摘要:

近年来,数据要素交易与数据要素市场建设受到社会各界的高度关注。区别于传统生产要素,数据要素存在“准公共品”性、信息不对称性与负外部性等经济特征,这些特征是当前阶段阻碍其大规模流通的主要因素。结合数据要素的经济特征,从技术视角切入,探索基于多方计算的数据交易机制在现有政策与市场环境下的实践应用,通过“数据可用不可见、数据使用可控可计量”的交易机制,为现阶段数据要素大规模流通提供一种解决思路。同时,深入分析北京国际大数据交易所已上线的数据安全融合产品,为基于多方计算的数据大规模流通工程化落地与数据要素市场建设提供借鉴。

关键词: 数据要素交易, 多方计算, 可控可计量

Abstract:

Recently, data factor transaction and market construction have received high-level attention.Different from traditional factors of production, data factors have economic characteristics such as “quasi-public goods”, information asymmetry and negative externality, which are the primary reasons hindering the large-scale circulation of data at the current stage.By taking these economics characteristics into consideration, and from the perspective of technique, the practical application of data transaction mechanism based on multi-party computation under current circumstance of policy and market was explored, through a transaction mechanism of “data is usable but invisible, usage of data is controllable and measurable”, which provided a technical solution for large-scale circulation of data.In the meantime, the data service based on multiparty computation was analyzed, which was already launched on the data transaction platform of Beijing International Data Exchange.And the practical implementation of large-scale data circulation based on multi-party computation and data factor market construction were provided.

Key words: data factor transaction, multi-party computation, controllable and measurable
