加入世贸组织后中国省际贸易成本测度、效应及决定因素

The Measurement,Effects and Determinants of Chinese Interprovincial Trade Costs after Accession to the WTO

本文利用Novy(2013)模型,测度中国加入世贸组织后省际贸易成本、效应及其决定因素,结果表明:省际贸易成本有所下降,但降幅较小;与中国国际贸易成本及外国省际贸易成本相比,中国省际贸易成本所反映的国内市场一体化水平均较低;分产业来看,工业的省际贸易成本远低于农业和服务业;经济增长和省际贸易成本下降对国内贸易增长都具有重要促进作用,经济增长对国内贸易的贡献超过了贸易成本下降的贡献度;交通基础设施对降低省际贸易成本的作用最为显著。

Using Novy（2003） model,this paper measures the interprovincial trade costs, its effects and determinants in China after accession to the WTO. The result shows that the interprovincial trade costs decline slightly; compared with Chinese foreign trade costs and other countries＇ interprovincial trade costs,domestic market integrations indicated by domestic interprovincial trade costs are slow; the interprovincial trade costs of industry are much lower than that of agriculture and service; both economic growth and the decline of interprovincial trade costs play an important role in domestic trade increase,but the contribution of the former exceeds the latter; traffic infrastructure is the most important factor in reducing trade cost.
