【摘要】 政府信息共享是电子政务建设的重要内容之一,政府组织间的信任则可以降低政府组织在信息共享与合作中的成本,提高其工作效率,从而更好地为社会公众服务。政府组织间相互的不信任是导致组织间信息共享失败的重要原因,而利益冲突则是导致组织间不信任的重要原因,政府组织间信任缺失影响了政府部门及时有效地利用信息资源进行决策,影响了电子政务公共服务水平。目前政府组织间的信息共享有直接信任模型和第三方信任模型,其中第三方信任模型没有解决政府组织间信息共享中的风险和利益冲突问题,且当共享方的数量大量增加时,政府组织间信息共享中的风险和利益冲突管理变得异常复杂,另外这种模型构建可信任的第三方和失效问题也是一个缺陷；而直接信任模型在实际的应用中却有很好的效果,但信任关系的度量是一个难题。论文提出了政府组织间信息共享的直接信任和推荐信任模型,为政府组织间信息共享提供决策支持,并给出了政府组织间信息共享能力的测度方法。首先,提出了政府组织间信息共享的直接信任评估模型,对一次共享交互的满意度即信任度进行评价,进而提出松散型政府组织间的直接信任及更新模型,解决了政府组织间信息直接共享的决策问题。其次,提出了政府组织间信息共享的信任传递模型,构建了推荐信任的传递路径并给出了推荐信任的计算模型,解决了松散政府组织间信息共享的决策问题。最后,提出了基于灰色模糊理论的政府组织间信息共享能力测度方法,构建了一个完整的政府部门间的信息共享能力测度的指标体系和测度模型,解决了政府组织间信息共享的能力测度问题。论文首次将信任的度量方法引入到政府组织间信息共享问题的研究,并针对政府组织间信息共享的影响因素和政府信息的特点,提出了政府组织间信息共享的信任模型,并通过实例和仿真实验验证了其有效性,该模型可为政府组织间信息共享提供决策依据,政府组织间信息共享能力测度方法对于评估和提高政府组织间信息共享的程度和水平,具有重要的参考价值和意义。更多还原

【Abstract】 Government information sharing is one of the important parts in building e-government. The trust among government organizations is able to reduce the cost when they share information and cooperate as well as improve efficiency, and then government can bring us better service. Government organizations’distrust is an important factor which causes the failure of inter-organizational information sharing, moreover, the conflict of interest is also an important reason for organizations distrust. The lack of trust among government organizations the effective and timely use of information resources to make decision, and influences the standard of e-government public service. Today, the model of the information sharing among government organizations can be divided into the direct trust model and the third-party trust model. However the third-party trust model doesn’t solve the problem of risk and conflict of interest during information sharing, and when the number of the sharing parties increases sharply, this kind of risk and conflict’s management becomes extremely complex. In addition, it is also a defect of this model when building a trusted third-party. Direct trust model has good effect in practical applications, but the measure of the trust relationship is a problem.In this essay, it advances a direct trust model and a recommendation trust model for information sharing among government organizations in order to provide decision support for information sharing, it also give a measurement method to measure the ability. First, it proposed two models, the direct trust evaluation model to evaluate the satisfaction and trust degree during one sharing interaction, the direct trust and update model among loose-government organizations to solve the decision-making problems during the direct information sharing. Secondly, it puts forward a trust transfer model, in which the recommended trust transfer path and calculation model of recommendation trust are given to solve the decision-making problems for information sharing among loose-government organizations. Finally, it advances a information sharing ability measurement method which bases on the gray fuzzy theory, and then constructs a complete index system and measurement model that are used in the information sharing ability measurement among government departments, this model solves the problem of measuring ability of the information sharing among government organizations.In this essay, the method to measure trust is first used in the research on information sharing among government organizations. It proposes a trust model which is used in the government organizations. The model’s setting is according to the information sharing influence factors and the feature of the government information. The effectiveness of this model has been verified by examples and simulation experiments. The model can provide decision-making basis for information sharing among government organizations. The measurement method to measure the ability of information sharing among government organizations has important reference value and significance to evaluate and improve the level of information sharing among government organizations.更多还原
