现有文献表明，目的地国的知识产权保护是出口的一个重要决定因素。本文利用中国出口企业产品层面的数据和城市层面的IPP统计数据，实证检验了IPP程度对原产地出口产品质量的影响。为了建立因果关系，我们采用工具变量（IV）方法。2008 - 2013年的面板回归结果表明，事实上的IPP有助于出口产品质量升级，并且结果对IPP措施、IV以及不同控制变量组合（如企业和行业水平补贴）的变化具有稳健性。我们的异质性结果表明，IPP的改善有利于资本密集度较低的公司;外资企业相对于内资企业;以及创新密集型行业的公司。IPP对出口产品质量的影响在某些地理区域（即，中西部地区）和贸易模式（即，加工贸易）。此外，我们表明，通过IPP影响产品质量的渠道包括加强R&D投入，新产品开发，并减轻资金限制。
Intellectual property rights protection (IPP) at destination countries is an important determinant of exports, a result shown by the existing literature. This paper empirically examines the effect of the degree of IPP on export product quality at the origins, using firm-product level data from Chinese exporters and city-level statistics of IPP. To establish the causal relationship, we employ an instrumental variable (IV) approach. Our panel regression results from 2008 to 2013 show that the de facto IPP contributes to the export product quality upgrading and the result is robust against variations of IPP measures, IVs, and different combinations of control variables such as the firm and industry level subsidies. Our heterogeneity results indicate that the betterment of IPP favors less capital-intensive firms; foreign-owned firms relative to domestic-owned firms; and firms in innovation-intensive industries. The effect of IPP on export product quality is statistically insignificant in certain geographic regions (i.e., central and western regions) and trade mode (i.e., processing trade). In addition, we show that the channels through which IPP takes effect on product quality include strengthened R&D input, new product development, and mitigated financial constraints.
