地区知识产权保护与中国对“一带一路”沿线国家出口的质量研究

The Study of Regional Intellectual Property Protection and the Quality of China's Export to Countries Along the Belt and Road Route

基于嵌套Logit模型,测算了中国对"一带一路"沿线国家制造业的出口产品质量,利用中国2004—2014年省际面板数据研究了知识产权保护对出口质量的影响。研究发现:在控制了内生性和其他因素的影响后,中国省级知识产权保护强度对中国出口到"一带一路"沿线国家的产品质量有着稳定且正向的影响。分地区估计的结果显示:知识产权保护强度对出口质量的影响呈现省际差异;东部省份、中部省份、"一带一路"重点省份和非重点省份的知识产权保护水平对出口质量的影响显著为正,而西部省份的知识产品保护强度对出口产品质量的影响为负且不显著。

Based on the nested Logit model,this paper investigates the product quality of Chinese export products to countries along the Belt and Road route. Then this paper uses Chinese inter-provincial panel data from 2004 to 2014 to study the impact of intellectual property protection on export quality. The study finds that after controlling the effects of endogenous and other factors,the intensity of provincial intellectual property protection in China has a stable positive impact on China＇s exports to the countries along the Belt and Road route. The results of sub-regional estimation show that the impact of intellectual property protection on export quality presents inter-provincial differences. It is a significantly positive impact that the level of intellectual property protection has on the quality of exports in the eastern provinces,the central provinces,as well as the key and non-key provinces of The Belt and Road Initiative. Whereas the impact of provincial intellectual property protection intensity on export quality is negative and non-significant in western provinces.
