我国快速的工业化带来了雾霾污染的加剧和空气质量的恶化，同时，城市化水平的不断提高使得我国的城市空间格局发生了巨大改变，相比以往基于地理邻近讨论产业集聚环境影响的研究，提出了新的区域污染扩散机制，关注基于城市网络联系的空间溢出效应。采用空间杜宾模型，利用区域之间的制造业投资联系构建投资权重矩阵，使用2004～2018年的中国284个地级市面板数据，分析基于城市网络联系的产业集聚对雾霾污染影响的本地效应和空间溢出效应。结果表明：产业集聚有利于降低当地的雾霾污染水平，且通过基于城市网络联系的空间溢出效应显著降低产业联系紧密区域的雾霾污染。此外，科研投入也有助于减少区域内的雾霾污染；第二产业为主的产业结构，会加剧本地雾霾污染，并且通过空间溢出加剧产业联系紧密地区的雾霾污染水平。同时，基于网络联系的产业集聚对雾霾污染的空间外部性表现出了区域的异质性。

当今世界正经历百年未有之大变局,世界各国科技竞争加剧,科技创新成为各国博弈的主战场。我国在基础研究、关键核心技术等领域正在遭受西方发达国家的围堵。高校作为基础研究主力军和重大科技突破策源地,传统科研范式在响应国家重大需求方面存在原始创新能力薄弱、科技成果转化率低、协同创新能力不足等问题。持续增大的外部压力、创新高风险与高投入使得“有组织科研”成为当前我国高校提升创新效能的重要选择,也是高校深度融入国家创新体系的重要举措。阐述“四个面向”和“有组织科研”的内涵,梳理“四个面向”与“有组织科研”、“有组织科研”与自由探索的关系,从高校传统科研范式亟待解决的问题入手,构建基于“四个面向”的高校“有组织科研”范式,对重庆大学“有组织科研”实施路径与成效进行解析,验证理论的科学性与适用性。

刑事证明中的预测性算法证据研究

中国人民公安大学学报（社会科学版） 2024年第1期40卷 75-88页

作者：刘宇琪秦宗文南京大学江苏南京210000

预测性算法证据是由算法将个案与类罪行为模型对比后导出的异常行为数据,可以预测并提示潜在的犯罪风险,通常作为侦查线索适用。但实证考察发现,其亦作为指控证据使用并对法官定罪心证产生影响,同时存在法律资格不明、审查方式混乱无序... 详细信息

预测性算法证据是由算法将个案与类罪行为模型对比后导出的异常行为数据,可以预测并提示潜在的犯罪风险,通常作为侦查线索适用。但实证考察发现,其亦作为指控证据使用并对法官定罪心证产生影响,同时存在法律资格不明、审查方式混乱无序等问题。预测性算法证据本质上属于裸统计证据,与待证事实的相关性较弱,推理链条不牢固,若直接将其作为定案证据可能会产生一系列负面效应。为了平衡预测性算法证据在刑事证明中适用的积极价值与可能产生的负面效应:一方面,在审判中心主义视角下,探讨预测性算法证据的证据准入资格、定案证据资格审查以及证明机制构建等问题,以形成科学合理的证据能力和证明力审查规则;另一方面,从侦查重心主义视角出发,明确侦查机关对预测性算法证据的初步审查和随案移送等义务,以及对全案要达到“排除合理怀疑”的证明标准,以保障实体真实。
