International Capital Flows, Export Technology Complexity And Total Factor Productivit

To achieve high-quality and sustainable development of China’s economy,it is necessary to continuously improve China’s Total Factor Productivity(TFP).Therefore,how to improve China’s total factor productivity is an urgent problem for China to transform its economic development mode.There are two ways to improve a country’s total factor productivity(TFP): one is through independent innovation by increasing domestic R&D capital investment,the other is through the introduction of foreign advanced technology and management methods and other technology diffusion channels.With the improvement of China’s technology and the change of export structure,the effects of FDI and import and export affecting total factor productivity(TFP)have changed,and the technological progress brought by technology diffusion channels is no longer significant.Previous scholars mostly analyzed the impact of foreign direct investment(FDI),import and export on China’s total factor productivity(TFP)from the perspective of technology spillover.When technology reaches a certain level,will foreign direct investment,import and export improve China’s total factor productivity by promoting China’s independent innovation? Is the promotion effect strengthened or weakened? Therefore,this paper introduces the index of export technology complexity as a threshold variable to study whether there is a threshold value for the impact of international capital flows(FDI,international trade)on China’s total factor productivity with the change of export technology complexity.This paper calculates the total factor productivity and export technology complexity of 30 provinces and cities(except Tibet)from 2010 to 2020.Through establishing a dynamic panel threshold model,the following conclusions are drawn:(1)The export technology complexity will affect the effect of FDI on total factor productivity;In addition,when the level of export technology complexity is low,FDI has less effect on promoting the improvement of total factor productivity.When the level of export technology complexity is high,FDI has greater effect on promoting the improvement of total factor productivity.(2)The complexity of export technology will affect the effect of international trade on total factor productivity;In addition,when the level of export technology complexity is low,the promotion effect of international trade on total factor productivity is small.When the level of export technology complexity is high,the promotion effect of international trade on total factor productivity is large.Then this paper puts forward relevant policy recommendations: provinces and cities should adjust the export structure and increase the complexity of export technology;We will strengthen the introduction of foreign capital,expand international trade,and serve domestic innovation.
