政企合作作为促进政府数据价值实现的有效路径在全球被广泛实践,该方式不仅能有效提升政府数据开放广度与利用深度,更能提高价值实现效率。当前我国在政企合作上已有丰富实践,但仍与国际水平有差距,亟待相关研究提供理论与实践支撑。文章基于对当前我国各地政府数据价值实现中政企合作实践调研,以公共基础设施建设领域政企合作成熟模式为参考,依据投资方式不同、适用场景差异、合作流程的不同,划分我国典型模式并在比较不同模式的基础之上提出模式应用路径。文章将我国政府数据价值实现中政企合作模式划分为BOT、BPO、BT、PFI和JV 5个模式,通过比较发现,五种模式在适用项目、运营特点、运营周期、优劣势5个角度存在明显差异,基于不同模式的差异,本文从模式选取、模式实施和模式优化3个层面提出了政企合作模式应用路径,为我国政府数据价值实现的政企合作提供理论支撑和参考。

大数据时代数据成为基础性国家战略资源,加强数据产权政策建设是国家战略的重要内容。文章通过采集我国数据产权政策有效样本,基于政策工具理论、行动者网络理论,从“工具-目标-主体”三维视角分析数据产权政策,梳理我国数据产权治理路径,剖析当前治理路径存在问题并提出建议。文章发现我国数据产权治理共分为“环境架构”“基础支撑”“价值开发”“市场发展”4条总路径,基于政策发现各路径存在问题,并提出治理路径:整体上调整治理路径布局,平衡各目标治理需求;“环境架构”路径上重视多层次治理方式,建立持续智力支撑机制;“基础支撑”路径上拓展多层次治理方式,强化数据安全目标与主体的匹配;“价值开发”路径上平衡数据价值实现目标,拓展多元主体功能空间;“市场发展”路径上纳入数据市场关联主体,着重完善相关激励方案,力图完善我国数据产权治理路径。

跨境数据流动因巨大的经济价值和潜在的地缘政治风险成为数据治理议题关注的焦点。目前世界跨境数据流动处于以欧美为主导的区域性合作与妥协的跨境数据流动规制下,我国推动国际跨境数据流动的多边治理合作道阻且长。文章调研欧盟、美国、日本、俄罗斯等重要组织和主权国家的跨境数据治理政策,结合双边和多边区域贸易协定,梳理国际跨境数据流动规制的内部机理,剖析全球跨境数据流动多边合作治理存在的困境,提出符合我国价值导向的变革路径。文章将跨境数据流动治理内部机理划分为规制主体、规制客体与规制手段等3个维度,分析国际跨境数据流动治理合作的价值理念互斥、监管制度模糊、区域合作碎片化的现实问题,提出以普适共赢为优先的规则制定、以独立机构为依托的第三方监管、以例外条款为补充的合作前提等3种国际跨境数据流动合作治理变革路径,为我国融入全球跨境数据流动治理提供参考。
