This note attempts to shed some light on the relationship between the total factor productivity derived from national income accounts and the total input productivity based upon input‐output accounts, especially on a sectoral basis. Since there has been no positive evidence to support a constancy between changes in net and gross output in individual industries, the formulation of a measure of sectoral input productivity change by using the formula of the Divisia index based on input‐output accounts may be valuable in examining possible biases which are associated with a common notion of the total factor productivity. An operational definition of sectoral input productivity change and its relation to sectoral total factor productivity are discussed in the present note, in addition to its empirical application to the Japanese data.
