“隐性贸易壁垒非中性”与进口贸易利益

The Non-neutrality of Implicit Trade Barriers and Gains from Imported Intermediates

不同所有制企业所面临的“隐性贸易壁垒”存在明显的差异性,我们将此称为“隐性贸易壁垒非中性”。本文构建理论模型并采用量化分析法系统考察了隐性贸易壁垒的所有制差异对进口贸易利益的影响。研究发现:(1)隐性贸易壁垒的所有制差异降低了社会福利和贸易利益;(2)贸易壁垒下降对民营企业生产率的推动作用更大;(3)国内贸易成本的提高使得企业进口采购比例增加,迫使企业过度依赖中间品进口,也放大了中国的进口贸易利益。

The “implicit trade barriers” faced by enterprises of different ownership are obviously different. Using a quantitative analysis method to systematically we try to investigate the impact of implicit trade barriers on import welfare effects. Our findings are as follows:(1) the difference in implicit trade barriers reduced social welfare and trade benefits;(2) the decline in trade barriers had a greater effect on the productivity of private enterprises;(3) higher domestic trade costs have increased the proportion of firms’ import sourcing, which has forced companies to rely excessively on the imported intermediates and magnified China’s import trade benefits.
