类似地，2017年上半年，经通胀调整的零售额实现了10%的年化增长 — — 比6.9%的总体GDP增长速度快了大约4.5 % — —这反映了家庭收入的迅速增长和电子商务推动力的日益强大（并且可能被低估 ） 。
Similarly, 10% annualized gains in inflation-adjusted retail sales through mid-2017 – about 45% faster than the 6.9% pace of overall GDP growth – reflect impressive growth in household incomes and the increasingly powerful (and possibly under-reported) impetus of e-commerce.
