Research Abstract

Input-Output table has been produced every five years since 1955 it is the comfiled statistical table which is based on Leontief's input-output analysis. Based on this comfiled statistical table, econometric analysis of production structure conducted regularlly. In particular, in case of input-output table following the open static model, production structure is described as input matrix in each production section. It is considered that the input coefficient that is an element of this matrix is a parameter of Leontief type production function. In this study, we tried to analyse the theoretical hypothesis in input-output table by using micro data of Manufacturing Census. After constructing the panel data using this census data, we divided the establishment groups which controlled production items (sixth digit of standard industrial classification) by, (1) continuation, (2) new entry, (3) exit, and estimate labor input coefficient. As a result it became clear that labor input coefficients differ substantially among different business conditions (i.e. continuation, entry and exit) ever within the same industrial classification code. For example, for companies whose greatest production item is same in 1990, coefficient is smallest for companies with exit (3), and the largest for companies with continuation (1). The other industry with digits of industrial classification code shows statistically significant differences, in coefficient values. To improse statistical accuracy of input-output table, it may be advisable to select samples, taking into account of distribution of input coefficients. The labor input coefficients.
