概要	This paper examines the relationship of offshoring with productivity, based on the original survey data of Japanese firms. Productivity gains were found in the firms offshoring both manufacturing and service tasks, but not in the firms offshoring only either manufacturing or service tasks. This paper also finds that firms offshoring to various destinations tend to be more productive than non-offshoring firms. These results suggest that the level of firms' engagement in offshoring is more important for productivity than whether or not firms engage in offshoring.
