From Shenzhen to Cupertino: A Profit-Gradient Analysis of Apples Global Supply Chain

This study provides an in-depth analysis of profit distribution within Apple's iPhone global value chain (GVC), integrating data from Apple's Form 10-K filings, teardown cost studies by TechInsights and Counterpoint, UN Comtrade HS 8517 trade statistics, regional statistical yearbooks (Shenzhen and Zhengzhou), Indian PLFS wage data, and the Santa Clara County Economic Outlook. This study develops a sophisticated value-added model: =RMWO, to allocate unit profits among component suppliers in Shenzhen, assembly centres in Zhengzhou and Chennai, and the Cupertino headquarters. Results show that component manufacturers retain approximately 5% of the unit profit, assemblers retain approximately 15%, and Cupertino maintains over 60%. GIS heat maps and Sankey diagrams vividly illustrate the dramatic surge in earnings at the headquarters node. This study traces this gradient to Silicon Valley's agglomeration economies, intellectual property rent extraction, and strategic transfer pricing. Finally, this study simulated three policy interventions a regional R&D tax credit, a workforce skill upgrading program, and an OECD Pillar 2 minimum tax rateto examine how up to $3.4 billion could be reallocated without undermining Apples incentives to innovate. These findings contribute to the debate on equitable upgrading of digital global value chains.
