当前，大数据发展日新月异，数据与社会经济深入融合，数据资源成为各国或地区竞争的关键要素，数字竞争力赋予了竞争力新的内涵，是未来核心竞争力所在。本文提出数据价值链竞争模型，聚焦数字创新、数字经济、数字治理、数字服务、数字安全五个评价维度，构建数字竞争力指数，旨在衡量和评估全球各国或地区在数字化转型发展过程中产生的竞争优势以及凭此优势带动其他领域发展的能力，为各国或地区把握当地数字化发展形势提供重要参考。
At present，the development of big data is changing with each passing day，with data and social economy deeply integrated. Data resources have become an important element of competition among countries and regions. Digital competitiveness has given new meaning to competitiveness，making it the core competitiveness of the future. With the digital value chain theory as its theoretical model，this paper focuses on five evaluative dimensions（i.e.，digital innovation，digital economy，digital governance，digital service and digital security）to make the global digital competitiveness index. By evaluating the competitive edges of different countries or regions in the digital transformation，and its capacity to drive the development of other sectors，it thereby provides important reference for countries and regions to better make use of local digital development trends.
