近年来，随着大数据战略深入实施，大数据事业在全国各地的发展欣欣向荣。党的十九届五中全会指出，要坚定不移建设数字中国，加快数字化发展。在党和国家政策指引下，各级地方政府纷纷将大力实施大数据战略行动、优化提升各领域创新驱动能力作为推动经济高质量发展的重要举措，区域大数据发展百花齐放。本报告从城市群的分析视角，围绕五个代表性的城市群区域，以其中心城市的评估数据为基础，系统评估和比较分析了各代表性城市群大数据发展的综合水平以及其在大数据政用、商用与民用方面的发展成效。具体评估来看，粤港澳大湾区与长江三角洲地区大数据发展整体处于领先地位，京津冀地区内部差异性明显，成渝及黔中地区表现亮眼。区域数字一体化已呈现由粤港澳大湾区、长三角、京津冀和成渝城市群领衔，多区域相互促进的“4+N”发展格局。
In recent years，with in-depth implementation of the big data strategy，big data is thriving all over the country. The fifth plenary session of the 19th CPC Central Committee proposed that，we should unswervingly build Digital China and accelerate the development of digitalization. Under the guidance of the Party and national policies，local governments at all levels have vigorously implemented big data strategic actions，optimized and improved innovation-driven capabilities in various fields，as an important measure to foster high-quality economic development，producing fruitful results in regional big data development. From the perspective of city cluster analysis，this paper systematically evaluates and compares the comprehensive level of big data development in representative city clusters，as well as its development achievements in big data application in political，commercial and civil aspects centering on five representative city cluster regions and based on the evaluation data of their central cities. Specific evaluation results indicate that，the Guangdong-Hong Kong-Macao Greater Bay Area and the Yangtze River Delta Region take the lead in overall development of the big data，there are obvious differences within the Beijing-Tianjin-Hebei region and Chengdu-Chongqing and Central Guizhou areas have an outstanding performance. In terms of regional digital integration，a “4+N” development pattern led by the Guangdong-Hong Kong-Macao Greater Bay Area，the Yangtze River Delta Region，Beijing-Tianjin-Hebei Region，and Chengdu-Chongqing city cluster and featuring mutual promotion between multiple regions has taken shape.
