This study measures productivity differences in the manufacturing sector among prefectures in Japan by using a two-digit industry and the prefectural level data of the Census of Manufacturers. The author approaches this theme by shift-share analysis as proposed by Esteban. The outcome of the analysis showed that a higher weight in the “productivity differential component” than the “industry structure component” of regions is a major factor for interregional differences in labor productivity of total manufacturing. Furthermore, the author observed the two-digit industry and prefecture level data, and analyzed the effects of regional specialization in a specific two-digit industry on productivity in the shift-share analysis framework. Industry specialization was shown to have different effects on labor productivity, depending on the type of industry. This outcome provides several implications and viewpoints for policies of regional economic development.
