Abstract: Due to the technology gap between developed countries and developing countries,the advanced technology will spread from developed countries to developing countries through various channels during economic exchanges.Based on the collection of provincial panel data from 2007 to 2017,this paper establishes a recursive model and a non-recursive model,and uses Partial Least Squares(PLS)method to measure the effect of technology diffusion from the United States to China.The results show that the indicator for technology gap between China and America doesnt promote technological progress,while the international trade,FDI between China and the United States promote Chinas technological progress.In addition,Chinese government policy,economic environment,infrastructure,and so on,affect the technology diffusion between China and the US,and are positively correlated with Chinas technological progress.By the comparative analysis of the empirical results of the recursive model and the non-recursive model,it shows that whether the model considers the mutual influence between independent variables has a certain influence on the empirical results of the model,but the degree of influence is not too much.

Key words: the effect of technology diffusion, structural equation model, path analysis
