摘要
本文基于地区和产品贸易模型及对中国进口非关税壁垒的测算,探究了降低进口非关税壁垒对中国拓展进口多元化的影响。研究表明:中国进口非关税壁垒主要集中在预制食品、动植物产品、鞋帽与羽毛制品等品类;从加拿大、澳大利亚、泰国、越南等来源地进口的非关税壁垒较高。进口非关税壁垒降低能显著促进中国进口产品来源地和进口产品种类多元化。此外,在拓展进口来源地时,降低进口非关税壁垒对同质品的促进效应大于异质品,对资本品的效应则大于最终品与中间品;对劳动与资源品、初级品的促进效应大于低、中和高技术制造品,且降低于CPTPP成员非关税壁垒比其他经济体对中国拓展进口来源地多元化的促进作用更大。
Based on domestic and product trade models and the estimation of non-tariff barriers to China’s imports,this paper studies the impact of reducing non-tariff barriers to imports on China’s import diversification expansion.The results of the study indicate that non-tariff barriers to China’s imports are mainly concentrated in prepared food,animal and vegetable products,shoes,hats and feather products,etc.;among the different sources of import,non-tariff barriers to China’s imports from Canada,Australia,Thailand and Vietnam are shown to be relatively high.Reducing non-tariff barriers to imports can significantly promote the diversification of China’s import sources,while significantly improving the diversification of China’s import varieties.In addition,by reducing non-tariff barriers to imports to increase the diversification of import sources,the promotional effect on homogeneous and capital products is shown to be greater than that on differentiated,and final and intermediate products respectively;the promotional effect on labour,resources and primary products is greater than that on low-,medium-and high-tech manufactured products.CPTPP members also play a greater role in promoting the diversification of China’s expanding sources of import than other economies.
