中文摘要：

基于居民部门封闭的投入产出模型进行扩展,并将政府部门从最终需求列中转移出来,纳入到生产部门,列入投入产出表的第Ⅰ象限,政府部门所在的行是以货币形式表现的各部门（包括居民部门）的税收支付,政府部门所在的列是政府对各个部门的各种消费品和劳务的消费额,得到了扩展的局部闭投入产出模型,并在此模型的基础上得到了各种乘数。进一步将投资考虑进去得到动态投入产出扩展模型,使得国民经济各个生产部门、居民部门、政府部门成为一个完整的投入产出平衡体。

英文摘要：

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.
