摘 要:电信流是一种存在于空间反映人类的通信活动,电信流的大小是反映一个国家经济发展水平与利用ICTs技术的主要依据。本文在回顾自1970年以来国家间电信流研究的成果和发展过程的基础上,从模型进程中透视了电信流影响因子指标体系的变化,提出影响国家间电信流的八类因子:电信设备、经济发展、国际贸易、国际旅游、国家联系、政府促进、文化联系、空间结构。本文以西太平洋地区为例,运用数学方法对各类影响因子进行分析、排序, 并创新性地从分析结果中将各种物质流对电信流的作用归结为4种形式:增强、替代、协同和衍生作用。Country is a basic unit in international scale and the relations among countries need the support of telecommunication flows.Telecommunication flows constitute a space which reflects human communication activity while the size of telecommunications flows is the main basis reflecting a national economic development level and utilization of ICTs technology. This paper reviewed the investigation result and development process of country-to-country telecommunication flows since 1970, and eight kinds of explanatory variables (telecommunication equipment, economic development, international trade, international travel, country relationships, government advance, cultural relationships, and spatial structure) which affected telecommunication flows are identified. We can see the change of the factor index system affected by the telecommunication flows in the process of modelling. This article uses the mathematics method to analyse the factor index and arrange them in order by to telecommunication flo taking Western Pacific as an example. The functions of various kinds of material flows ws can be categorized into four, namely, the function, coordinating function and deriving function.
