Using entropy method and coupling coordination model ,the coupling coordination relationship between rural high-quality development and the promotion of sci-tech experts system in Fujian Province from 2016 to 2020 is studied . The results show that the comprehensive development level, coupling degree and coordinated development degree all present an increasing trend, the spatial pattern of coastal area is larger than that of mountainous area from the regional perspective, and the coupling coordination type is still in the running-in phase. Therefore, it is suggested that Fujian Province should perfect the top-level design, deepen the system innovation, cultivate and strengthen the regional characteristic rural industry, and reconstruct the rural science and technology service mode.
