Abstract (in Japanese) (See Japanese page) 
(in English) This study explores the growth dynamics of India’s automotive supplier industry, focusing on the strategic role of Maruti Suzuki India. Using financial data from 2014 and a machine learning regression model (XGBoost) combined with SHAP (SHapley Additive exPlanations), we quantitatively identify the factors driving market capital growth among 65 global automobile manufacturers. Our analysis highlights that inventory efficiency and absolute sales volume were more influential than sales growth rate in determining market valuation. Among the top performers, RICO AUTO, a key supplier to MARUTI, exhibited the highest market capital growth, demonstrating the ripple effects of MARUTI’s supplier development strategy. As a joint venture with the Indian government, in the beginning, MARUTI expanded its market share in passenger vehicles and systematically cultivated a robust local supply chain. This study argues that MARUTI’s influence was pivotal in shaping India’s automotive supplier ecosystem, offering important lessons for strategic joint ventures in emerging economies.
