&D investment literature by offering a novel perspective on why proximity influences affiliates' R&D investments in Chinese business groups. This study enriches the proximity theory by introducing business proximity as a new dimension into the framework. Furthermore, this study highlights the boundary conditions of the proximity theory by ascertaining the moderating effects of bargaining power and the performance-aspiration gap.
