贸易政策对中国区域工资变动的影响:基于关税与汇率的视角The Impact of Trade Policies on Regional Wage Changes in China:From Tariffs and Exchange Rates Perspectives
潘文卿,陈佳楹
摘要(Abstract):
本文主要探讨关税和汇率政策的实施对中国区域工资水平及分布的影响。本文通过构建中国1997—2016年的省级面板数据模型,将两个新经济地理因素变量与两类贸易政策变量相关联进行实证分析。研究发现,关税降低和实际汇率升值有助于提升中国各省区的工资水平;同时,关税下降还会进一步扩大东部沿海地区与内陆地区间的工资差异,但汇率变动则不会带来异质性的影响。虽然资源大省的工资水平比非资源大省低,但关税与汇率变动的影响均不会因省区是否为资源大省而产生显著差异。另外,本文也考察了东部地区外部性的影响,发现当控制了距海外市场的距离后,东部地区的工资水平并不会比其他地区有着额外的提升;通过加入WTO以及人民币定价机制改革两项自然实验,发现在中国加入WTO后关税变动的影响力度更大,汇率变动也在汇率定价机制改革后对距海外市场较近省区工资水平的影响更大一些。
