进入新世纪以来，社区服务在中国城市经济社会发展中的地位和作用与日俱增。党的十六大明确提出“发展社区服务，方便群众生活”。信息化作为提供和改善社区服务的手段，广泛应用于城市社区中，社区信息化成为城市信息化建设的重要组成部分。本文以城市社区作为研究对象，比较分析了当前国内典型城市：北京、上海、杭州和广州的社区信息化建设模式特点和建设中存在的问题。从社区服务供给的角度，分析了实践问题产生的原因，主要表现为政府主体提供公共服务的低效率、商业主体提供便民服务的无动力和居民自治主体提供公益服务的无秩序。在需求导向整合供给思路下，提出改善社区服务信息化建设需要建立多元化的社区信息化建设与运营模式、增强各类社区服务渠道的信息服务能力、提高公民的信息素质、强化建设的过程管理，从而形成“政府引导、部门协调、管理规范、社会参与、市场运作”的良性运行机制。

As the twenty-first century opens, the community service plays increasingly a substaintial role in social and economic development. Since the words “Developing community service, to facilitate the life of public” firstly proposed clearly in the political report of the 16th conference of Communist Party of China，the informationization is applied to the urban community widely as the means of improving the community service. And the community informationization has been one of important parts of urban informationization.This thesis focuses on urban community informationization, comparing the characteristics and analyzing the problems of the community informationization construction mode in the typical city of China, such as Beijing, Shanghai, Hangzhou and Guangzhou. From the perspective of the community service supplies, the factors leading to the present problems are pointed out mainly as the poor efficiency of the public service from the government, the lack of motive force of the business service from the enterprise and the lack of order of the self-governance service from the self-governance organization. According to the theory of demand orienting supply, the suggestions of improving the community service informationization are discussed as setting up diversified mode of information construction and operation, strengthening the information service’s ability of all kinds of community service channels, improving the citizen's information quality and strengthening the full-process management of the construction, in order to establish the positive operation mechanism of community service informationization which is” government guidance, department coordination, standardized management, community involvement and market operation”.
