中文摘要：

评价改革开放34年西北五省区信息承载力的需求与供给，结果表明除陕西省外，西北五省区信息生态系统整体处于不均衡承载状态，信息压力远大于信息承载力，区域内部信息承栽力分布极不均匀，亟需发展信息治理的核心能力与应用技术，特别是信息弹性力中的社会信用体系建设与信息能力中的信息咨询与决策、信息使能技术、信息协作能力等。

英文摘要：

This article gives an empirical test on the demand and supply of the Information Carrying Capacity（ICC） in the five provinces of Northwest China, during the recent 34 years since China implemented reform and opening policy. The results indicate that Information Ecosystem of five northwestern provinces, except Shanxi Province, was not sustainable, and the distribution of regional internal ICC is uneven. As a counter measure, core competence and application technology in information governance are urgently needed, especially the social credit system construction of information bearing capacity, including information consultation and decision, information enabling technology and information cooperation ability.
