低碳知识的时空扩散与演变特征研究

基于维普中文科技期刊全文数据库中相关文献的时空分布变化，考量我国低碳知识经济扩散的形式、特征规律。结果发现：低碳知识在我国的时间扩散经历了接收、启动、加速、回落四个时期；低碳知识扩散中，政府是主导者，学者是领先者，企业是跟进者、居民是接受者；北京是我国低碳知识的扩散源，城市地位和文化科研实力是重要保障；低碳知识在我国的空间扩散既符合整体规律又表现出差异化。

Study on Time-Space Diffusion and Evolution Characteristics of Low Corbon Knowledge

This paper explores the diffusion patterns and characteristics of Chinese Low car-bon knowledge economy based on spatial and temporal changes of published articles.The re-search was based on bibliometric approach of collecting,organizing and analyzing articles related to Low carbon knowledge and published in journals retrieved by China Science and Technology Journal Database of VIP.This is intended to capture properties of temporal and spatial diffusion patterns.And the characteristics of diffusion sources,diffusion time and provincial diffusion were examined as well.In conclusion,the Low carbon knowledge diffusion process had undergone four steps,adoption,activation,acceleration and decline.During the process of Low carbon diffu-sion,where government plays the leading role, scholars act as the pioneers following by enterprises,and residents are the recipients.On account of the city statue and cultural and scien-tific strength,it is identified Beijing is the diffusion source of Chinese Low carbon knowledge.It is also verified that the performance of Low carbon knowledge diffusion consolidates integrated characteristics and exhibits its differentiation as well.Furthermore,the policy recommendations are proposed accordingly.
