中文摘要：

在电子政务项目建设过程中,需方通常会参与供方主导的开发活动,并由此对项目绩效产生重要影响.然而在制定需方参与活动方案时,依赖主观直觉和经验的做法一方面对制定者提出了很高要求,另一方面容易产生争议.为此,提出通过对客观存在的历史数据进行定量分析,建立需方各参与活动对于项目绩效的影响关系,进而为需方参与活动提供建议指导.使用定量方法收集25个中国电子政务项目的数据,提出一种基于变量选择的回归分析方法,建立需方参与活动与项目绩效之间关系的量化模型,并对模型的有效性进行了计量分析.分析结果显示,该模型具有良好的数学性质.进一步地,对相关软件企业进行了回访,结合模型结论对反馈结果进行综合分析,为中国电子政务项目中的需方参与活动给出若干具体建议.

英文摘要：

During the construction process of an e-government project,the acquirer commonly participates in a series of development activities handled by suppliers.These participation activities have a significant influence on the project performance.However,when planning for participation activities that rely on subjective intuition this raises a tense claim on policymakers’ capacity,and can arouse controversy.To this end,the study proposes an alternative approach,which relies on objective knowledge from historical data.The study collects 25 completed Chinese e-government projects,leverages on a variable-selection-based regression analysis,and establishes a model of quantitative relationship between the acquirer’s participation and project performance.The model has good mathematical properties.The study further examines the model’s degree of conformity to common experiences of project managers.Taking all the comparison and analysis in consideration,the study proposes several suggestions for acquirers in Chinese e-government projects.
