• Strategic alignment of the HR function across borders is a central pattern: Strategic Human Resource Management (SHRM) and Strategic International Human Resource Management (SIHRM) frameworks argue for integrating HRM/HRD with corporate strategy in multinational firms. Supported by SIHRM integrative models [3][8], macro SHRM debates [10], and HRD strategy emergence [5].

• Devolvement of HRD to line managers and recognition of HRD as a strategic, actor-driven function. Studies emphasize devolved training responsibilities, line-manager involvement, and the strategic roles of HRD in shaping practice [19][20][16].

• Globalization and cross-cultural HRM: convergence vs divergence; culture shapes HR policies, with Chinese HRM contexts and comparative theory. The literature maps cultural constraints in management theories and cross-national HR practices, highlighting convergence/divergence dynamics [1][4][2][7][14].

• HRD theory foundations and framing: HRD matured as a field within HRM, with integrative and theoretical approaches. Foundational works discuss HRD emergence, common HRD theories, and strategic HRD roles shaping research and practice [5][11][20][16].

• Strategic linkages between training policy, HRD/HRM, and organizational goals: policy-practice alignment and performance-focused HRD are recurrent concerns, emphasizing how training and HRD contribute to business outcomes [12][9][10].
