Abstract:There is a complex interactive relationship between science and technology service industry and regional innovation ability.Based on an overview of Fujian's regional innovation system and science and technology service industry, the connotation of the coupling development of science and technology service industry is expounded, the evaluation model is constructed, and the coupling coordination by using the entropy weight method is empirically analyzed.The results show that the coupling level of the sample regional system continues to rise during the observation period, but the differentiation is obvious, showing a distribution pattern of "high coastal and low inland", and the coupling development needs to be promoted in depth.
