From a macroeconomic perspective, investing in infrastructure is a “twofer”: It strengthens productivity and competitiveness in the long run and boosts demand and creates jobs in the short run. According to the Congressional Budget Office, infrastructure spending is one of the most cost-effective forms of federal government spending in terms of the number of jobs created per dollar allocated.
从宏观经济学角度讲，基础设施投资“事半功倍”：它能在长期强化生产率和竞争力，在短期创造就业岗位。根据国会预算办公室的数据，从每一美元所创造的的就业数量衡量，基础设施支出是联邦政府性价比最高的支出形式。
