摘要
随着全球化的深入发展,各国之间交往日趋频繁,竞争也愈发激烈,同时中国经济发展进入新常态,中国迫切需要通过加大自主创新、调整产业结构、转变发展方式来提高国际竞争力。出口技术复杂度反映了产品的技术实力和生产效率,提高出口技术复杂度对于优化产品结构、促进产业转型升级具有重要作用。知识产权制度能够激励技术进步,并为提高出口技术复杂度提供较为优越的环境。利用28个制造业行业2001—2011年的数据,实证分析知识产权保护对中国出口技术复杂度的影响,结果表明,加强知识产权保护能够显著促进中国出口技术复杂度的提升。异质性检验发现,从要素投入密集度看,知识产权保护对技术密集型行业的积极影响最大,对资本密集型行业的积极影响次之,对劳动密集型行业有负向影响;从工业产值规模看,知识产权保护对高工业产值行业和低工业产值行业均有显著的积极影响,并且对前者的影响更大。影响机制检验表明,知识产权保护还通过自主创新、对外直接投资、进口贸易间接影响出口技术复杂度,自主创新是促进中国出口技术复杂度提升最重要、最有效的渠道。
Export technical complexity reflects the technical strength and production efficiency of products and it plays an important role in optimizing product structure and promoting industrial transformation and upgrading. Intellectual property system can stimulate technological progress and provide a better environment for improving the technological complexity of export products.Based on the data of 28 manufacturing industries from 2001 to 2011,the paper empirically analyzes the impact of intellectual property protection on China’s export technological complexity.The results show that strengthening intellectual property protection can significantly promote China’s export technological complexity. Heterogeneity test found that from the perspective of factor input intensity, intellectual property protection has the greatest positive impact on technology-intensive industries,followed by capital-intensive industries and negative impact on labor-intensive industries. Judging from the scale of industrial output value,intellectual property protection has a significant positive impact on both high-industrial output value industries and low-industrial output value industries,and the impact on the former is greater. The test of impact mechanism shows that intellectual property protection also indirectly affects export technological complexity through independent innovation, foreign direct investment and import trade.Independent innovation is the most important and effective channel to promote China’s export technological complexity.
