The 2023 2nd International Conference on Information Economy, Data Modeling and Cloud Computing (ICIDC 2023) was therefore held during June 2nd to 4th, 2023 in Nanchang, China (hybrid form). The Conference was attended by more than 100 participants and hosted four keynote speeches, more than 60 oral presentations as well as various poster presentations. The proceedings of ICIDC 2023 cover various topics, including Big Data Finance, E-Commerce and Digital Business, Modeling Method, 3D Modeling, Internet of Things, Cloud Computing Platform, etc. All the papers have been checked through rigorous review and processes to meet the requirements of publication. Data modeling allows us to obtain the dynamic change trend of various indicator data, so how to use big data information to model and study the development trend of economic operation plan is of great significance. And that is exactly the purpose of this conference, focusing on the application of big data in the economic field as well as conducting more profound research in combination with cloud computing.
