Analysis on Knowledge Innovation Efficiency of Agricultural Sci-tech Journal Community: Perspective of Knowledge Communication

摘要

As a key content of the development of agricultural science and technology disciplines, the construction of the journal community has a strong practical significance in carrying out research on its knowledge innovation effectiveness. The effectiveness of knowledge innovation in the community of agricultural sci-tech journals was evaluated by using the non-parametric DEA-Tobit two-step model combined with the Citation Report of Chinese Sci-tech Journals (Expanded Edition), and the factors that affect the efficiency of the knowledge innovation in the journal community were argued. The conclusions are as follows: (1) Overall, the achievement of knowledge innovation in the community of agricultural sci-tech journals still has 34.4% of optimization space. The low efficiency of pure technology has a big impact. (2) There are large differences in the journal community, among which Beijing Agriculture, Higher Agricultural Education, such as Quality and Safety of Agro-Products, Journal of Agricultural Sciences, China Agricultural Technology Extension, Chinese Journal of Agrometeorology, and other 12 journals have relatively stable knowledge innovation efficiency. In addition, the technical efficiency, pure technical efficiency, and scale efficiency value are all 1. (3) The academic quality of journal papers is an important factor in the efficiency of journal community knowledge innovation. The duration of the publication and The economic status of the region where the journal is located are also positive factors affecting the efficiency of knowledge innovation in journals of agricultural science and technology. The variables such as The degree of cooperation in journals. The degree of journal globalization and The distribution of journal dissertation institutions have limited impact on the efficiency of the journal community's knowledge innovation. In addition, due to the weak timeliness of agricultural science and technology literature, the author's utilization of Citation half-life as a measure of the degree of novelty of the use of the literature as a whole affects the performance and expectations of knowledge exchange.
