本文运用协整分析和格兰杰因果检验法对天津市对外贸易与产业结构的关系进行了分析。结果表明,对外贸易对第二、三产业有促进作用,与第一产业的关系不密切;对外贸易与第二产业互为因果关系,而第三产业对对外贸易具有单向因果关系;长期来看,对外贸易对第三产业的促进作用大于第二产业。 This article uses cointegration analysis and Granger causality test to analyze the relationship between Tianjin’s foreign trade and industrial structure. The results show that foreign trade has a positive effect on the secondary and tertiary industries, and the relationship between the secondary industry and the primary industry is not very close. The external trade and the secondary industry are causal relations with each other, while the tertiary industry has one-way causal relationship with the foreign trade. See, the promotion of foreign trade on the tertiary industry is greater than the secondary industry.
