With the deepening of globalization and the accelerating pace of technological innovation, improving enterprise efficiency has become a core concern across industries. Against the backdrop of the digital economy, traditional business models are facing unprecedented challenges, and the digital transformation of enterprise human resource management (HRM) has become a key pathway for adapting to environmental changes and enhancing organizational performance. This dissertation explores the relationships among government policy support, artificial intelligence (AI) technology application, human resource management innovation, human resource training investment, firm efficiency, and economic performance in a high-government-subsidy environment. By constructing an integrated theoretical framework and conducting empirical analysis based on two public archival firm-year datasets of Chinese A-share listed firms, this study examines how internal digital HRM-related capabilities and external policy-resource support jointly influence firm outcomes. The results show that HRM innovation and AI application have significant positive effects on firm efficiency. Government subsidies also have a significant positive effect on firms’ economic performance. In addition, government subsidies significantly moderate the relationship between human resource training investment and economic performance, but the moderating effect is negative, indicating that higher subsidy levels may weaken the marginal contribution of additional training investment to economic performance. Overall, this dissertation suggests that enterprise HRM digital transformation is not only a technological issue or a policy-support issue, but a process shaped by the joint effects of internal capability building and external policy-resource support. The findings provide implications for enterprises seeking to improve digital HRM transformation and for policymakers designing subsidy policies to support enterprise development.
