The Estimation of the Number of Employed Person Related to Agriculture in Agribusiness

Agricultural product industry is related with other industries, input industries(backward) in agriculture and post-farm gate industries(forward). We call agriculture-related industry a agribusiness. When we develop manpower in agriculture we should consider not only the number of employed person in agriculture also that related to agriculture in agribusiness. We can use the number of employed person in agriculture by using agricultural statistic books. But we must estimate the number of employed person related to agriculture in agribusiness. The objectives of this study was to suggest the estimation method and to estimate the number of employed person related to agriculture in agribusiness by using Input-Output Tables. The number of employed person in 「Wholesale and retail trade」 and 「Transport and storage」 sector is contained in input industries in agriculture, but the number of employed person in 「Wholesale and retail trade」 and 「Transport and storage」 sector is not contained in post-farm gate industries. (Total intermediate input). The method of estimating the number of employed person in i input industries in agriculture should be (Value of input from i industry to agriculture)/(Gross Domestic Output of i input industries)×(the number of employed person of i input industries). The method of estimating the number of employed person in j post-farm gate industries, in case of general industry that 「Wholesale and retail trade」 and 「Transport and storage」 is excluded in total industry, should be (input of agriculture to j industry)/(Total intermediate input of j industry except 「Wholesale and retail trade」 and 「Transport and storage」)×(the number of employed person in j industry) and in case of 「Transport and storage」 should be (input of 「Wholesale and retail trade」 and 「Transport and storage」 to j industry)/(Gross Domestic Output of 「Wholesale and retail trade」 and 「Transport and storage」)×(input of agriculture to j industry)/(Total intermediate input of j industry - 「Wholesale and retail trade」 and 「Transport and storage」)×(the number of employed person in 「Wholesale and retail trade」 and 「Transport and storage」). The number of employed person related to agriculture in agribusiness was 355,484, that in input industry of agriculture was 101,390, that in post-farm gate industry was 254,094.
