摘要
本文基于不完全契约的现实背景,创新性地分析了知识产权保护对企业出口技术复杂度的作用机制。通过制造商与供应商之间的博弈均衡解,解释了在不完全契约条件下加强知识产权保护,会配置给供应商更多高技术投资收益的剩余索取权,减弱供应商被制造商"敲竹杠"的风险,激励供应商投资高技术活动,进而引致社会整体的技术水平提高。运用中国工业企业数据库与中国海关贸易数据库的匹配数据计算出企业出口技术复杂度,验证了加强知识产权保护会促进企业出口技术复杂度提升的假说。研究还发现,加强知识产权保护有利于契约密集度高的企业和非国有企业的出口技术复杂度提升,有利于缩小东部与中西部的出口技术复杂度差距。知识产权保护会激励企业的人力资本投资高技术活动,激活企业创新动力,提升企业出口技术复杂度。实证结果对于内生性、核心指标的不同测度方法、不同工具变量、不同时间区间的样本表现出稳健的特性。本文的研究结论对于如何激发企业活力和创新精神,进而实现中国经济高质量发展模式具有重要启示。
Based on the realistic background of incomplete contract, this paper innovatively analyzes the mechanism between intellectual property protection and enterprise’s export technological sophistication. On the condition of incomplete contract, this paper set a game between manufacturer and suppliers. It finds that to strengthen intellectual property protection will reallocate more residual claims of returns on high technology’s investment to suppliers, which will reduce the risk of being "ripped off" of supplier. Supplier will increase investment in high technology, which will lead to improve the technology level of whole society. Using the matching data between Chinese industrial enterprises database and Chinese customs trade database calculates export technological sophistication of enterprise. Empirical results support the hypothesis that strengthening intellectual property protection will promote export technological sophistication of enterprise. The study also found that strengthening intellectual property protection is more advantageous to increase the export technological sophistication of enterprises with the high intensity of contract, to increase the export sophistication of non-state-owned enterprises, to narrow the gap of export technological sophistication between east and mid-west. Intellectual property protection can incentive human capital investment high technical activities, activate the enterprise innovation power to improve enterprise’s export technological sophistication. The empirical results show the characteristics of the solid for endogenous, different measurement methods to core index, different instrumental voriables, different time interval of sample. This paper’s study has an important enlightenment on Chinese economy how to stimulate the enterprise’s vitality and innovation and achieve high-quality development pattern.
