区域间贸易与收入不平等转移

Interregional Trade and The Transfer of Income Inequality

本文以中国30个省(自治区、直辖市)(除港澳台及西藏外)为研究对象,利用扩展的中国多区域投入产出模型,测算了各地区的不平等足迹,考察2010年由于区域间贸易所引起的地区劳动力收入不平等转移状况,识别出产生不平等的关键地区。结果表明,省份之间通过区域间贸易,互相提供支持,使得不平等伴随着产品和服务的转移而转移;从消费角度考虑,在中国30个省(自治区、直辖市)中,区域间贸易使22个省份的本地区收入不平等程度降低,但也加剧了8个省份的本地区收入不平等程度。因此,各省在缩小本地区的收入差距时,需将区域间贸易纳入政策考虑的范围,以期更为有效地缩小本地区的收入差距。

Taking Chinese 30-province inequality as an example,we use the extended Chinese multi-regional input-output model to estimate inequality footprint of every province,investigate the transfer of income inequality of employment resulting from regional trade,and identify key provinces of income inequality.The results show that provinces provide mutual supporting to each other through interregional trade and thus outsourcing inequality due to the imports of goods and services.From the consumption perspective,interregional trade leads to the decline of income inequality of 22 provinces and the increase of that of eight provinces.In order to narrow income gap effectively among regions,policy-makers need to take the interregional trade into account.
