Local Procurement and Value Chain Upgrading of Offshore Subsidiaries in China

本研究整合子公司發展架構和微笑曲線邏輯，利用2008年至2018年在陸台商的營運資料，驗證其享有採購自主權與於研發與市場行銷的價值鏈提升。本研究結果說明，在陸台商子公司在研發與市場行銷的價值鏈升級上存在正向互動關係，同時肯定採購授權與當地採購程度有其價值鏈升級的積極效果。本研究根據子公司發展的分析架構，歸納總部授權、當地資源條件和子公司主動作為等之實證結果，顯示在陸台商透過研發與市場行銷的價值鏈升級強化其在地主國的競爭優勢。本研究成果提供子公司發展過程的新內涵，重新審視跨國企業的去全球化價值鏈配置策略。

This study integrates the offshore subsidiary (OS) development (OSD) and smile curve paradigms to examine the impact of local procurement on OSs' functional upgrading of value chains (VCs) in China. Based on an offshore subsidiary development framework with headquarters-driven, internal subsidiary-driven, and host economy-driven, we draw on Taiwan-based subsidiaries operating in China from 2008 to 2018 to examine the relationships among value-chain functions, including technological enhancements (TE), marketing operations (MO), procurement mandates, and principal OSD determinants. In sum, the empirical results indicate that Taiwan-based OSs are able to strengthen their competitive advantage in China by engaging in persistent value creation through upgrading both TE and MO. In this study, some insights shed light on subsidiary development processes for multinational enterprises to revisit their strategies for deglobalization of VC configurations.
