Abstract Collaborative innovation requires breaking through barriers between innovation subjects and objects, and promoting the flow of science and technology to release the vitality of innovation elements. This paper constructs a gravity model of the potential of inter-regional science and technology flow, calculates the technology absorption level of different degrees formed by the geographical, economic and technological differences between regions through the different matrix of geographical distance, economic distance and technological distance. Then, the geographical barriers, economic barriers and technological barriers of science and technology flow were calculated by the improved Romer model. The results are obtained as follows: As far as the whole country is concerned, geographical barriers have the strongest binding effect, but weakened after 2009; technological barriers have the least restrictive effect, but there was a growing trend after 2014; the trend of economic gap barriers is the same as the total barriers, which is the most important factor affecting the effective circulation of science and technology in the later period; the total barriers to the flow of science and technology in China show a trend of decreasing in fluctuation, and have been dominated by geographical barriers, economic barriers and technical barriers one after another. From a spatial perspective, non-administrative barriers hindering the flow of science and technology have obvious spatial distribution differences. Geographical barriers are more prominent in northeast and western border areas, and economic barriers are more obvious in northeast, northwest and central areas, while technical barriers are mainly concentrated in north and southwest areas. Finally, according to the conclusions of the study, relevant policy recommendations are put forward to promote the flow of science and technology among regions.
