摘要

我们研究了日本人对能源和环境问题兴趣的长期变化与主要由新闻媒体发布的信息的相关性。通过对全球变暖、节能和自然三件事的公众利益程度的调查,我们提出了一个模型,将公众利益与获得的公众知识作为公众对主要由新闻媒体提供的信息的记忆函数。在这里,社会被假设沉浸在一个虚拟的信息环境场域中,这激发了公众的集体兴趣,并与公众记忆与遗忘的程度成正比。通过引入两种类型的遗忘函数,我们发现该模型可以很好地再现日本人兴趣的实时变化,除了自然的情况,几乎与函数的形式无关。一些人评论说,当这个领域被削弱时,公众利益的衰减就会发生。

Public Interest Immersed in the Field of Information Environment: How has Japanese Interest in Energy and Environmental Problems Varied?
We studied the relevance of the secular variation of Japanese interest in energy and environmental problems to the information primarily released by the news media. From the investigation of the extent of public interest in three matters, the global warming, the energy saving and nature, all indicated by opinion surveys, the number of newspaper articles and the frequency of Internet retrieval search, we proposed a model such that the public interest along with the acquired public knowledge were given as a function of public memory of the information primarily provided by the news media. The society was assumed here to be immersed in a virtual field of information environment, which induced the collective interest of the public and was proportional in strength to the extent of the public memory with oblivion. Introducing two types of oblivion function, we found the model to well reproduce the real time-variation of the Japanese interest, except for the case of nature, almost irrespective to the form of the function. Some comments were made on the attenuation of the public interest that occurred when the field became weakened.
