摘要
技术密集型产品进口对一国经济增长和出口贸易发展作用巨大。现有文献表明提升知识产权保护水平能促进中等收入水平国家技术密集产品进口,但少有对进口增长途径和结构分解的研究。基于企业异质性理论,利用2002~2017年HS6分位贸易数据,在测算了中国技术密集型产品进口二元边际的基础上,实证检验了知识产权保护对其产生的影响。结果表明:提升知识产权保护水平对中国技术密集型产品进口的促进作用源于扩展边际的增长,而非集约边际;分国别来看,知识产权保护会显著促进中国自新兴经济体、发展中国家、发达国家技术密集型产品的进口,这种促进效果依次减弱;分产品种类来看,知识产权保护对各类技术密集型产品进口二元边际的影响存在着差异。
The import of technology-intensive products plays an important role in a country’s economic growth and export trade. Existing literature shows that improving the level of intellectual property protection can promote the import of technology-intensive products in middle-income countries,but there is a lack of research on the growth path and structural decomposition of imports. Based on the theory of enterprise heterogeneity,with HS 6-digit trade data from 2002 to 2017,this paper calculates the binary marginal value of China’s technology-intensive product imports,and tests the impact of intellectual property protection on it. The results show that the promotion of intellectual property rights on China’s import of technology-intensive products comes from the growth of extensive margin rather than intensive margin. By country,IPR protection will significantly promote China’s import of technology-intensive products from emerging economies,developing countries and developed countries,and the promotion effect will decrease in turn. In terms of product categories,the influence of intellectual property protection on the import binary margin of various technology-intensive products is different.
