Abstract: With the trend of economic globalization, offshore service outsourcing is developing rapidly and its related Corporate Social Responsibility (CSR) issues emerge as a result. However, so far, the related research findings are limited. This study based on the CSR theory of stakeholders and the special characteristics of international service outsourcing, discusses the related CSR issues such as the unemployment problem of outsourcer country, the unfair employment problem of recipient country, etc. In the end, it proposes some corresponding countermeasures to solve these problems, such as: firms of offshore service outsourcing should refer to the international standards of social responsibility such as UN Global Compact, OECD Guidelines for Multinational Enterprises and ISO26000, etc., to establish a proper code of ethics within the organization, consult with the host country’s stakeholders to understand their concerns of CSR issues impacting on their benefits, try best to reduce the related job losses and protect the interests of employees by training and education to improve their skills and strengthen communication channels with the stakeholders like the government, communities, suppliers and employees, etc., so as to increase their awareness of CSR issues and take measures to resolve these issues. And the administrative authority of the government should play an import role in the creation of a capable or proficient supervision on the CSR issue of offshore service outsourcing, etc.
