中文摘要：

本文基于2001-2015年的专利数据,通过对比中国、美国、日本和印度四国创新全球化水平,了解中国创新全球化水平,并运用分位数回归模型实证分析中国创新全球化水平的影响因素。研究结果表明：考察期内,中国、美国、日本和印度四国创新全球化水平都有所提升,特别是中国的专利技术水平增长较快;国际竞争力和技术密度会显著影响中国、美国、日本和印度四国创新全球化水平。其中,国际竞争力对创新全球化水平较低的国家影响较大,而不论国家创新全球化水平高低,技术密度对其都有影响;贸易进出口对国家创新全球化水平的影响不明确;在专利发明或者申请过程中,科技活动从业规模对中国、美国、日本和印度四国创新全球化水平也存在显著影响,并且对创新全球化水平较高的国家影响较大;在国家同时充当发明人和所有人时,技术显示比较利益对中国、美国、日本和印度四国创新全球化水平存在显著影响。

英文摘要：

This paper analyzes the globalizationlevel of China＇s innovation,through the comparison with the United States, Japan, and India based on the patent data of 2001-2015. The paper also empirically studies the determinants of China＇s innovation globalizationlevel by using quantile regression model. The results show that the globalization of innovation in the United States, Japan, China and India has improvedin the study period, and China＇s patented technology level grows rapidly; International competitiveness and technology density significantly influence the level of innovation globalization,and international competitiveness has greater influence on those countries withthe low globalization level of innovation,while technology density has great influence on all countries; the influence of global import and export trade on the globalization of innovation is not clear; in the process of patent invention or application, the scale of technology activities influences the globalization of innovation significantly, especially for the country with high globalization level of innovation; when the country is both the inventor and the applicant, revealed technological advantage has great impacts on the innovation globalization level of China, the United States, Japan and India. These findings have important implications for our country to actively participate in the global innovation chain, and to seek new impetus mechanism.
