Huang Qifan, the former mayor of Chongqing, recently issued a document saying that the digital economy driven by big data, cloud computing, artificial intelligence, and blockchain is changing in our lives. The interconnection, sharing and sharing of data are typical characteristics. However, if the collection standards are inconsistent in all aspects of data operation, it is difficult to achieve shared sharing. This is like a railroad track that a train runs on. If you have a wide track or a narrow track over a certain distance, the speed of the train can't get up, let alone run the high-speed rail. Promoting the standardization of data collection is the key and basic measure of the data element market.
