In the wave of digitalization driven by rapid advancements in information technology, the digital transformation of governance methods has become a leading trend in government reform. Constructing a transparent, open government, illuminated by sunlight, is an important approach to achieving digital transformation and reshaping the relationship between government and citizens. This paper starts with the era's backdrop of digital government construction and, based on Chinese Social Survey, systematically discusses the systemic impact of government information disclosure on citizen opinion expression. The research finds that government transparency significantly enhances the activeness of citizen opinion expression, and this effect varies with the degree of digital transformation at the local level. Analysis of the mediating effects reveals that government responsiveness and societal fairness perceptions are crucial mechanisms explaining the relationship between the two. This study enriches the process perspective of the "government-citizen" relationship to a certain extent. Constructing a people-centered, open government will likely become a future trend in digital transformation.

在信息技术更新迭代的数字化浪潮中,实现治理方式的数字化转型成为政府改革的前沿趋势。建设阳光、透明、开放的政府,是实现数字化转型、重塑政府和公民关系的重要方式。本文从数字政府建设的时代背景出发,基于中国社会状况综合调查数据,系统讨论政府信息公开之于公民意见表达的系统性影响。研究发现政府信息公开显著提升了公民意见表达的活跃性,这种影响效应会因地方数字化转型程度而产生差异。通过中介效应分析发现,政府回应力和社会公平感构成了解释两者间关系的重要机制。本研究在一定程度上丰富了 “政府 公民”关系的过程视角,建设以人民为中心的开放型政府,将会成为未来数字化转型的可能趋势。
