With the all-round promotion of the "Belt and Road Initiative," China's investment in the countries along the line has gradually expanded, but its investment efficiency has been relatively low. Based on this, taking the panel data of 46 countries directly under the "Belt and Road" from 2006 to 2015 in China as an example, the paper uses a stochastic frontier model to evaluate the investment efficiency and its changes comprehensively. The research shows that the overall efficiency of China's investment in the countries along the line is not high, and In the meantime, the investment efficiency of our country along the line shows a slight downward trend during the period of investigation, and the rate of technological progress is the main factor restricting the investment efficiency. To this end, we should optimize investment structure and location selection, and strengthen the investment skills. Innovate in technology, construct a transnational knowledge network system, deepen capacity cooperation between the two sides and enhance the agglomeration of investment industries.
