Abstract: This article restarts to calculate the input-output t ables of 122 sectors in 2002 and get the input-output tables of 15 sectors. Thenwe calculate the direct consumption coefficient, Leontief inverse matrix, direc t index of forward linkage and backward linkage, effect coefficient and sense (d egree) coefficient, and output requirement coefficient of all sectors. We analyz e the correlation between Chinese insurance industry and other industries, and g ive some suggestions on accelerating the development of Chinese insurance indust ry. Key words:Input-output; Linkage; Effect; Sense
