Abstract: Abstract: The models are extensions to the input-output model which is closed about the household department, by transferring the government department from the final demand column into the production sector and included in the first quadrant. The line of the government department is tax payments as a form of currency from all sectors (including household sector), and the column of the government department is the government's various consumer goods and services spending .Based on the extended input-output model, we get a variety of multipliers. Further more, investment is to be taken into account and we get dynamic input-output model, making the production departments, household department and government departments as a complete input-output balance body.
