知识产权保护与企业出口技术复杂度:基于中国企业微观数据的实证分析

通过多维度固定效应模型研究中国知识产权保护对企业出口技术复杂度的影响.结果 发现,(1)整体来看,中国知识产权保护与企业出口技术复杂度之间存在显著的倒U型关系;(2)从不同所有制企业来看,相比于内资企业,外资企业中知识产权保护与企业出口技术复杂度之间倒U型关系较强;(3)从不同地区企业来看,东部地区知识产权保护与企业出口技术复杂度之间仍存在倒U型关系,中部和西部地区呈现线性促进关系.综合而言,由于中国的特殊国情和地区发展不平衡的现实背景,中国应适当地提高知识产权保护力度但又不能太过激进.

Intellectual Property Protection and Export Technology Complexity of Chinese Enterprises: An empirical analysis based on micro data of Chinese enterprises

This paper studies the influence of intellectual property protection (IIP) on the export technological complexity of enterprises through the multi-dimensional fixed effect model. The results show that :(1) on the whole,there is a significant inverted U-shaped relationship between IIP and the export technological complexity of enterprises. (2) From the perspective of enterprises of different ownership,compared with domestic enterprises, there is a strong inverted U-shaped relationship between IIP and export technological complexity of enterprises in foreign-funded enterprises. (3) From the perspective of enterprises in different regions, there is still an inverted U-shaped relationship between IIP and the export technological complexity of enterprises in eastern regions, while a linear promoting relationship exists in the central and western regions. To sum up, due to China''s special national conditions and the realistic background of unbalanced regional development, China should appropriately increase the intensity of IIP but not too radical.
