Abstract: Abstract：Using regional level panel data, this paper empirically studies the effect of basic research on technological progress. The results prove that basic research has a positive effect on technological progress on the whole, but it can’t provide sufficient bases for technology innovation and technology import to promote the technological progress. Further, with the threshold regression model we find the optimal range of the intensity of basic research investment is 0.058 to 0.084. What’s more, basic research have an reverted N-shaped relationship with technological progress by influencing technology innovation and have an U-shaped relationship with technological progress by influencing technology import. At present, the intensity of basic research investment is less than the optimal level and basic research increasing will help technology innovation and technology import to promote technological progress positively.
