The invention discloses a low energy consumption and load balance transfer calculating method and device based on a mobile cloud environment. Factor values influencing data stream application program division are obtained from a cloud server and a mobile terminal; data stream application programs are divided dynamically through combining with a data stream application program division strategy; the data stream application programs of the mobile terminal are transferred to be executed at the cloud server or the application programs of the cloud server are transferred to be executed at the mobile terminal; the factor values comprise the current load of the cloud server obtained from the cloud server and the current electric quantity, the CPU load, the network bandwidth and the usable memory space obtained from the mobile terminal. Through the scheme of the invention, the energy consumption of the mobile terminal is reduced, the load balance of the mobile terminal and the cloud is realized, simultaneously the throughput capacity of executing the data stream application programs by the mobile terminal is improved, the response time is reduced, and the operation efficiency is improved.
