Research on big data and new smart city construction

Smart city is to achieve efficient government management, convenient people's livelihood services and sustainable industrial development through the interconnection, comprehensive perception and information utilization ability of things, things and people, and the new generation of information technology such as internet of things, mobile internet and cloud computing. “Smart city” aims to use the new generation of information technology, change the way people interact, improve the real-time processing ability of information and the speed of sensing and response, enhance business flexibility and continuity, improve the efficiency of resource utilization, realize green energy saving, and promote the comprehensive and sustainable development of various social undertakings. From the content of smart city construction in each city, on the one hand, it is to strengthen the construction of urban basic communication network and improve the bandwidth and coverage of communication network. On the other hand, it is to provide smart application services in key areas, such as smart public services, smart social management, smart transportation, smart medical care, smart logistics, smart housing. Smart city is the only way to realize the sustainable development of the city. Smart city is the necessary stage for the development of urban informatization to wisdom. At the same time, in the process of building a smart city, it will also drive the overall development of related industries and become a new engine for economic transformation, industrial upgrading and urban upgrading. If we compare a smart city to a person, the internet of things is the sense organ, the mobile internet is the nerve, cloud computing is a strong body and heart, big data is a smart brain. If smart city leaves data collection, data analysis and data use, smart is empty talk. Big data is the key supporting technology for smart city to realize “intelligence” in all fields, and the construction of smart city can not do without big data. From government decision-making and services, to people's way of life, to the city's industrial layout and planning, to the city's operation and management mode, big data will spread in all aspects of the smart city, which will be “intelligent” under the support of big data. This paper uses conceptual model and multidisciplinary collaborative research methods to integrate innovative thinking led by big data into urban construction to help modernize social governance capacity and governance system.
