本文基于对北京和上海两地48名家政女工的深度访谈,分析了户籍制度和市场双重影响下家政女工的“边界协商”,即在结构限制下形成的“生产-再生产”安排。本文认为,城乡二元结构和市场是以家庭为中介来影响家政女工个体的“生产-再生产”安排。城乡二元结构对女工家庭不同程度的影响形成了不同程度的、以家庭为单位的“生产与再生产拆分”情况;而市场对女工家庭不同程度的影响,则形成了不同程度的“家庭再生产商品化”情况。在不同“生产与再生产拆分”程度和不同“家庭再生产商品化”程度的交织中,家政女工形成了四种类型的“生产-再生产”形态,分别为“生产从属于再生产”“生产中心、再生产剥离”、“生产与再生产轮换”和“再生产从属于生产”。

前面几位老师提出了很多很重要的问题,我将从方法论的角度来切入重构社会再生产理论,希望能够向各位老师请教。我先讲讲自己为什么会从“交叉性”转到“再生产”的研究。实际上,对二者的关注存在内在一致性。2012年我写博士学位论文的时候,就有感于劳动研究与性别研究的断裂。劳动社会学中隐藏着“生产中心”的前提,强调“阶级”,而性别社会学则聚焦家庭等“再生产”领域,强调“性别”。但田野观察告诉我,仅侧重任何一方面都不能解释现实中“阶级”与“性别”之间错综复杂的关系。

在自回归生成模型、预训练以及人类反馈强化学习等技术的基础上,ChatGPT获得了强大的自然语言处理能力,颠覆了过往人们关于人工智能的认知。但与此同时,ChatGPT在模型训练、生成内容以及应用等维度也带来了诸多类型的风险。在治理展开之前,应当明确人本主义是治理的价值基础,包容审慎的敏捷治理是治理的理念,“点面结合”的多方参与是治理的主体要求,多措并举的体系化方案是治理的模式。由此,治理的具体路径将从以下五个方面展开:建设标准训练数据集、健全人工智能训练师职业资格准入制度、强化算法监管技术、落实全过程的伦理治理方案以及优化法律体系与法律责任配置。
