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.

摘要： 摘 要：文章运用中国地区面板数据对基础研究的技术拉动效应进行实证检验，结果表明：基础研究在整体上对技术进步存在促进作用;但未能通过技术创新和技术引进这两条途径促进技术进步。进一步的门槛检验表明我国基础研究强度最优区间为0.058-0.084，且基础研究通过技术创新促进技术进步的作用呈倒“N”型关系，通过技术引进促进技术进步的作用呈“U”型关系。目前我国基础研究强度低于最优区间，进一步提高基础研究投入有助于改善技术创新和技术引进的技术拉动效应。
