近年来，我国致力于数字政府的建设与发展，数字化进程取得了显著的成效，与此同时，各地移动政务平台被陆续推出，移动端政务管理也已全面进入3.0时代。然而，并非所有公民都能很好的利用政府所提供的便捷服务，其中老年群体的使用困境尤为突出。基于以上背景，本文以吉林省移动政务微信小程序平台“吉事办”作为研究对象，以该省60岁及以上老年人作为研究样本，采用结构方程模型的分析方法，分析影响老年人使用意愿的影响因素，以期为移动政务的发展提供参考依据。
首先，为了深入分析影响老年群体移动政务使用意愿影响因素，本文将技术接受模型(TAM)、计划行为理论(TPB)和信任理论(TT)进行了整合，同时结合老年群体的特殊属性构建了老年人移动政务平台使用意愿影响因素模型，并提出了8项研究假设，分别是：感知信任、感知行为控制、主观规范、使用态度正向影响老年人使用意愿；政府信任和网络环境信任正向影响感知信任；感知易用性和感知有用性正向影响使用态度。而后为了检验理论假设及相关模型是否成立，通过问卷调查法对吉林省60岁及以上老年群体（n=248）进行抽样调查，并利用结构方程模型对测量模型的信效度、路径关系以及模型适配度方面进行了实证分析。
经过探索性因子分析和验证性因子分析结果显示：模型整体拟合度较好，信效度均符合相关标准，并且其中七项研究假设成立，具体包括：感知信任、感知行为控制、主观规范和使用态度对使用意愿有显著正向影响；网络环境信任对感知信任有显著正向影响；感知易用性和感知有用性对使用态度有显著正向影响。一项研究假设不成立，即政府信任对感知信任无显著影响。
最终基于以上研究分析结果，结合我国数字治理现状及移动政务发展情况，在感知信任、感知行为控制、主观规范和使用态度四个方面提出优化吉林省移动政务微信小程序平台“吉事办”的对策建议。

In recent years, China is exerting its efforts to construct and develop a digital government, which has achieved remarkable results up to now. At the same time, with more and more mobile government platform being launched successively, the mobile government management has entered the 3.0 era. However, not all citizens can make good use of the convenient services provided by the government, among which the plight of the elderly is particularly prominent. Under such background, by adopting the analysis method of structural equation model, this paper takes the "Jishiban" WeChat mini program of Jilin province mobile government platform as the research object, the elderly aged 60 and above in the province as the research sample, to analyze the factors that affect the willingness of the elderly to use this platform, in order to provide references for the development of mobile government.
First of all, in order to make an in-depth analysis, this paper integrates the technology acceptance model (TAM), planned behavior theory (TPB) and trust theory (TT). At the same time, it constructs a model of the influencing factors of the elderly's willingness to use the mobile government platform, combining with the special attributes of the elderly group. Eight research hypotheses are put forward, which are perceived trust, perceived behavior control, subjective norms, use attitude positively affecting the elderly’s willingness to use; government trust and network environment trust positively affecting perceived trust; perceived ease of use and perceived usefulness positively affecting use attitude. Then, in order to test the theoretical hypothesis and related models, a sample survey is conducted among the elderly aged 60 and above in Jilin Province (n= 248) by questionnaire. In addition, the structural equation model is used to analyze the reliability and validity, path relationship and model fitness of the measurement model.
The results of exploratory factor analysis and confirmatory factor analysis show that the overall fit of the model is good, the reliability and validity of the model are in line with the relevant standards. And seven of the eight research hypotheses are tenable, including: perceived trust, perceived behavior control, subjective norms and use attitude have a significant positive impact on use intention; network environment trust has a significant positive impact on perceived trust; perceived ease of use and perceived usefulness have a significant positive impact on the attitude towards using. One study assumes that government trust has no significant effect on perceived trust.
Finally, based on the above research results, considering the current situation of digital governance and the development of mobile government in China, this paper puts forward some countermeasures and suggestions to optimize the "Jishiban" WeChat mini program platform of Jilin mobile government in the four aspects of perceived trust, perceived behavior control, subjective norms and attitude towards using.
