### The Interaction of Science-Technology  
Science is the theoretical basis for technological development, and technology, in turn, promotes the in-depth development of science [5]. As early as the 1860s, researchers discovered that with the shortening of innovation cycles, the connection between technology and science was becoming increasingly closer. [PERSON] et al. [6] pointed out that the generation of technological knowledge stems from the development of scientific knowledge and its migration to the technical field. The correlation between the two is reflected in the dependence of technological activities on science. [PERSON] et al. [7] compared technology and science to a pair of dancers, believing that they are closely related. In 1997, [PERSON] [8] proposed [PERSON]'s Quadrant innovation theory based on organizing science and technology as well as basic research and applied research. This innovation theory more accurately reflects the actual situation of scientific research and holds that there is a dynamic association and interweaving between basic research and applied research [9]. On the one hand, the change in scientific knowledge or scientific paradigms can play a significant role in guiding technological innovation and breaking through technological bottlenecks [10]. On the other hand, technology is also the main means with which to verify whether scientific theories are correct, which provides better conditions and more comprehensive perspectives for scientific research [11; 12]. [PERSON] et al. [13], through empirical research, found that patents citing published materials would gain more citation influence. Meanwhile, they believed that basic science has important value in stimulating technological innovation. [PERSON] et al. [14] elaborated on the correlation between science and technology through system theory. They found that the two can restrict and link with each other, and then form a new overall collaborative effect. In addition, scholars have also found that there are diverse interaction modes between science and technology. [PERSON] [15] deeply analyzed the correlation relationship between science and technology with the help of the multidimensional analysis method. It was found that there is a nonlinear and non-univocal interaction between the two. [PERSON] [16] classified the interaction between science and technology into four types according to the direction of their effects. They are that science precedes technology, science and technology are relatively independent, technology precedes science, and there is a two-way interaction between science and technology. [PERSON] et al. [12] summarized four interaction modes between science and technology according to the intensity of their effects. They are the integration between science and technology, the interactive collaboration between science and technology, the knowledge transfer between science and technology, and the dependence of technology on science. In summary, the relationship between science and technology is not a simple one-way derivation, but a complex and dynamic interactive process. Identifying and understanding the correlation relationship between science and technology is of great significance for promoting scientific and technological innovation in relevant fields.
