Economic globalization has catalyzed the emergence and development of global supply chains, concurrently engendering pervasive labor problems. We have conducted case studies on two major consumer electronics multinationals-American Apple Inc. and South Korea's Samsung Group, comparing and analyzing the labor problems in their respective supply chains under different governance models, namely "vertical disintegration" and "vertical integration", and their engagements in corporate social responsibility initiatives. By doing so, we have revealed the limitations of the corporate social responsibility practices implemented by the Western society in the global supply chains that they dominate. We found that although this initiative has certain positive effects on alleviating labor problems in global supply chains, lead firms of the supply chains in practice refuse to bear the costs of raising labor standards, but instead continuously compress the profit margins of suppliers, especially those in labor-intensive sectors, leading to the ineffectiveness of the collaborative governance model of corporate social responsibility in addressing labor problems in global supply chains. We contend that a comprehensive resolution of labor problems should not be established based on sacrificing the developmental rights of developing countries. Instead, it necessitates the concerted efforts of various stakeholders in the global production networks, especially enforcing the direct economic obligations of multinational capitals for resolving labor problems.
