摘要
提高出口产品质量是贸易高质量发展的重要内容。本文实证分析了企业中间品进口市场数量变化及其进口市场转换行为对企业出口产品质量的影响。研究结果表明:基于企业个体层面的考察显示,企业中间品进口市场数量的增加,不仅会显著提高企业出口产品质量,而且会显著提高企业的出口产品质量阶梯,主要是通过提高进口中间品质量、降低中间品进口成本两个机制发挥作用,通过改变企业研发投入影响企业出口产品质量的机制是不显著的;从进口市场转换方向来看,无论是从发达国家转向发展中国家,还是从发展中国家转向发达国家,企业调整中间品进口市场都会显著提高其出口产品质量;进一步基于行业层面的考察显示,整个行业中间品进口市场数量的增加会显著提高整个行业的平均出口产品质量。
Improving the quality of exports is an important task for high-quality trade development.This paper empirically analyzes the impact of changes in the number of firms’intermediate import markets and the import market switching on the quality of firms’exports.The results show that at firm level,an increase in the number of firms’intermediate import markets not only significantly improves the quality of firms’exports,but also upgrades the quality ladder,and the main mechanisms are improving the quality of imported intermediate goods and reducing the import cost of intermediate goods.The mechanism of R&D investment is not significant.From the perspective of import market switching,whether switching from developed countries to developing countries,or from developing countries to developed countries,the adjustment of firms’intermediate import markets significantly improves the quality of their exports.Furthermore,at industry level,an increase in the number of intermediate import markets of the industry significantly improves the average quality of exports of the whole industry.
