1932年5月5日中日签订《淞沪停战协定》,在上海及其周边地区划定所谓“停战区”,对中国主权造成极大损害。值得注意的是,“停战区”范围除协定规定者外,事实上还包括苏州河以南与浦东地区,极大限制了中国军队的驻扎与调动。在“停战区”问题上,中方长期忍气吞声,受日方压迫,进而书面承诺,致使“停战区”机制完全确立。列强则纵容日方扩张在沪军事利益,进行偏向性的“国际协调”。然而,受局部抗战走向的影响,停战协定效力的限度愈发凸显,国民政府期待废约,日方的侵略野心则导致它必然要打破“停战区”的限定。因此,日本威慑下的“停战区”机制最终导致上海再次发生大规模战争,“八一三”战事成为“停战区”的破局点。“停战区”机制是推动局部抗战走向全面抗战的重要因素。

问责是约束权力、推动全面从严治党的重要治理工具,而问责泛化与简单化却损害了问责的严肃性和权威性。结合2016—2021年间19个公职人员问责泛化案例,运用内容分析法的研究策略,在系统梳理和分析问责泛化类型及其表现的基础上深入挖掘问责泛化现象背后的生成逻辑,可以发现:无论在常规治理情境下,还是在非常规治理情境下,问责泛化现象的生成均源自问责扮演了一种“被异化的工具”的角色,这种工具异化现象由问责启动条件、问责制度本身、问责运行环境和相关治理主体等方面的现实条件导致。未来需要在明确问责启动条件、完善问责的外部监督机制、理顺党政治理的权责关系和提升党政治理主体的治理能力四个方面深入探索,切实实现问责的精准、有效。
