基于元胞自动机的创新扩散模型综述

元胞自动机（CA）是一种微观仿真模型，通过在微观层面上模拟个体行为和属性，自底向上地构建模型．更符合创新采纳的真实过程．是研究创新扩散的一种重要方法，CA模型应用于创新扩散已有十多年的时间．但至今仍然缺乏一个统一的研究体系．尚未见有相关的总结性文章发表。本文对这些模型进行综述性研究．旨在找出其中的内在联系．给出一个该领域的研究分析框架。首先从介绍CA入手，用一个具体的扩散模型说明了CA各要素的定义；接下来借鉴Mahaian对数学模型的分类方法将CA模型分为基本模型和扩展模型，并分别对这两类模型进行综述性研究；最后对当前研究的优势和不足分别进行了讨论。

A Review of Innovation Diffusion Models Based on Cellular Automata

Cellular Automata models are simulations of global consequences,based on local interactions between individual members of a population,which are actually the process of making an adoption decision and widely used in the area of (innovation) diffusion.Though the Cellular Automata models have been used to research innovation diffusion for more than 10 years,there still wasn't a paper that gives out a research framework of this area.The purpose of this paper is presenting a general underlying structure of Cellular Automata models of innovation diffusion by reviewing the models appeared in the past 10 years.Firstly,we introduced the Cellular Automata and presented a general model structure.To be followed,we reviewed the basic models and set up the structure framework of modeling innovation diffusion with Cellular Automata.(Finally,) we discussed the advantage and disadvantage of current researches.
