That is, the multiplier is the multiple by which an initial change in aggregate spending will alter total expenditure after an infinite number of spending cycles. 换句话说，乘数是这样一个系数，用这个系数乘以总支出的最出变动量，可以得到经过无数次支出循环的总支出。
Local government expenditure usually represents only a very small proportion of total expenditure within any community, the lion's share coming from private purses. 在任何社会，地方政府的开支常常只能代表地方总支出的极小部分，而最大部分主要来自私人的口袋。
