这样，未来两年5000亿美元的额外联邦基础设施支出将产生1万亿美元的额外商品和服务产出，创造大约700万人年的额外就业机会，将每年的失业率降低2个百分点。
In that case, the $500 billion of extra federal infrastructure spending over the next two years would produce $1 trillion of extra output of goods and services, generate approximately seven million person-years of extra employment, and push down the unemployment rate by two percentage points in each of those years.
