消费品关税减让的价格效应与福利分析——来自2017—2019年关税改革的经验证据

The Price and Welfare Effects of China's Consumer Goods Tariff Reduction During 2017-2019

本文检验了2017—2019年消费品关税减让的价格效应和福利影响。结果表明,消费品降税显著降低进口价格和进口成本,促进了进口数量和种类的增加;同时,降税加强了国内市场竞争,降低了国内消费品的价格,提高了居民实际购买力和福利水平。2018年因关税削减引致的进口成本下降约占中国从除美国外其他国家进口消费品总额的1.33%,消费品平均价格同比下降约0.64%。本文为进一步扩大开放、促进消费扩容提质提供了实证支撑。

We investigate the price and welfare effects of China's consumer goods tariff reduction during 2017-2019 and find that the policy has caused large declines in cost to importers,which encourages import quantities and varieties.The tariff reduction also lowered domestic retail prices through pro-competitive effect,which improves the welfare of residents.The reduction in cost to importers amounts to 1.33 percent of total consumer goods imports from countries other than the U.S.during 2018,and the resulting declines in retail prices are 0.64 percent on average.These results provide empirical evidence for expanding opening up and unleashing consumption potential.
