This paper aims to examine the productivity of the public goods. Theoretically, it is simple to measure the productivity which is defined by the ratio of output to the inputs, the former of which is measured by the value added, GNP, factor incomes, the latter of which are labor, capital and technology. This measurement method is not appropriate for the public goods because of the characteristics of the public goods. This paper attempts to overcome the measurement problem by looking at the multi-inputs and multi-outputs of the public goods for each specific need. For this purpose, we need to clarify the production procedure quantatively and estimate the sectoral productivities of two stage multi-products as well as their synthetic productivity.
