INTRODUCTION
The trajectories of human development can be divided into two dimensions: "Energy" and "information". Ian Morris, a professor in Stanford University, proposes that "energy" is a measure of civilization. Some scholars point out that China's every major dynasty change, or turmoil all lead to a large number of people's death, after which a large amount of vacant lands would be available for farming, and the whole social conflict could be solved. Even in modern, urban residents are forced to leave the city and become destitute and homeless because of partial wars or natural disasters, resulting in a great many refugees and casualties. As the main form of human habitation, cities have very efficient the energy supply system already, but still have some hidden dangers. When some force majeure occurs, cities cannot provide the necessary energy for residents, which reflects the significance of the mobile smart house as a part of the energy management of individuals and organizations. China's carbon emissions peak and carbon neutrality policies are major policies on the energy transition and management, which will affect the whole society and environment in China in a long term.
Another trajectory of human development is information; As human development creates and accumulates more and more energies, how to mobilize and organize these energies becomes an urgent issue to be solved. Information is the key to mobilizing and directing these energies. In terms of the competition of civilization, more energies can be deployed and keep dominant, apart from this, it is also necessary to have stronger organizational ability and communication ability, which depend on the transmission of information. In modern, technological revolution is usually connected with information, from telegraph, telephone, radio broadcast, television, radar, computer, Internet, mobile communication, to today's hit terms such as big data, cloud computing, artificial intelligence, block chain, quantum computing and quantum communication, are all related to information. Information, therefore, is another thread running through human history. As the main direction of urban planning in China, smart cities collect information at the micro level, analyze and process it at the macro level, and then influence the individual's behaviors and feelings, carrying out an overall management of urban operation from the perspective of information to improve the life standard of residents and enhance the efficiency of social operation.
China has actively confront the challenges of increasingly serious climate crisis, shortage of the clean energy and the overall improvement of social operation efficiency, and formulated a series of solutions and policies, including smart city and double carbon policies. Mobile smart houses pursue to provide a free-living state compatible with energy management and information collection management functions for people. It is an organic integration of smart cities and carbon emission peak and carbon neutrality, which has positive significance for promoting national planning and meeting people's needs. Zhang (2015) (1) The smart city system is an urban system form that developed through well integrating the intelligence of emerging information technology and the wisdom of people in the urban context, with the aim to promote the overall optimization of urban development. (2) The smart city system includes elements five major subsystems such as strategic system, social system, economic system, supporting system and spatial system. From the perspective of its structure, the hierarchies of the smart city system is divided into three layers including the physical layer, the activity layer, and the strategic layer. (3) The system model of smart city describes the major component factors of a complete smart city system and expresses the connection and function mode of different factors according to certain construction forms, revealing the internal mechanism of the formation, operation, and development of smart city system. Wang (2022) In 2020, China proposed that it strives to reach carbon emissions peak before 2030 and realize carbon neutrality by 2060, at the 75th session of the UN General Assembly. This goal is proposed on the guidance of the long-term temperature control goal proposed in the Paris Agreement, to advocate green and low-carbon development and realize carbon emission transformation This goal's realization requires the cooperation and coordination of economy, energy, and technology in the whole society.
