知识产权保护与产业技术进步——基于中国工业面板数据的经验研究

Intellectual Property Protection and Industrial Technological Progress——Empirical Study Based on China Industrial Panel Data

基于2001—2015年工业行业数据,实证研究了知识产权保护对产业技术进步差异的影响机制。研究发现,知识产权保护强度促进了产业技术进步,更为重要的是上述两者之间存在显著的倒“U”型关系,但是上述相关性受到融资成本、资产规模、技术敏感度和宏观经济环境冲击等因素影响。具体来说,在知识产权保护强度既定的条件下,与大企业相比,中小企业更有激励进行研发投入;同时,知识产权保护强度的积极影响在产业技术敏感度相对较高的行业更大;2008年金融危机后的经济扩张政策降低了知识产权保护的正面影响。

Based on the industrial industry data from 2001 to 2015,this paper empirically studies the influence mechanism of intellectual property protection on the difference of industrial technological progress.According to the research,the intensity of intellectual property protection has promoted the technological progress of industry,and more importantly,there is a significant inverted“U”relationship between the two,but the above correlation is affected by the factors such as financing cost,asset size,technology sensitivity and macroeconomic environmental impact.Specifically,under the conditions of established intellectual property protection intensity,small and medium-sized enterprises have more incentive to invest in R&D than large enterprises;at the same time,the positive impact of intellectual property protection intensity is greater in industries with relatively high industrial technology sensitivity;and the economic expansion policy after the 2008 financial crisis has reduced the positive impact of intellectual property protection.
