Dataset_Intellectual Property Arms Race A Case of Inter-provincial Competition from China

Some past literature supports the insignificant relationship between intellectual property rights and productivity on the basis of global data. This result seems puzzling. This study proposes that the possible reason is the result of the inter-regional intellectual property arms race. And take the panel data of 30 provinces in China from 2000 to 2017 as an example. It is discussed by integrating research methods such as theoretical model, mechanical learning and spatial Doberman model. The final results support the initial view of this study, and the results support the existence of an inter-provincial intellectual property arms race, and continue to cause national-level intellectual property rights to have an insignificant impact on the overall national productivity.

既往已有文献基于全球层面数据，证实知识产权(Intellectual Property Rights, IPR)与生产率之间不存在显著关联。这一结论看似令人费解。本研究提出，其潜在成因源于区域间的知识产权军备竞赛。本研究以中国2000年至2017年30个省份的面板数据(panel data)为研究样本，整合理论模型、机器学习(Machine Learning)与空间杜宾模型(Spatial Durbin Model)等研究方法展开探讨。最终研究结果验证了本研究的初始观点：我国省际间确实存在知识产权军备竞赛，该竞赛最终使得国家级层面的知识产权对全国整体生产率未产生显著影响。
