Impact of Intellectual Property Protection Level of Countries Along the Belt and Road Initiative on China's Digital Product Export Efficiency
Taking 45 countries along the Belt and Road initiative as examples,based on the panel data of China's digital product exports from 2006 to 2018,the stochastic frontier gravity model proposed by Miyusen(1977)and Schmidt(1977).Empirical analysis of the impact of intellectual property protection level of countries along the Belt and Road initiative on China's export efficiency of digital products,and measurement of China's export efficiency to countries along the Belt and Road initiative.The results show that the improvement of intellectual property protection levels in countries along the Belt and Road initiative significantly promotes the efficiency of China's digital product exports to these countries;the average trade efficiency of China's exports to various countries is at a moderate level,and there is great room for improvement.
