论税务约谈机制的制度缺失及完善建议

税务研究 2024年第1期 76-82页

作者：廖仕梅北京理工大学法学院

税务约谈属于争议预防机制、非强制性行政行为,不是纠纷解决机制,不同于和解及调解机制,也不同于询问。税务约谈在创建公平对话平台、对纳税人违法预警、有效防范税务执法风险等方面能发挥积极作用。目前税务约谈机制存在的缺陷主要表... 详细信息

税务约谈属于争议预防机制、非强制性行政行为,不是纠纷解决机制,不同于和解及调解机制,也不同于询问。税务约谈在创建公平对话平台、对纳税人违法预警、有效防范税务执法风险等方面能发挥积极作用。目前税务约谈机制存在的缺陷主要表现为法律依据不足、适用范围过窄、对有欺诈行为的纳税人缺乏惩戒措施、对纳税人的权益保护不够。借鉴美国、澳大利亚等国的相关立法并结合我国实际情况,建议通过以法律形式规范税务约谈机制、扩大税务约谈的适用范围、鼓励纳税人配合税务约谈、注重对纳税人权益的保护等措施,不断完善我国的税务约谈机制。

为预防地铁站火灾事故,深入了解地铁站火灾人员疏散影响因素间的内在联系与层次结构,基于第6版“2-4”模型(24Model)分析63起地铁站火灾疏散事故,充分考虑各个因素之间的交互作用,提取19个影响地铁站人员疏散的关键因素,建立地铁站火灾人员疏散影响因素指标体系;采用算子客观赋权法(C-OWA)改进决策试验与评价实验法(DEMATEL),确定地铁站火灾人员疏散的重要影响因素;在此基础上,采用解释结构模型(ISM)分析各个因素间的层次结构及相互作用路径,构建地铁站火灾人员疏散影响因素的多级递阶结构模型。研究结果表明:疏散引导、恐慌从众行为、人员拥挤为地铁站火灾人员疏散的关键影响因素;地铁站火灾人员疏散受表层因素、中间层因素、深层因素共同作用的影响,其中,疏散教育与培训、设施维护与检查、疏散预案等因素是根源影响因素,重视根源影响因素的改善有利于从本质上预防和控制事故的发生。
