Abstract: The “Belt and Road” initiative provides an opportunity for China to transfer technology to emerging market countries along the belt and route. Based on the fundamental idea of policy evaluation, a difference in difference model is adopted in this paper and 56 emerging market countries along the “Belt and Road” and 89 non-“Belt and Road” emerging market countries are selected as research samples, and the research takes the “Belt and Road” initiative as a quasi-natural experiment to empirically examine the policy effect of the “Belt and Road” initiative on China's technology transfer to emerging market countries along the belt and route through counter-factual inference. The study finds that as China's strategic macro-public policy, the “Belt and Road” initiative has played a positive role in promoting technology transfer from China to emerging market countries along the belt and route, and it provides support for elements such as environment, technology, and taxation through the policy tools under the subsystem of policy and their cross-combination. At the same time, the conclusions of this paper provide micro-level support for the deep implementation of the “Belt and Road” initiative and technology transfer form China to emerging market countries along the belt and route.
